I was sent here by my doctor to see if I had sleep apnea. I got there at 8pm and was greeted by the tech. He was very professional and answered my many questions. It was a bit difficult falling asleep. But that's mostly because of the sleep apnea, and all the wires stuck to my head and legs. Ear plugs are provided if you're a light sleeper, but I didn't have to use them. I was woken up around 2am to try a cpap machine. Again, the tech was polite and helped me figure out which setting worked best. After a few minutes of adjusting to a machine helping me breathe, I was out again. I was then woken up at 4am and was ready to be released (after all the wires were removed). The place was clean and neat. Not the softest bed, but again, I was there for observation, so it's to be expected. The service was top notch. read more

I parked in front of their building and asked them if I could leave my car there overnight for my sleep study and they told me "yes". I did not see any parking signs. Today I got a parking ticket. I called them, left a message and THEY NEVER RESPONDED. A courtesy call saying "sorry" at least. read more

RUDE RUDE RUDE. "MARK" was the name he sarcastically gave me. I called on 3/15/2026 at 1:48pm. (Sunday) Mark said even though I have been emailing, calling and leaving messages for over 7 straight days at the Wilshire location, no one has called after I left the authorization number on the voicemail and attached it to the emails, there was nothing he could do until someone gets it from "the pile of faxes". Just a shame! Mark then says to me "we are overwhelmed and understaffed" (as he breathes hard like a big ole freight train on the phone clearly from sitting there eating snacks allllllllllll shift). So, Mark what does that have to do with me? I noticed this was the only location open today. I was calling the Wilshire location for over 7 days and nothing, so I tried Alhambra. I even calling on the weekends because the Alhambra location is open on Sundays, so I was hoping for Wilshire as well. Mark is disgusting. If you hate your job Mark, then quit. I am definitely calling Illinois and going in on LinkedIn and finding anyone affiliated with this individual and this company. Mark was short with me and offered no solution when asked, "well what do you suggest I do because if no one is going to respond to me until you hire more people, train them, then shovel the fax machine out to continue the appointment process, then how are services supposed to be rendered"? He said nothing but "wait util we clear the fax machine and get around to returning calls". Kept cutting me off and wouldn't allow me to speak. The absolute nerves. OK! LET ME JUST LET EVERYONE KNOW HOW BASURA YOU ARE. read more

I honestly don't know why there are so many negative reviews. This facility was clean, orderly, and all the employees I encountered were professional, respectful, and helpful. Jason and Danny went above and beyond because of a different issue I was facing due to my insurance transportation. I really appreciated their understanding and help. My only challenge was scheduling the appointment as I needed a specific kind of study and the scheduler had to reschedule me several times. I know that sleep studies are not something you can schedule and get done right away but it was frustrating to have to wait for the initial scheduled appt only to then be rescheduled again and then again a month later. But the experience of the sleep study was fine. They provided breakfast and lunch for my extended study as well. I wanted to post because there were so many scary reviews when I was searching but I was referred to this clinic so I had no choice. No need to be afraid! They were great! Oh I also wanted to mention there was a female employee who started my sleep study and she was also professional, respectful, and polite. Setting up all the wires can be an uncomfortable experience and she was very thoughtful explaining before doing anything which I know is important for a lot of people. read more

This review is for the location on Hill St. in Pasadena. The location is easy to find and there is plenty of parking. It's on the second floor with stairs and elevators right next to each other. The door is clearly marked and when we walked in there was a water and coffee dispenser and one chair in the seating area. We were greeted right away and set up with professionalism. There was a futon for another person to stay and sleep in the same room at the patient. The tech would come in to reattach a wire if it fell off during night, always as quietly and gently as possible. The night itself was quiet even with other patients in the other rooms. Regardless of the results, I would say the sleep study experience at this location itself was smooth and painless. read more

The staff was incredible. They were extremely patient and accommodating. Unfortunately, the room I stayed in was connected to the hallway. I could hear everything going on in the hallway as the door was very thin and had a larger than normal gap at the bottom. Lots of light came through the gap. There was also a window covered by a thin curtain that allowed me to hear all the staff conversations. They probably were not aware of this issue. Unfortunately, the room was dirty. There was lots of dust and hair on floor. It was obvious that the room is not deep cleaned between patients. The worst part is that the room was also a storage room. There were seasonal boxes under the bed that were clearly visible. Overall it was a negative experience, but not because of the staff. I would not recommend this location for Apnea Study. read more

Downtown and unsafe Took a long time to check in and get all the contraptions on don't know how a person can have an accurate sleep study people snoring and people vacuuming on this floor Requested a sleep center close to home was sent here thank goodness the security guard stayed with me until my ride came! read more

So I finally got around to doing this sleep study to see if I qualify for a CPAP machine. It's not like I want one now that the sleep study is over. Having all these lines connected to my head and body I found sleeping to be that much harder. If I do qualify for a CPAP then I'll more than likely have a breathing apparatus over my nose or mouth or both strapped on my head. That would constrain movement which would not be cool. The technician was professional and answered all my questions regarding the entire process. The bed here is quite hard and uncomfortable but really it's all the leads connected to my head and chest that makes sleeping uncomfortable. The wall between me and the lobby were super thin and I could here just about everything that was going on in the next room. As tired as I was I felt like I couldn't sleep but apparently I did sleep for a couple of hours. The overall professionalism I recommend this place for your sleep study but bring a headset or earplugs so you don't have to hear additional noises. read more

This place was not at all professional from the physical appearance of the lab to the employee asking random questions not pertinent to the sleep study. I did not feel comfortable in this place. Heed this warning, do not come here. If you see this review, tell your doctor to refer you to a different company. read more

I read the reviews of this place and still gave them a chance. DO NOT DO IT. GO SOME WHERE ELSE. This office is a mess. The ladies are nice and try their best but the way they run their business is horrible. I made an appt in Oct for Jan and when the time came there was no record of the appt. So I was like ok no worries I can wait for another one. Earliest was May. Picked up the machine they explained to me not to touch the button during the night no matter what. They also gave me janky looking mis matched batteries. The machine turned off in the middle of the night I did not touch it per their instruction and when I dropped it off I let the tech know. She said they will let me know if its not enough data. I waited and eventually I asked my PCP about the test and it was inconclusive not enough data. No one contacted me so I was waiting all this time and prob would have waited even longer if I didn't have a PCP appt. Refused to refund me but booked me for the more exp in lab study at a discount that I didn't want. Good thing I didn't go thru with it because I called my insurance to find out they were out of network and it needed prior authorization. I called them back and the lady again said they are in network again. They said I would have to pay again if I wanted to redo the in home test. Which I do not think is fair because their machine turned off. At this point I was tired of having to go back and forth and did not trust them to do another test. I just accepted the loss of money but at least thought it would go towards my deductible for insurance. Right? WRONG. They said I was a CASH PATIENT and refused to file a claim. WHY IN THE WORLD WOULD I BE A CASH PT WHEN I HAVE INSURANCE. MAKE IT MAKE SENSE. I paid for the test in cash cause they said I didn't meet my deductible and had to pay for it before the deductible was met. But at no point at all did I say I was a cash patient or wanted to be a cash pt. So I got scammed out of a test and scammed out of the money going towards my deductible. You wanna know what the kicker is? I called my insurance and all my diagnostic testing is covered 100% I was not suppose to pay AT ALL. Thank god my insurance company is amazing and called them and basically said you guys HAVE to file a claim. Even then it took several calls to do it. I got my refund about a week ago. In my years of being alive I have never ever felt so frustrated, upset, and mad at any business. They will gaslight you and try and pin all the blame on you. I should have done more research because every other company I contacted after stated that they could take me in same latest same week. I literally went with a diff company and I got my machine within two weeks. Drive a little further. This company has been trolling me for half a year and delayed my treatment and it has effected my health. I will be reporting them to all the proper channels and I encourage all the others dealing with them to do so as well. read more

Phone receptionist Christopher from comfort Sleep Clinic is extremely unprofessional. He does not know the business hours of his business and he does not care to find out. He told me to find out from the Alhambra office, but I told him this is the exact number shown for Alhambra office. Then he realize he is the receptionist for all three locations. He then ask me to wait 1 min and hang up me. When I call back right away, he then claim he was going to call me back. What is dishonest stuff you guys have. Please prioritize on hiring the right personal that cares about your business. read more

Staff was lovely. BUT the clinic itself was subpar. Felt like a hospital room, not cozy in the least. But aside from that, my 1star has to do with the fact that I had my sleep test over a month ago and still no results sent. I have heard that this was unfortunately a problem with this clinic but I was hoping it was in the past. Nope. There is not enough urgency to the results. Please send results! read more

This place is absolutely disgusting! They didn't even bother to change the bedsheets.

I went to the new Hollywood location on Sunset Blvd. 9h30 pm to 4 am. Check in was all good, mattress comfortable. But the curtain did not close all the way because it was too short and there was really bright light outside mind you the front is a glass wall, so yeah nice and light, the cleaning crew worked till after 12 in the morning and was vacuuming and banging around ect. You must be kidding right? Then the AC triggered the lights to go on in my room, those are very very bright hospital lights! That happened 2 times from 11 to 2 am and I had to ring the tech to turn them off, took a while for them to come and you cant get up because you are wired up. My blanket had a nice big brown stain. I DID NOT GET ANY SLEEP AT ALL. The 2 times i dozed off the light show went off, the AC sounds like an airplane too. Total waste of time. How hard can it be to have a dark room with minimal noise for a sleep study? This felt like the KGB got me & was working a sleep depravation program to debrief me, by 4 AM I was pretty much ready to confess to just about anything. I can't believe it. If it was called sleep depravation center I could give them 5 stars. Creating zombies overnight. I have one question? How is this even possible? read more

I want to thank the technician working at the Wilshire office. I apologize for forgetting his name he made experience at comfort sleep clinic relaxing he was processional and also friendly. Thank you read more

I was scheduled for a sleep study at 7:30 pm. I've had several verbal confirmations as well as email proof. As soon as I got their the tech kept arguing w/me that they don't have appts at the time I mentioned and that I was wrong. She ended up calling a supervisor and was told I indeed have an appointment. She then said I would have to leave at 2 am if they started my study at 7:30. I said the paperwork indicated the studies end 4-6 am and that you can ask to stay until 6am and the tech said nope even though I have it in writing. I do not drive nor do I have anyone to pick me up. I explained I travel on buses. The tech asked me what's the earliest bus I could catch. Serious? At this point I said I would leave. There is no way I want to have a sleep study conducted by an angry person who cannot take accountability or apologize. I do not want to fear for my safety at a sleep clinic or outside at 2:00 am. This person kept trying to say I was wrong and kept trying to brow beat me the whole time. I left after all this drama. I do not have a death wish nor do I have the mental fortitude to let someone try to intimidate me because their existence is miserable. read more

I was sent here my doctor for my sleep apnea. I was at the Wilsher location in downtown LA. Easy to find and they let me bring whatever I needed to be comfortable. The tech Jason was so kind. He explained everything to me in detail and was more than accommodating. Although I had to give him a hard time for putting that electrical paste in my beautiful freshly done hair. Do bring whatever you need to stay comfy and drift off. The room is pretty much a bed and a small side table. So, I brought my ice water, my own pillow, my own blanket, a sleep mask, a small snack, and of course my favorite stuffed animal. Dress comfy (yes, you must wear clothes) you will have all kinds of stuff hooked up to you. And the bathroom will be around the corner so wear flip flops or easy to slid into shoes. If you go have someone drive you, they don't validate and it's really early in the morning when you leave once they get the information they need for your doctor. Hope if you're reading this you feel better. read more

This is by far one of the best sleep studies clinics I've been to. The staff was knowledgeable and I was able to fall asleep within 10-15 minutes. The results are fast, and they follow up pretty quick. read more

I will never be coming here again for a sleep study ! The staff is unprofessional none of the staff members ever introduced themselves (I told the male staff she never introduced herself to me. And he goes but I never introduced myself either! Yay ! You both are rude, the male staff was nice at first then somehow became standoffish but the female staff was unprofessional and condescending and I don't want to right a big ole paragraph but this lady never offered me a blanket the room was freezing there was a heater in the room but I didn't know because she never offered any of these things to me...thank god I brought my own pillow and small blanket! Also I almost left because she said I had to sleep on my back I don't ever sleep on my back ever !!and was about to leave because I only sleep on my sides because of my asthma after a bit the male staff came in and said it's ok if I sleep on my sides ! So by this time it was awkward staying over because she made it clear it would not work if I slept on my sides, and so he says to me that they get paid regardless if I leave or stay which I thought was rude and a very unnecessary comment lol! Because I wasn't trying to be rude I just can't sleep on my back But the most funniest thing was she kept talking about me because I could hear her gossiping to the male staff and the male staff was whispering but I could hear everything he was saying it's quiet in there I mean people where sleeping and my room is literally divided from them thru a thin wall hahahahahha! I did mention to him she was being rude and he says have you ever had a bad day? LOL!There is some other things that they did but it's super early 5 something in the morning and I need to sleep! JUST KNOW U NEED TO WEAR SUPER WARM CLOTHES AND BRING A THICK BLANKET ! read more

My office refers our sleep patients to this clinic, the service here is unacceptable. They say the report is ready in 14 business days but the patient in question is going on 17+ business days now and is still not ready. I have given my name and phone number to Monica and Samina and they never call me back. Every time I call for them, they are never there or have "just left". Horrible.. My Doctor and staff will never refer to this clinic again. My patients have complained that there the lady on the phone is not very fluent in English and can never understand her. Very unsatisfied and I feel horrible for my patients. read more

Best place for sleep study . Very clean and comfortable place. Great employee . Very helpful . Secured parking .

Doctor sent me there to do a sleep study at home with one of their machines, the day before I called to see if the machine was available for the next morning, they said yes, so next morning I went, machine was not there so I went to my doctors office to tell them to send me some place else, the girl at the office called comfort sleep and was told that the machine was there so I went back and the guy that told me no machine said to me did not tell you that there's was no machine then they said that they are going to send me the machine by ups, never happened so I went and got it I used it as directed and took it back, yesterday I went to see my doctor for the results and they don't have any record of me using the machine read more

When I called to schedule my sleep test, I was greeted very professionally by the operator. The operator confirmed my appointment time of 8 pm on 8/17/16. I was told to bring what ever I need to be comfortable, and to arrive 15-30 minutes early to fill out all of the paperwork.The business hours are listed as 7 pm-8 am. When I arrived at the location at 7:30 pm I thought that I would just walk right in and get started. But, to my surprise, both lobby doors were locked! So, I called one of the numbers listed on the door. Wouldn't you know it, no answer! You would think that if they open at 7 pm, that someone would be there at 7:30 pm to answer the phone. Now three other people have arrived to the location, and tried to enter the building, only to find that it was still locked. At 7:45 pm I called the 2nd number that was listed for emergencies, finally, I got a hold of a live person who told me that the technician was running late due to car problems, and that she would be there in a few minutes. Well, at 8 pm I called the number again, and to my surprise I got an answering machine instead of a operator. So, I left a message. A few minutes later my phone rang, and it was the emergency number operator. The operator told me that the technician was on her way and that she would be there in a few minutes. I asked if there was only one technician for all of us, and the operator said no, another technician comes in at 8:30 pm. Well wouldn't you know it, both technicians came in together around 8:20 pm. Fifty minutes late!! After making four people wait nearly a hour, on a busy sidewalk, in front of a locked building for a appointment that the company set the time for. All we got was, I am sorry for being late. If this is being a professional establishment, I and three other people beg to differ. I call this very unprofessional! Once we got inside, all of us were handed a clip board and some paperwork. When I got to one of the last pages to fill in, I noticed that one page was a survey regarding the service that I received during the study, and the survey was to be turned in with the rest of the paperwork. How can you, and why would you, fill in a survey before the service is completed? So, I told them that I would fill out the survey after the study was completed. When I called to make the appointment I asked if there were any restrictions on the position in which I sleep in. I was told no. When I was finally all hooked up and ready to go to bed, the technician told me that I have to sleep on my back the entire night. I told her that I can't sleep on my back, and she said that I have to. I tried for around 10-15 minutes before I said the hell with this, and turned on to my side, and fell asleep. When I was awakened just before 5 this morning, I was told to get dressed quietly, and then to go home. Of course there was no mention of me completing the survey. I wonder why!? I would not recommend coming here for your sleep test. read more
