    From the moment we walked in, we were warmly greeted by John Ruiz. I had already done some research…read morebeforehand and had an idea of what I wanted, and John truly listened. He guided us through the pressure test and then showed us mattresses not only based on those results, but also tailored to our specific goals: we wanted something that stayed cool, had strong edge support, was great for side sleeping, reduced motion transfer so I wouldn't feel my husband moving around, and would work with our current adjustable frame. We thought the process would take 2-3 hours, but thanks to John's knowledge and attentiveness, we found the perfect mattress in under an hour! The bed is being delivered the very next day, which was such a bonus. What really stood out was that John never once tried to upsell us on things we didn't need he was thorough, detailed, kind, and knowledgeable every step of the way. Thank you, John, for making the experience easy and enjoyable. I would recommend you a hundred times over!

    My experience at sit n sleep Ontario was akin to a never ending nightmare. I would not advise…read morebuying any mattress here, but if you do - Compare the Law/Legal tag on the mattress you try, and the mattress you receive. If you decide not to read, let your eyes tell the tale via the attached photos. To keep it relatively short, there is data on the law tags that tells you specifics of the mattress. One is "Net weight of internal filling material". This is essentially your wools, latex,polyfoam, fibers, feathers, ie the expensive stuff for the Comfort Layer. We tried a mattress in the storeroom that was a medium firm, very comfortable - we bought it. Received a mattress, Hard as a rock, mind you we gave it over two months to 'wear in'. After comparing both LAW tags. Our mattress had 55 pounds of internal filling material, store room had ONE HUNDRED AND TWENTY POUNDS. Yes, 130% MORE pounds of comfort material. Can you imagine HOW MUCH MATERIAL that 130 pounds IS? No wonder our bed was rock hard. The salesman and customer service will claim to have no idea what it means (despite their combined 50 years of experience) laughable. Yet these industry professionals have no idea what information a basic mattress law /Legal tag is providing. Intentionally dishonest. We opened an investigation with them so they asked to give another chance and send a replacement. Their delivery truck arrived and we rejected a worse mattress with even less filling material. We verified our information with other stores/professionals to validate. We were knowingly deceived. At every step of this nightmare, the personnel became more unbearable. The customer service was incredibly rude, inappropriate, and hung up on us multiple times. Its all clouds and rainbows until their warranty or money is in jeopardy. Their customer service even tried to tell me lies about me confusing the law tag with the store price tag. Intentional dishonesty. We finally had enough and requested a refund, they couldnt promise a full refund they stated. The 3rd time we were hung up by customer service on was due to our unavailability to a same day pick up of the return. Once their team arrived to pick up the mattress, they grabbed the pillow cases, adjustable base, protective sheet, extra hardware - and said the mattress was not on the refund sheet, REFUSED to take it, LEAVING the mattress. To be fair this was likely the company that botched this, willingly or not. After going somewhere else i realized how low quality the adjustable base even was. Please think twice about going to Scam n' Sleep. Deceptive, Fraudulent, Dismissive, Inappropriate, Dishonest. I have never had this experience with this size of a legitimate company before Id wish it on nobody else. Go elsewhere. If nothing else - see with your own eyes with the attached mattress tag photos.

    DO NOT BUY TEMPUR-PEDIC! We have had this bed not even 5 years, last year it started sagging on…read morethe sides. We contacted warranty and they said it wasn't enough to quality for warranty replacement. We contacted warranty again when it started sagging greatly on the edges and they refuse to honor their warranty! We spoke with Lauren( their supposed manager and only manager) who was not only rude but also useless in warranty department, saying that they refuse to honor their warranty. If you go onto the BBB you will see that they have MANY complaints regarding them honoring their warranty claims. We spent over $3000 on this bed for it to not even last 5 years. Their warranty department is an absolute joke and their beds are NOT QUALITY. Do yourself a favor and do not buy from them unless you want to deal with scummy people who refuse to honor what they promise.

    Beware of the the pillow promotions they have - the sales agents at the store told us to get the…read morepillows when they had the pillow promotions which is buy one get one free, and if we didn't like the pillow as long as the second one is sealed and in package, we can still return it so we would onl pay for half of the price for things that didn't work out for us and cut our loss. We bought it and purchased the pillows, tried it and didn't work for us. Came back to the store today and was told by the store manager that we couldn't return it for refund, only for exchange. Completely false advertisement! Though the store manager is kind enough to make exception and refund us, but false advertisement is false advertisement.
