Adirondack sells unfinished wood furniture from a variety of manufacturers, including some regional…read morebusinesses and the vaunted Amish furniture makers stock.
The workmanship varies, but in general they have what I'd call medium to medium-high quality pieces. They will sell them to you finished at premiums which vary quite a bit from piece to piece, or will give you advice about staining or painting (and will sell you the appropriate paints and stains). If you've never finished an unfinished piece, it's not that hard to get a nice result, although you'll want to start out on a cheap, small piece to get the hang of it.
Pine predominates, but they have a half dozen other woods for many of the items ranging from parawood to alder to ash. There's some very nice oak pieces with good grains. The quality of the woods is what I'd call "modern" - finding good furniture wood these days is very difficult, and there are flaws in almost every piece of new wood furniture you can find, but they do reasonable quality control here. We've had a few pieces that had flaws from here, so I encourage you to look at the delivered piece before you take it off the premises - they've willingly exchanged things for us so don't be shy about that.
As far as the types of things, they have: bookcases (including corner units), headboards, shelving, kitchen tables and hutches, tables, dressers, desks, and a variety of interesting smaller-run items. They don't have couch/futon frames, however. The stock does vary - they do buying trips periodically - but for the more mainstream pieces they can get virtually any size in any wood or configuration you want. You can also bargain hunt here -- they typically have a few "as is" or end-of-run items at fairly decent discounts.
Wood is not cheap, relative to pressboard, but we've priced their stuff against internet-ordered, places like Huck Finn's, and equivalent finished furniture at the mainstream furniture stores, and Adirondack does quite competitively.
The staff here have been helpful - primarily Brian, the guy out front most of the times we've been here, who knows his furniture and will go over both the options for something and the finishing how-to with you. Do note it's a smallish operation so you may have to wait for help.
Some things I'd like: a sustainability rating on the wood (they don't have anything like this, although they can at least tell you where they bought the piece from, which is more than they can at most furniture retailers), and a delivery service (this is strictly carry-out). And, it should be noted that when they run out of stock of an item, it takes them a long time sometimes to get it back, since they do the buying directly themselves and then periodically. They do have a good-sized warehouse in the back, though.
Note: this is in Niskayuna, 12309, on State just on the other side of the Colonie line and below the intersection of Balltown to the south of Mohawk Commons. The Yelp Map seems to give the wrong location because of the "Route 5" addendum. Note also the URL for the store is incorrect - google for Adirondack Wood Shed. Phone number is 518 346 2200, current hours are MWF 10-530, T Th 108 and Sat 10-5. I submitted an update to Yelp but they seem to vary quite a bit in their times to update. I'll delete this section of the review when I see that the Yelp database information is correct.
