Great table!

Just what we were looking for! The table was well made and went together very easily (my husband and I did it in well under an hour). We were very pleased with the quality of the wood. The only thing I would suggest to the company is that the glide parts weren’t labeled with stickers like every other part was. That would have been a big help.

Some frustration, but overall worth it.
Color: Ink Black, Number of Items: 1, Color: Ink Black, Number of Items: 1
Sturdy. Everything came in one piece and the instructions were some of the clearest I've encountered for Amazon furniture. Took about an hour for me to muscle my way through with manual screwdrivers only. I do not recommend a drill unless you go slow, because screw placement will make or break this for you in my opinion. Problems I encountered and how I overcame them: Drawer was rickety, kept catching when trying to pull out. I had to go back and tighten the tiny black screws on the rails. If they are not as flush as you can possibly get them, they will cause the wheels to catch. Once I got them as tight as possible, the drawer pull out was much smoother. Getting the first set of rails on. Space was EXTREMELY tight and frustrating. I ended up using a small screwdriver from my house, pressing it tightly with one hand, and using a pair of pliers to turn the screwdriver. Like a socket wrench type action. This sucked, I can't lie. And it wasn't possible to put them on earlier due to the cam bolts/screws under the rail. But I got through it. Overall, this is worth the money as long as you are willing to take your time and line things up properly and really use some elbow grease to get the screws in straight and flush.
