GOOD BUY
Color: Grey, Number of Items: 1
This is a good sturdy table. It is the perfect size for an end table or nightstand. The USB ports and Outlets really come in handy. It is made out of real wood which is rare, it is definitely worth money.

Very Nice End Table! Sturdy!
Color: Ink Black, Number of Items: 2, Color: Ink Black, Number of Items: 2
These are great tables, especially to use along side a recliner and couch. They're easy to put together. Follow the directions! Everything you need is in there including the screwdriver!! Lay it on its side on the floor when your building it, tighten all the tabs a half turn and did I mention?... never use power tools when building small furniture like this. once they're done, you'll love them... there's a nice drawer to keep things in -- remotes, etc It's pretty, sturdy, I bet will last a long time. ♡

Nice Side Table
Color: Ink Black, Number of Items: 1
This is a nice side table. The assembly hardware is of good quality. The wood product finishes are very nice and the pieces assemble solidly. The instructions are easy to follow except for the drawer slides where a little more concentration is needed . . . or maybe it’s just me.
