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.

Nice and sturdy side table but the white is not white
Color: Farmhouse White, Number of Items: 2, Color: Farmhouse White, Number of Items: 2
This is a nice-looking and sturdy side table. We found it easy to assemble. It works well in small spaces. Be sure to check the dimensions so you aren’t surprised by how narrow and long it is. The drawer is small, but big enough to hold some remotes or other small items. We ordered the white with brown top. Unfortunately, it definitely is not white but more of an ivory or cream color.

Great table!
Color: Espresso, Number of Items: 1, Color: Espresso, Number of Items: 1
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.
