I do like this table. The directions are less than desirable. I have put together MANY pieces of furniture. I put this entire thing together and realized at the end that I had some pieces backwards so the top would not collapse back to coffee table. Luckily when I took it back apart, I did not damage it beyond repair. It looks great and perfect size for my apartment livingroom. Great option to be able to use as a dining table on the rare occasion I need one. Price was right and it is pretty sturdy. Extra storage underneath for books and such.

Awesome

Color: Black

Wonderful coffee table. Easy to assemble. Very durable, even when the table is fully folded out. Any little touch will leave fingerprints though, so be prepared to clean it a bunch

Cute and easy to use!

It came quickly and the directions were easy to follow! I will say that we used our electric screwdriver instead of the one provided just for when you’re screwing in the hinges— the one they provided was like dull and hard to use for that. But other than that it was seamless putting together. We use it almost everyday for kids schoolwork. I love storing their school books underneath as well. It’s lightweight enough that my kids (6 &7) can set up and put down the table themselves and it’s sturdy when using the full table or the pull up half table. Highly recommend!
