I hoped to return this room divider but learned too late it doesn't have free returns. I bought this and another one that didn't have the solid wood on the bottom and had smaller rectangular wooden lattice. The other one looks great. On this one, the backing paper material was very sloppily glued on and has a wrinkled appearance on all four panels. The other screen I purchased was glued properly and the paper is nice and flat and neat looking. I do like the basic design of this, but am pretty disappointed because it looks sloppy and cheap because of the paper. The paper looks yellow in my photo because of lighting, it is white.

Worth the investment

I had to order this in an emergency. To put it in brief words, I live in a two level studio unit. My bedroom TV fell backwards off the bureau accidentally and down the stairs to its demise. Putting this together was no problem, instructions were thorough and easy. It came with several bars that connected together smoothly and an Allen key for the brackets and screws for the feet. I did one less horizontal bar on top and bottom so it could fit, which was great because with all of them on it was too long. However I ran into the difficulty of the horizontal bars popping out of the brackets during the last stages, but eventually got it done. I was also looking for a specific type of divider where I could adjust the feet so I could tuck it in between the dresser and banister. Glad I made this purchase.
