Looks nice in my office. So easy to assemble that I didn't need the instruction sheet. Wayfair recommends an 8" mattress. I found this left a gap of a few inches between the top of the mattress and where the gray backboard begins. I need it to look like a sofa, so adding a quilt wasn't an option. A 4" foam pad under the 8" innerspring mattress did the trick. Recommend a 12" mattress.
