I did my research and this was going to be the best queen-sized futon I was going to get for my budget. Have had two different guests (both couples), no complaints... maybe they were being nice? Haha
ASSEMBLY: Instructions were clear. I assisted my husband and it was pretty easy, so that made us happy.
MATERIALS: The matress had this awful chemical smell for several days. Had to leave the window open for it to air out. Matress also is very cheap material, several ripped spots around stitching. No big deal if you're going to use bedsheets (Which you should) or blankets to cover. It is definitely not 10" deep or whatever the description said in terms of the matress cushioning. It's pretty dang firm and more like 7.5". If you want to add extra comfort, get a pillow top comforter. All other materials are nice, good enough, pleasing to the eye.
USE: It fills up our room nicely, and has been great for the guests we have had. It's a true queen size, fits my queen bed sheets fine. I wouldn't pay a cent more than $400....Definitely don't pay extra or fret over the color of the matress. You're going to want it covered anyway at all times.
