They material is of good quality, and the price was really good.  I am not too happy about the fact that they back is very skinny. There is a gap between the mattress and the back, where the wall is exposed. I dont like the way it looks, and the remote control falls back there. I almost looks like it is missing a piece. The back should be twice the size. It also looks odd from the side because of the way the back is made. The description says 8" mattress is recommended, so I ordered an 8" mattress for the trundle and a 10" mattress for the top.
I ended up putting the 10" mattress on the trundle, and I have to return the 8" mattress and get the 12" mattress. I am hoping that will close more of the gap in the back. It does not have a weight limit listed. The wood cross beams that hold the mattress are kind of small, but it appears to be sturdy.  The picture shows the 10" mattress in the trundle and the 8" mattress on the top. I gave it three stars because of the way the back is made.
