The bed itself is very nice, however, in the description Wayfair recommends a 10" mattress so this is what we purchased (also from Wayfair) and the mattress on the trundle will not fit under the daybed. The edge that the mattress slides under is unfinished and very rough (you normally wouldn't see it so that doesn't matter) but the 10" mattress would have to be forced under and it would ruin your bedding quickly. Now we left with altering the bed some way (sanding or trying to cut a piece out of a brand new bed we just bought) or adding some sort of footing to the bed to raise it so the trundle can go under. Doing this would add a gap between the bed and the front of the trundle which is less than ideal. Mayfair-please change this recommended mattress size in your description so other people wont be as disappointed as I am.
