This twin daybed with trundle is amazing. It looks so nice, and is well put together. 

One thing that everyone should know. The top mattress needs to be thicker than the cheaper 6 or 8 inch mattress. We went with a 11.5 inch Sealy. If you do not get the higher mattress you will see a gap (the wall) in-between the top of the mattress and the back support. We went with a 8.5 inch mattress for the trundle, witch fits great. But we cannot keep a pillow  on the trundle bed while it's pushed under. Maybe with a 6 inch mattress you could fit a pillow as well.
