This piece looks great in our spare room and it can offer both extra seating and accommodate overnight guests. It was easy to put together, but best with two people. We also added some furniture gliders on the feet so it can be rearranged easily. I followed the advice from other reviewers to use a 10" XL twin mattress for the top, and a regular twin for the trundle. I totally DISAGREE that an XL is suitable. We received an 8" twin, but fortunately for us the XL shipping was delayed. So we placed the regular twin on top, and it fits perfectly. There are no gaps, and allows enough space to tuck in bedding on all sides without struggling. Whenever the XL arrives we'll be exchanging it. The minor detail flaw is that there were so many threads to snip off. I arrived earlier than expected (yay) and the piece was shipped in three heavy boxes, so you'll need help to move them to your space. I can't say enough good things about the excellent customer service!!
