LOVE this! Put it together by myself in less than an hour, with nothing more than what came in the box. I had trouble fitting two of the attachments together, but with some force, I managed. Seems very sturdy. I bought the Alwyn gel mattress (very firm) and it fit with no problems. I wish it had some kind of padding for the legs though because I scratched my hardwood floor. I have a small bedroom so I was wanting this for extra storage space, but the ACTUAL CLEARANCE UNDERNEATH THE BED IS ONLY 11" so I won't be able to fit the bigger bins I was hoping, but my luggage set fits and I found underbed storage bins for some things.
