Happy with the quality for the money. Took me total of about 8-9 hours to assemble (over 3 days) and only required my husband's help for about 30 min of that. Didn't quite fit my approx 12.5" thick mattress, but I was able to modify the headboard as well as upper part to make it fit. (There's no reason the manufacturer couldn't make this adjustment on all units so it would accommodate more mattress thicknesses!!) Very sturdy sleeping surface. 
Only complaint was in the drawers... Challenging to put the drawer fronts on so the drawers would be evenly spaced and level. Redrilled a few holes so they would line up better. Simple solution that took a little futzing. Great space-saving solution in my secondary guest room!
