Bought this for my kids bedroom. Using the trundle for storage which is fantastic.  For reference, I fit 3 underbed boxes inside the trundle and could fit a 4th. I wouldn't put anything heavy in it. It's mostly nerf guns, rackets, etc. 

The slates for the queen mattress don't seem too sturdy. My kids love jumping on their bed (8 and 6) so they are a little disappointed I told them they can't do it on this one. 

The mattress we already had goes quite high, so it's not really a daybed. So just be mindful of the mattress thickness if you are buying a new mattress for it. Overall satisfied with the purchase. 

Used Handy and the service was fantastic.
