We got this for our daughters trundle bed. 

PROS: Fits in the trundle frame, feels pretty comfortable for the most part. 

CONS: Inside the box was a note to unpack the mattress wishing a a day or so of receiving. This information would have been a lot more helpful printed ON the box, as we didn't rush to unpack the mattress since we didn't know we had to. As a result I'm guessing, the corners never really expanded to their full height. Since it's a trundle bed though and won't be used much, this isn't a big deal for us. 

Also, I feel like the listing photo makes it appear as though this mattress is thicker than what it really is. This mattress will make a great bed for a trundle bed or maybe a child's bed, but I wouldn't recommend it for a guest room or primary bed.
