Great buy
Got this for my son who has a loft bed. He likes the thicker mattress and it’s hard to find good ones that will work with a loft bed. Very comfortable for him. Offers great support and quality. It’s going to last a long time. This is actually the second one I have purchased since I got one a few months back for my other son who just graduated to a loft bed from a toddler bed.
this nightstand is great I bought it for my grand mother and she loves it –
Great quality product
This mattress is very comfortable and it came in the perfect size

Disappointing – wrong dimensions advertised
Purchased this mattress for a swinging day-bed. Hand-built the day-bed based on the dimensions stated here, 75x38x5. It’s very disheartening to find out that the mattress only expands out to 29 inches wide! Now, I have a huge 9-10 inch gap because it doesn’t expand to the advertised width.

I’m so happy with the quality and value

Good enough
It’s alright it was worth it for the price I paid. It’s kinda thin (but it is only like a 2 inch item) but it’s also like firm so I guess it’s got a lot of support. It’s easy to move around I think my son sleeps great on it, I added a cheap mattress topper from Walmart to kinda help it out a little, gonna need to get a thicker one I think. But it is good enough.
