Product is fantastic, it took me over 3 months to find the "perfect" mattress, finally settling on this by making an executive decision over the missus!
Daughter sleeps fantastically well, its perfect for the top bunk, am going to get one for the bottom bunk as soon as I finish this review. The mattress did come a little damaged, but their customer service took care of it as soon as I let them know about it, they were brilliant! Hopefully the second one doesn't come damaged!
It does come rolled up though, delivery wasn't great, they went to the wrong address initially and couldn't deliver for another 2 days after, which was a pain, but that has nothing to do with this company's as delivery is outsourced!

Its perfect for a bunk bed especially the top bunk as that was our main worry, but even for a single mattress, child and adult alike, this is brilliant, i have had a sleep on the mattress, ever so comfortable!
