I did a ton of research because this seemed like a lot of money to spend on a twin mattress. But everything I read confirmed that as far as responsible sourcing/production, Naturpedic meets the highest standards. The mattress and mattress cover arrived on time and well packaged. The mattress is for my 6 year old and she has absolutely no complaints. I prefer a firmer mattress and from my reading, I had the impression this would be on the firm side. It's a little soft for me and the edges do not seem reinforced-they do sag when sat upon. Overall, though, it feels very solid and well made and I am pleased with the waterproof mattress cover.
