First off, let me just say that this mattress took quite a long time to get here--over 2 weeks.The mattress itself is super comfy and a really, really great deal. And most importantly, flame retardant free. Just try to find a latex mattress anywhere else for this price.There were a few uneven holes in the latex--but it doesn't affect the quality at all and this may be how all natural latex mattress' look. We ordered a king---then sliced it in half and now have a 4" thick twin size mattress for my child's platform bed. It's actually comfortable just as is, but I may put a down or sheepskin topper on that. Price out a 4" twin latex mattress anywhere else and it will be at least a third more. Really great product and definitely worth the money!
