  • Latex foam mattress

    Everything has been OK, except the shipping of the product. it arrived in quite a bad shape; carton was broken in many places. Took pics of everything, just in case (warranty is void if the mattress ahs any cuts)... thankfully, it was very well wrapped on heavy plastic, so the cuts did not make it thru tot he actual mattress. sleeping on it for a month by now, and no complaints so far.
