Latex Tips:
Remove from packaging within 72 hours of receipt to maximize latex expansion. This product arrives very tightly packed. Unwrap and allow 48 hours for this product to return to its original shape. Being sealed in plastic packaging sometimes traps odors. After unwrapping, allow product to air for a few hours. Due to machine-cutting manufacturing processes, there may be slight variances in the dimensions of this product.

Due to the nature of latex, the firmness level of every item is unique. Please be advised that even similar products may produce different firmness results.

    No noticible outgassing after weekend plumping. Nice cotton cover. Thought it was all latex/ fooled me. Soft feel on joints yet Somewhat firm support on firm model. my VERY BAD BACK likes it WAY better than models with less than 3 inch latex or memory foam

  • Only 55% Latex & very soft
    Verified Purchase

    According to its tag, this mattress is 45% polyurethane foam, and only 55% latex. Since we bought it to avoid off-gassing, that ratio wasn't going to work for us. It was also extremely soft-- soft enough one sank down all the way to the box spring.

  • Terrible, not what it says
    Verified Purchase

    This is not a latex foam mattress as it was described to be. I had to call the company to find out that there are only 3" of latex foam, with 8" of polyurethane foam underneath it. It makes an indent that doesn't pop back up, almost within 3 or 4 nights. Very uncomfortable. If you want latex foam, this mattress is a waste of money.
