      This mattress is super comfortable for those who like a mattress between firm and soft. It contours to your body perfectly. Mine had some dirt staining on it from the truck it was delivered by which is why I am not giving it a perfect rating. Another negative is if you use a colored sheet on the mattress it will also color the mattress… Which i’ve never experienced that with any other mattress.

    • WORST SERVICE - don't have my bed
      Verified Purchase

      I am moving and so I put my former home as the address and then when they called to arrange the delivery I asked to change the delivery address that was 7 days ago. I called overstock to get the address changed and they told me 48 hours to do so. Now 4 days later, no address change and the 3rd party delivery service can't change the address or get a hold of overstock to get confirmation of the change. it has now be 16 days since I ordered the bed. I have not bed to sleep on at my home.

      I wrote a glowing review for the queen size Brightmore I bought for my son. Liked it so much, I bought the king size for our spare bedroom. Cushion Firm is the perfect compromise between Firm and soft. Very supportive, yet has a cradling effect in all the right places.
