      After reading other reviews on this mattress, I took the advise of 1) unboxing it in the room and 2) propping it against an open window for one overnight to eliminate the odor; both excellent suggestions. The mattress is all you could want for comfort and design. As it is new, I cannot give any hints to longevity, only to a much better sleep and night.

    • Great!!
      Verified Purchase

      Phenomenal mattress, best purchase ever. It has been two months and we are still so happy with it. It expanded great, and there was actually no smell for us like some other people complained of.

    • Much firmer than I expected!
      Verified Purchase

      After sleeping on a mattress that was way too soft for years, we decided to buy one that was firmer. This mattress is very solid once it opens. It gives a little, but it's still much firmer than I expected. We will need to get a topper to soften it a little. It has good support and it's a great base, but I want a little more give on the top. It does not transfer motion and I can't even tell when my husband rolls over or gets out of bed. I was pleased to see that it was manufactured in the town I live in. Delivery was super fast.

    • Great mattress...a little too firm
      Verified Purchase

      This mattress is great. It arrived in 5 days after ordering it. It is the perfect height for our platform bed without a box spring. It has a lot of support but is a bit too firm. It's hard to buy a mattress online without testing it first! I thought the memory foam might soften up a little after a while but it didn't so we went ahead and bought a cheap memory foam mattress topper and put that on which made the mattress perfect. There is a lot of support from the mattress and the pad on top adds the perfect amount of cushion. Considering you can buy the same mattress on Amazon for **** more, I think this was a great deal and would absolutely recommend it.

    • Excellent value!
      Verified Purchase

      Love our new mattress. We've had it fur there weeks. Hubby was hesitant to break from the traditional box springs and mattress, but there's no looking back now! We're both over the moon with our purchase. I wasn't sure how we'd get it up the small staircase, turn down the hallway, and unti out bedroom, but it was packaged in a compact box and was easy to maneuver. Directions say to let it unroll and rest 24-48 hours before sleeping on it, but we broke that rule and all is fine. It's firm, supportive but not hard at all. Unbelievable value!

    • Best decision made
      Verified Purchase

      I was skeptical about buying a mattress online and let alone a memory foam mattress for the fist time! I am pleased I did. The Serta 12-inch Deluxe Memory Foam Mattress arrived on time and very easy to set up. My husband and I lay it on the platform frame and left it alone for the 72 hours as specified online. Our mattress did not have a strong odor as some other reviewers mentioned. The mattress is firm, but very comfortable, I had a pillow top which would cause my husband and I a lot of back and shoulder pain every morning. Both my husband and I have had restful nights with no pain. I am glad I purchased the mattress.

    • GREAT MATTRESS
      Verified Purchase

      This is by far the best mattress I have ever slept in! I have seven herniated discs and one fractured (healed) vertebrae in my spine. Switching to this mattress was the best decision I made for my healing process and to alleviate as much pain as possible. We have owned the mattress for two years now and it is still in excellent condition, it isn't sinking or wearing at all! The only issue is it is hot (menopause). This isn't an issue for my husband though. I highly recommend this product!

Really don't want that."

      • A:

        Hello Mike, memory foam does tend to retain body heat, if this is worrisome for you, then i would suggest going with a memory foam mattress that has gel, which will help to keep you cool.

I looked on other sites and can say that the Pierta also got favorable reviews especially when talking about heat dissipation. I am sorry I couldn't answer the question. Have a great day and thanks for visiting our site.
