    • Not Serta Brand
      Verified Purchase

      This mattress does not say Serta on it anywhere- it actually has a different brand name on it all together. Makes me question OverStock for listing this as a Serta mattress if you cannot back that up. Disappointed because of course there is a no return policy if the mattress is opened. So make sure to check the paperwork inside before you open the mattress. The mattress is decent, its memory foam and comfortable (very firm) but I question everything about the listing now because the brand name is not present. Is it really antibacterial? Is it really foam? Is it really under warranty? Not happy with the misleading and false info in the listing.

    • Worst nights sleep
      Verified Purchase

      Bought this mattress based on the great reviews and sincerely regret it one week later. This mattress is as hard as a brick. My back aches every morning when I wake up. I have no idea how it can be considered memory foam when it feels like sleeping on concrete. Wish I could return it!! Don't waste your money on this

    • Great Mattress!
      Verified Purchase

      My husband and I were leery of purchasing a mattress online, so we went to a few different mattress stores to try them out first. I couldn't find a Serta Deluxe in any of the stores but we found similar styles with the same descriptions and material make up. We received this mattress one day ahead of schedule and laid it out that night. It came rolled up in a box which made it easier to haul up 2 flights of stairs. We didn't sleep on it that night because I had read some reviews about letting it air out. I can't even begin to explain the relief of back and hip pain that I had even after the first night. I am pregnant and never thought that a more firm mattress is what I needed. My husband and I are both side sleepers and this is perfect. It's soft to the touch but firm where it needs to be! I would HIGHLY recommend trying mattresses out in the store before you purchase it online- considering it's not returnable once opened. This is a great mattress, especially for the price.

      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.

    • 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.

      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.

    • 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.

    • Comfortable from the beginning.
      Verified Purchase

      Fast ship on wonderful, comfortable mattress. Can't stress strongly enough what a good deal this is, and what great quality the mattress is. Puffed up almost immediately, no odor, easy to handle. Will buy a queen sized one for our guest room when it's in the budget.

    • Q:

      "I have an existing box spring (1.5 years old) I'd like to use with this instead of buying something new right now. Someone recommended putting a sheet of 1/4 perforated plywood on top of it to help support the mattress. Is this a good idea?"

      • A:

        Yes you could do that. That would work as a platform.

    • Q:

With the proper foundation, the mattress will not sag and is protected with a 20 year warranty from Serta.

    • Q:

      "what are the shipping dimensions? does it come in a roll or folded in a box and if so what are the dimensions of the box I need to know this because I need to travel with it once it arrives"

        The approximate box dimensions are 41 inches high x 20 inches wide x 24 inches deep.

    • Q:

      "what does the 20 year Limited Manufacturer warranty cover?"

      • A:

        The warranty covers any sagging or permanent depressions of an inch and a half or greater and any defects of the foam.

    • Q:

      "I see nothing about a firmness rating in the specs - how does this mattress rate for softness/firmness? Seeing as it's nonreturnable, I need to get it right the first time."

      • A:

        We do understand firmness rating is very important when ordering online. This item features medium support.

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.

      • A:

        Thank you for the question beeno01. I am sorry but we do not have the information to compare the two mattresses together. This particular mattress has received very favorable reviews. 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.

    • Q:

      "does this mattress come with box-spring bases?"

      • A:

        Thank you for shopping with us prodgers35. This does not come with a foundation. Here is our selection of mattress systems. http://www.overstock.com/search?keywords=king+mattress+with+foundation&SearchType=Header Have a great day.
