Wake up feeling refreshed and free of aches and pains with this twin-size mattress from Serta. This memory foam mattress eliminates pressure points and adjusts to the shape of your body, reducing disturbances that cause tossing and turning. The breathable cover ensures air flows through to keep you cool even as the temperature changes while you sleep.

  • 2-inch memory foam comfort layer
  • 6-inch premium base layer for superior support
  • Distributes body weight better than traditional inner spring
  • Relieves painful pressure points
  • Holds its shape, no flipping or rotating required
  • Breathable cotton cover
  • Use with your existing box spring and frame, or platform bed (with no box spring)
  • Eliminates motion transfer between you and your partner
  • Improves circulation
  • Dimensions: 8 inches high x 39 inches wide x 75 inches long

Memory Foam Tips:
  • Remove from packaging within 72 hours of receipt to maximize memory foam expansion
  • This product arrives tightly packed in a box sized to be portable; once you unwrap it, you can sleep on it the same night, although it may take 48 hours to return fully to its original shape.
  • Memory foam is inherently comfortable and supportive, no matter how firm it feels; similar items can vary in firmness due to the nature of the foam
  • Product is vacuum sealed at the factory for efficient shipping; vacuum sealing sometimes traps odors, but once opened, a few hours of airing will usually remove the odor
  • Due to machine-cutting manufacturing processes, there may be slight variances in the dimensions of this product.

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

    • awesome nights sleep
      Verified Purchase

      My first thought was , this mattress is too hard. But after 3 night of sleeping on it, I have to say it is the most comfortable mattress I have ever owned. I did put an additional 2 inch memory foam topper on top. So if I ordered another, I would order the 10 inch, which is 8 inches of foam and an additional 4 inches of memory foam on top. Then I would not need the additional topper.

    • decent and comfy
      Verified Purchase

      I purchased two of these for a day bed + trundle and they worked out perfectly. The name brand is actually a bit misleading because it's a mattress made by Sleep Innovations being sold by Serta under the Serta brand (the packing documents make that clear). That said, the mattresses arrived tightly compressed in two big 2'x2'x4' boxes, were easily unpackaged, decompressed, and allowed to air out for a couple days before getting used. There was a strong odor at first, but it dissipated. They are very comfortable mattresses so I'm hoping they stand up well over time. The only negative that comes to mind is that the mattresses do not have reinforced edges so there's not as much support if you're sitting on the edge of the bed. Many mattresses lack this feature until you spend a little more, though, so it's still a great bargain and a simple compromise. Moreover, the lack of edge support actually works out great, possibly better, for popping up the trundle and making a "short" king out of the daybed without having a hard seam between the two mattresses. In all, a great deal and comfortable mattress.

    • light & comfortable
      Verified Purchase

      After a lot of research and seeing a lot of poor quality spring mattresses in the $200-400 range, we bought these for our kids' bunkbeds- I am so glad we did. They are light- so easy to lift onto top bunk, but just as comfortable as the brand name memory foam mattress we have for the grown ups in our house... Our kids are very happy and tell us that they think the bed is really cozy. Since our kids are still little we have put a mattress protector under the sheets, but they don't seem to notice. I have taken a nap on one of the mattresses and founf it to be very very comforatble. The boxes arrived in less than a week (UPS) and we opened them immediately to let them unfold and "off gas", and set them up the next day. Overnight the light smell had dissipated and the mattresses were completely uncurled. We are very very happy with our purchase and will consider these mattresses again- they are not cheap, but much more affordable than Tempurpedic and lighter as well. We think they are worth the price.

    • Nice Product
      Verified Purchase

      I have ordered it for my son's bed. The item was shipped on time and it arrived in good shape. The Box has the Serta label but the original manufacturer is Sleep Innovations. I am very impressed with this product. After sleeping on it, I slept through the night after a very long time without much tossing and turning. It is firm but the Gel component of the mattress makes it very comfortable.

      The only thing I might've done differently would be to have chosen the 10-inch Serta Memory Foam mattress. I had wanted to be sure my fitted sheets would work well, so chose the 8-inch. A wonderful night's sleep!
