      This is like sleeping on a temperpetic mattress for much less than they cost. This is the most comfortable foam mattress I have ever slept on and I have tried several. I just wish it also came in twin size. EXCELLENT MATTRESS!

      We purchased this to go over the pads of the dinette in our travel trailer camper. It is firm and comfortable and has held up well. I am pleased with the quality of this memory foam mattress!

    • I agree! This is NOT memory foam!!!

      I agree with the two previous reviews. I have memory foam and this topper is definitely not memory foam. There isn't even a density rating for it on this website. I returned it. At first someone at Overstock said it wasn't returnable, but the returns dept. called me later and said it was ok to return. I've had several toppers and I thought this one was one of the worst. It kept me tossing and turning all night. For those who want to return this topper, Overstock told me to roll it up, tie it with rope and put it in plastic. I used twine and a jumbo rug bag from *** It took three teenagers, but we got it done.

      I ordered 3 toppers and this was best one. A little firm in beginning but became softer after a few days!

    •'s NOT memory foam! Just plain old foam...
      Verified Purchase
      Option: King

      I let myself believe the positive reviews and overlooked the couple negative reviews... SHAME ON ME! This is NOT 4 inches of memory foam, but a 3.5 inch cheap foam fused with 0.5 inches of blue memory foam. After purchasing a quality 4 inch twin memory foam mattress and a full 4 inch memory foam topper, I regret purchasing this one. It's going back, yet I'm not sure how... beware. Look closely at that photo!

    • Just a decent foam mattress - NOT memory foam
      Verified Purchase
      Option: Full

      After reading the reviews, I was ready for this to be a premium product. I have purchased other memory foam mattresses from (all Serta) and been happy with them. This is nothing more than a two layer/two density conventional foam mattress. I call it "amnesia foam" as it is definitely not (nor is it anything like) memory foam. I decided to keep it only because it was opened, which expanded the foam and made it impossible to return ship.

    Questions & Answers

    • Q:

      "How is this mattress topper packed?"

      • A:

        Folded into a strong bag, then packed into a cardboard carton, approximately 3'x3'x3'. Easy to unpack, unfolds immediately into a flat mattress, no kinks. Very comfortable, would buy it again.

    • Q:

      "Does this topper come in a queen size?"

      • A:

        At this time the queen size is out of stock.

    • Q:

      "What's the density? It doesn't say anywhere. Every other topper lists that. Is it 2.5, 3.5 4 or more?"
