      This was one of my best buys. Revived an older mattress at a much lower cost than replacing it. Great way to save money at our beach house and make sure everyone has a good nights sleep!

      This mattress came compressed and inflated rapidly with little to no odor normally present. It conforms to my body and I have honestly slept better than I have in a long time. In fact it is so comfortable, my dogs have decided my bed is the place to be 24/7, which leaves little room for me !!!!!!!!!!

      This topper is very soft. While I prefer one between hard and soft, people with sore shoulders will find this comfortable. You may need another mattress underneath for support.

    • Out standing Memory Foam
      Verified Purchase

      Best one we have had yet. Purchased the 4" king size foam and love it! This is the third Memory Foam purchase we have made from Overstock. The first two were 2" and 3" and great ( still in use on other beds)....but this has the other two beat hands down. It arrived in a timely manner, with no smell and exactly the rigth size. We could not be happier. The 4" makes it a little more difficult for shorties to climb onto the bed...but once you get there you don't want to floating on a cloud. If anyone is on tge fence about buying this size Memory Foam...don't worry you will love it.

    • 4 inch memory foam mattress topper
      Verified Purchase

      This is my first topper, so I really didn' know what to expect. I have hip pain and my mattress is too firm, so I bought this to soften it up. I didn't notice any smell after I aired it out according to the directions. I have no complaints as to the delivery, it came very fast and in good condition. The only problem I have with it is that it seems rather soft for a 4 pound density, because I sink into it and it is very hot. I have 3 mattress pads on it and it is still hot. I also have a hard time turning over at night, but was thinking that was because I am a heavy person. This topper helps the hip pain, so I will give it 4 stars.

    • mattress relieved back pain
      Verified Purchase

      the product arrived in a generic box and, i cannot affirm the mattress was what I ordered. :-( The mattress itself is working miracles for low back pain. Foam has a learning curve for turning and rolling, but one gets accustomed very quickly. I had no problem with any kind of odor. So far, very good. I am happy with the purchase and if it lasts as long as expected, I will be super happy.

    • Q:

      "i currently have a slumber solution high loft 4in, 3lb mem foam topper. I like it .but am also considering buying a slumber solution 4in 3lb flat mem foam topper. is there much difference in comfort levels? what is the difference besides appearance?"

      • A:
