  • Good night sleep finally!
    Verified Purchase

    We have a firm Tempurpedic king size bed. Its too hard for me, but my husband loves it. I had to find something that would allow me to sleep comfortable in our bed. I am curvy and need my bed to fit my shape. A hard bed is horrible for me to sleep on. I went with this product and it was perfect! I felt like I was sleeping on a cloud. There was a minor chemical smell when I first took it out of the wrap, but I followed the instuctions to air it out and it was fine after that.

  • Good but liked the 3" better
    Verified Purchase

    Happy with my purchase but wish I would have gotten 3" size instead. It's hard to find sheets that fit. With that said, it's a great topper that definitely makes a mattress last longer and any bed more comfortable.

  • Two pieces
    Verified Purchase

    I didn't know there would be two separate pieces. They tell you to not pull them apart but I missed that step. I separated them and the blue piece ended up being a little bigger than the under white piece. Operator error. Other than that, it's very comfortable.

    Verified Purchase

    Ordered this and had some doubts and I'm glad to say my doubts have been put to rest. I LOVE this and the mattress cover fits over the memory foam AND my 16 in. mattress. Makes for a wonderful nights sleep.

  • Peaceful sleep
    Verified Purchase

    Because of hip trouble, my fairly firm mattress became too uncomfortable to sleep on. Finances tight so I bought this topper instead of a whole new mattress. Worth every penny! The mattress underneath gives support while this topper cushions and relieves all pressure points. I look forward to bedtime and sleep very soundly now. (I also own a sleep number bed, but this is better!)

  • soft
    Verified Purchase

    This topper is soft and you sink in so it took a week to get used to it. The "cool" layer helps but the topper still holds some heat which is why I didn't give it 5 stars. You will need deep pocket sheets so if you don't already have some, this is the perfect time to order some with the topper. I have bought toppers in the past for every bed in the house, for our motorhome, and even for my daughter's home as a house warming gift. This is the first one that came as 2 separate toppers with a cover. Years ago I bought the warehouse one - after more than a half dozen toppers over the years, Overstock still has superior products. Worth the money!

  • Gel Foam Mattress
    Verified Purchase

    It is definitely comfortable, but does not fit the cover nearly as well as it looks in the photo. You will need deep pocket sheets. It is harder to hang over the edge of the mattress now. Also didn't like that the package did not come with any instructions for filling the cover, nor did it mention anywhere the brand. So, I have to assume I got the one in the photo. I recommend with some reservations.

  • Excellent memory foam topper
    Verified Purchase

    I've used this memory foam topper for 3 months and love it - so much so that I am now purchasing a twin size for a nursing home patient in my family. I hope it helps her with her arthritis pain as it has for me. It holds it's shape well (at least so far) and the cover is easy to put on. I initially ordered the 4 inch big bump topper and was surprised to receive something that would not support or absorb body pressure. Needless to say this immediately was rewrapped and went back into the box before it could expand.

    Makes the bed feel like it's hugging you. Very comfortable. My husband didn't think he was going to like it but he has slept better since we put it on.
