    For a 2 inch topper it is ok enough, but once we bought a thicker one, we were not as pleased with this one. If you like the thinner ones, you will like this one.

    I bought this for the queen size bed in my RV. I did not know there was a difference in sizes. I had to order another one. This one is very nice. Great feel.

    I searched and searched for the perfect price for a memory foam with the best density I could find. This product is perfect! I will never sleep again with out one of these! We just bought a camper and I am buying one for our camper bed. I highly recommend this! Also the gel keeps it from trapping heat and getting too hot while you sleep.

    The gel memory foam portion of the 2" king mattress topper is less than a 1/2 inch. Bag it arrived in was ripped all over, Zipper broke immediately upon inspection. The pad is not soft at all it is very firm. Wish I noticed the no return policy. Waste of *** dollars.

    I did not like this padirected at first. When you take it out of the packaging it is very thin. Within a coupl3 of days it expanded to what I expected. Very comfortable and happy with this purchase.

    Verified Purchase
    Option: King Topper

    I like this memory foam topper and 2" seems to be plenty thick. I debated whether I needed a thicker, more expensive one but am happy with this one. I also like that it is contained in a cover. I have had it out on my bed for about 2 weeks and I can still smell it. It is not a strong smell but I do hope it continues to dissipate.

  • Very satisfied

    Works well on our bed in rv. Adds just a bit softness to a very hard mattress. Have used only few times, so will see how long it lasts. Initially a good value.

  • Great topper
    Verified Purchase
    Option: King Topper

    We are very happy with our new bed topper. It came shipped in extremely well wrapped plastic and a bag that made it very simple to unroll. It's a little warmer to sleep on than I had hoped for but overall it's very nice.
