      We have purchased different toppers over the years, but right away we noticed the difference on this one, and it was all for the better! If you are a “hot” sleeper (as we both are) you will notice right away that you are roasting like the standard memory foam mattress toppers. And the comfort factor is out of this world! I can’t believe the difference.

      Option: Queen

      I wasn't quite sure how it would feel with the egg-crate style as my last topper was flat, but this is way better. I feel like I'm being supported more fully as a result of the design. Also, it is infinitely cooler than my last topper! I no longer feel like I'm sweating to death. Great solution to purchasing a Tempurpedic or other expensive memory foam bed.

      Option: Queen

      This is our second 4-inch gel memory foam topper. The first one had the smaller bumps closer. It lasted 1 1/2 years so that was great for us. We decided to try this one and we love it! I would recommend this to anyone who likes to keep cool and likes the memory foam toppers. It's good for back pain support too. Low odor disappears after airing out for a few hours! We slept on it the same day it was delivered!

      Option: King

      Wow. Just wow! It really does have good density in all 4in. of memory foam. The big bump is a more fluid method of redistributing pressure away from the body, even more so than just the egg crate design. I am not the least bit disappointed. I will also say as to the temperature aspect being all it is claimed to be, as I write this, it is the beginning of winter and I do feel very snug and warm without the aid of my electric blanket yet. When hotter temperatures come, that will be the test of complete satisfaction and hopefully (being new to giving reviews on overstock) I can do a followup review as to the level of comfort that this mattress actually provides. Love it!! and really Great Price ... Good quality for great value. Thank you Overstock for everything! Couldn't be more pleased.

      This topper did the trick to improve the comfort of our camper mattress. No more tossing and turning or waking up with sore backs and hips! We like it so much that we put it on our regular bed in the house after camping season! Great quality and price too! Very happy with this purchase.

      Comfortable and cool if you like a swishy surface. Be careful moving it, because it will tear if not done properly. I love this product. We own several. Extends the life of a mattress.

        Yes I put my mattress pad cover and fitted sheet on top of the topper.

    • Q:

      "Does this keep you cool? I've been reading comments of them all and some say ya and some say no? I get extremely hot so I need a cooling one. If not this please leave suggestion! Thanks "

      • A:

        This particular mattress pad does not have cooling gel technology. It is very comfortable but does make you a little warm. I hope this helps.

      • A:

        We bought this 4" topper and LOVE IT!! Keeps you cool, helps with tossing and turning less. And when you do move, your partner does not feel you moving. Highly recommend it!

      • A:

        I had this same concern when I ordered this mattress topper and was why I did not order one of the solid memory foam type. I have not found this topper to be warming. We have enjoyed sleeping on this pad for approximately 6 months.
