    Very good.

    If you want to save money on a memory foam mattress buy a bunch of these and stack them on top of each other. If you're stacking directly on a hard surface I suggest a minimum height of 7 toppers.if you weigh 200 to 250. They will need a little time to expand fully. But not a big issue. All of them work that way. I don't like the pre made memory foam mattresses that have all that junk in between the foam. Over time it pokes you. Just get straight foam and stack em. Also lighter and if need be you can always roll them back up. They probably won't fit in their original packaging after being used for a while but it is much easier to move around than a 30 lb mattress. They will stink for a while. That just the vocs in the foam. Ideally it's best to unroll and let them air out for a week or two. They will always have some sort of odor. It's just how memory foam is made.


    I haven’t slept on it yet so I can’t say how comfortable it is but I will say I have a queen bed so I ordered the queen size and it doesn’t cover the whole bed. It won’t cover where my head and feet will be so my advice would be size up if you want it to cover the whole bed.
    Thank you for your review. Foam mattress toppers are not made to fit edge to edge on a mattress. Once the foam has recovered from being compressed for packaging, there should be a 1 inch gap on each side when the topper is placed in the center of the mattress. If there is a discrepancy greater than 1 inch please you can return the item or call a Quality Team Member for further assistance at 1-800-BEDROOM, option 1.

    Hit it with steam.

    I bought this in store and when I got it home and unrolled it, I was immediately disappointed. It was so stiff and crimped there was no way it would fit a queen bed let alone the king I needed it for. BUT I had an idea. I have a small steam mop and decided to make a pass with it to see what it did. The thing blew up like a marshmallow! No creases, no smell and it is very fluffy. It even hangs off the sides of my king size bed. I would think you could get the same results with a fine mist of hot water from a spray bottle and then letting it dry. Anyway, Im very glad I didnt take it right back. It is so comfortable.

    Good comfort for low price

    I bought one and queen size and then three in twin size for my children's beds we have all been sleeping so much more comfortably plus these mattress toppers are just a little bit bigger than the size mattress it's made to fit so there's no weird ledge that is left on your mattress with any space I'm covered which is really nice the memory foam side of the foam mattress topper is not a very dense memory foam yet it still does the trick of making the bed is so much more comfortable I am a very heavy woman and it still does the trick for me and remains comfortable


    DOES NOT CONTAIN ANY MEMORY FOAM. Not as described. None of it is memory foam. Two non memory foam pieces glued together. Not 1.5 inches even after leaving it out to expand. One layer is barely 1/4 inch thick. The other layer is not even 3/4 inches thick.

    It is so soft and well packaged. Fit my bed perfectly. My bed was so hard now I can sleep better.


    I'd rate it 0 stars if I could. I bought this same one about 8 years ago and loved it. This one is horrible. It's crumpled up so bad that a week hasn't even straightened it out. It's not 1 1/2". The memory foam section is like a sliver, not enough to even feel it while laying down. The smell is horrible like a super strong glue that isn't going away. Horrible product that will be going back tomorrow!

    Well made and worth the price.

    This topper was bought to use an a futon I previously purchased from The futon is too hard on which to comfortably sleep, so the purchase of a topper was a neccesity. This topper did the trick. It is confortable to sleep on when placed on the futon. Additionally, Walmart's program to offer various merchandise on line with pick-up at the store is a great idea. The ability to purchase exactly what is needed when the local store does not stock the item increases one's experience with Walmart.
    Didn’t cover my whole bed, but, that didn’t matter. Pretty comfy. I like it.
    The memory foam combo mattress topper made such a great change is such a delight to sleep
