    New technology and eco-friendly, the Nature’s Sleep 2.5” 5 lb. density memory foam mattress topper.  It conforms to your individual shape to relieve pressure points. Imagine sleeping on your side and feeling pressure on your shoulders, hips and knees, then imagine sleeping on a Nature’s Sleep 2.5” 5lb density topper that supports all parts of your body because it conforms to your body weight and temperature so pressure is evenly distributed around your curves. Place this topper on your current mattress to make it a more comfortable nights rest, or on a mattress that is too firm. Can be used on a Sofa bed mattress to stop those bars from cutting into your back, or even placed on the floor when the kids have their friends over. A 300 thread count cotton cover (included) is washable, hypoallergenic and slides over the topper to keep it in place to protect your investment.  Made by using 30% Biopolymer, charcoal infused for anti-odor and mildew resistance and negative ion charged for improved sleeper circulation.

    Great Night Sleep
    Pros: very comfortable and easy to unroll and use
    "Actually, I bought one of these for each of my sons previously and finally got around to getting one for myself. I love it. It seems they have now added a mattress cover for it and that is helpful."

    Mattress does not measure up . . . literally!
    Pros: arrived quickly., no strong odor (it was in another room).
    Cons: the length is shorter than advertised., the width is shorter than advertised.., it does not come encased in a cover.
    Model Number: 425033MT
    "I bought this and unpacked it. I let it sit out for about 48 hours to expand. It never came within an inch and a half of either the advertised length and width of the topper (59.5" x 79.5" queen). So, I took it back and bought another. SAME STORY! I question whether the supplier is intentionally manufacturing and selling undersized mattress toppers. Being that it is not as advertised, I have not slept on it and cannot comment on that aspect of the mattress topper."

    Mattress Topper Comes Up SHORT (literally)
    Pros: didn't smell too bad., costco's return policy.
    Cons: the topper was not as large as the specifications., did not come in the cotton cover., picks up dirt like a sponge.
    Model Number: 425033MT
    "I received the topper and it was folded, rolled up tightly and then bound by a clear plastic wrap. The topper, at this point, is not in its cotton cover. I took the topper, laid it out on top of my pool table (so it would have a clean 'flat' space to air out and fully expand) and after 48 hours I measured it with a tape measure. It came up short of the listed size by between 1 to 2 inches on both the length and width. It was just a tad short of 2 1/2 inches deep. I phoned Nature's Sleep and was told that sometimes you have to wait a week for the mattress topper to "fully expand". Well, I'd already returned it to Costco and I will try this topper again, thinking that maybe not all of their mattress toppers are undersized. I'll see and I will update this review after I get my new topper. I wonder how much money Nature's Sleep could save if all of its mattress toppers were 'just a little' smaller than advertised, thereby cutting their cost of materials.
    Note: If you buy this or any topper which does not come in its cotton cover, make sure you place it on a very CLEAN surface, as the topper readily picks up any and all dirt until it is covered.
    Also, the box is not that heavy (as one review states) for a healthy, average sized adult."

    Very Disappointing Purchase
    Pros: very nice topper but was stained.
    Cons: the mildew odor was a deal-breaker.
    "I purchased this topper for our king-sized bed with the idea that it would help my bad back and provide some much needed comfort to my husband who has a terminal cancer and is spending more time in bed now. The item arrived in a timely fashion and I eagerly hauled the VERY HEAVY box into the house. Unpacking the box was a bit cumbersome as the topper weighed so much, but I was determined to get the topper onto the bed and enjoy a good night's sleep. However, the topper was like cold hard cookie dough out of the box and actually felt a bit damp. Undaunted, I spread it out over the bed and allowed it to spring back to it's true shape...which it did in about 20 minutes. The directions said to give it 24 hours before sleeping on it, and after noticing the cold, slightly damp feel of it, I gave it the full 24 hours in a room with a ceiling fan running full blast and and open window. The next day after checking to make sure it was dry and completely pliable, I slipped the very nice cover onto it and made the bed. I had trouble sleeping on it the first night, but attributed it to the new experience. The second night I noticed a mildew odor around the bed, but was too exhausted to investigate. The next morning I woke up with a stuffed up head and sneezing...a clear sign of allergies. My husband woke up and complained of "an odd odor." Further sniffing revealed that the mildew odor was indeed coming from the topper. I pulled the sheets and covers off and immediately flooded our bedroom with the smell of mildew. It was a few days before I found the help I needed to stuff the stinky thing back into the box and return it to Costco. The smell was absolutely intolerable and drove us right out of our bedroom. We have had an air filter running non-stop for days to remove all of the odor from the room. God bless the customer service people at Costco who took the awful thing back without question.
    I have had plain foam toppers on my beds in the past and loved the comfort they provided, but this has really soured me on trying another memory foam topper. My next purchase will be another plain foam topper at less than half the price of this one.
    In terms of comfort, I can't say that I was thrilled with this product, but to be fair, we only slept on it 2 nights.
    I also want to mention that when I pulled the cover off the topper I noticed an angular yellow stain on it that I hadn't seen when I first put it onto the bed. This may have been the source of the problem, but I am not willing to try this again. This was an absolute fiasco!
