The odor is very strong, burn your eyes and make throat sore strong. After keeping it opened up in the garage for a week we brought it inside. Odor still very strong but better. I think we are about 5 weeks into using it and it still smells but not terrible. Maybe it will totally dissipate, hope no health risks involved with the odor. I probably should have figured out how to return it. It also scoots around on the bed, I have to pull it back even on the edges every couple days. Too expensive to just throw away. If I had it to do over I would have paid more attention to other reviews about the terrible smell and done something different.

I have bought this before at Sam’s and never had a problem, but this one smells terrible like strong chemicals, so disappointed, I’ve tried the baking soda process, airing out, nothing works, I have terrible back problems, and was hoping this topper would help, but the smell is so bad I can’t sleep on it

I love love love this! It really IS THE BEST memory foam mattress topper! Made of high quality materials, this is actually two pieces in one. The memory foam mattress topper and a 1" soft pillow top cover that fits like a glove. Feels like sleeping on a cloud, this cradles my son's body like nothing else. He has suffered arthritic hip pain and this has been a godsend. After only a few days of use, it's a miracle. No more pain meds, no more regular applications of Ben Gay. If I could give this 10 Stars, I would. Thank you Sam's Club and Serta!!!!

We purchased a Tempur-pedic over a year ago and made a mistake…we bought extra firm, but due to age, our bodies no longer “like” to lay on a firm mattress. The addition of the Serta “4 inch mattress topper” has certainly helped with that problem. No hesitation, I would purchase again!

If you are in the market for a memory foam this pillow-top and memory foam is an excellent way to try it before a much larger commitment. As many reviews say, it takes time to get used to this topper. I learned to like but my husband never did. Nevertheless, this is an excellent value.

I LOVE this! I sleep like a rock! My back ache is gone. My quality of sleep is greatly improved. The dog has started going to bed early to gain better position on the new mattress topper. LOL I bought a second one for the guest bed and my visitors have also enjoyed it. Worth every penny!

So we used this in our camper to go on top of the very thin and sad camper mattress. We have only used it for 3 nights, but it made sleeping soooo much better! Some reviews said it made people hot, we did not experience that and my husband and I like a cool sleeping environment. As far as smell, we laid it out on our spare bed about 5 days before use, there was a slight chemical smell in the room(almost like new carpet would smell) but when we put it in the camper 5 days later we did not notice it at all.

I have a 29 yr old Sleep number bed, and at one point it had a plush top that is long gone. Everything else on the bed works great so we have opted for Mattress Toppers. The one I have on there is very firm. Hurts my hips as a side sleeper. So I ordered this one. It is ultra soft! My husband and I both feel like our legs are elevated because of how much we sink from the hip area. But I have had some of the most restful sleep since putting it on the bed. If you like sleeping on a plush or very soft bed, then I recommend it highly.

This is our second Serta topper. It has made two over firm mattress is just perfect. I suggest this topper to anyone looking to fix a bed that is too firm. It doesn’t help with a slope in the middle, which means you need a new mattress. However, you can buy a coil/memory foam mattress that isn’t too expensive, in a firm, and add this topper to make it just like a mattress costing several thousand dollars.

This topper is just wonderful! I bought a new mattress about a year ago, and it was hard as a rock. I was waking up every morning with aches and pains, especially in my hips. The topper is squishy, and very comfortable. Even my husband likes it, and he informed me that his knees have stopped hurting in the morning.
