Is really 3 inches before the added mattress cover and you just sink in it. In addition it was slightly wider than the bed so is very hard to put the sheets in it. Would return but is impossible to pack into a box. Sorry I ever purchase this product.

the mattress topper pad slids off the bed. Every morning have to remake bed to get pad back where it belongs. It bunches up and you are continully trying to get comfortable thru the night. you cannot just roll over you have to lift yourself up or it moves with you. My lab even quit sleeping in the bed since putting on this pad and he has slept in our bed for 5 years.Would not recommend this product and going to return on next trip to Sams Club

Bought for my son, so glad I did... he’s a bit heavy and his mattress was starting to sink in...this brought his bed back to life and he loves the fact that he’s sleeping more comfortably and the whole night.... great product. Will get a king for myself...

I was having hip pain, and slept in a soft bed and woke up pain free. This topper has helped to make my mattress softer and much kinder to my hips. Reasonably priced solution to a new mattress. Also, the box arrived damaged, and the memory foam was torn. The return process was very easy in store. Once I got it in the door they took care of me from there.

It saved me a new mattress purchase for now. My back pain has gone away from the mattress no longer supporting my 220 pounds. I can also sleep comfortably on my back for the first time. JUST REMEMBER, never sleep on these things until you allow them to vent or release all the toxic chemical odor they release upon opening. They are plastic/rubber in composition after all. We didn't sleep on it at all the first night. Left it extended in spare bedroom with windows open. We aired it out for four days before the odor was tolerable. Other than that, I'm a happy camper.

Purchased this three weeks ago for my 93 year old mother. It is an extremely good value for the money. Looked at numerous toppers before purchasing, and most 2" toppers were more expensive than this product and not better made. Mom loves it and sleeps like a baby!

I bought one of these a few months ago and wow was it sooo comfy like sleeping on a cloud. So I bought one for my son who has damaged nerves in his legs and wakes up constantly from the pain, he has been sleeping soundly through the whole night since he got it. Then I bought one for my mother-in-law who has arthritis and suffered from restless nights, she too is now sleeping comfortably all night long. Both say they are also sleeping on their backs instead of their sides now too. I suggest opening it on your bed, there is absolutely no smell and you can sleep on it within an hour or two.

This topper is so soft and comfy. No odor whatsoever. This is the second mattress topper I bought. The first one was $15 cheaper. I thought I was being money-wise and saving a few dollars for the same thing. Not so. A month later the first one still had a terrible odor. I returned it and bought the Serta 4" topper instead. No odor from the first night! I couldn't be more pleased. DO NOT try to save fifteen bucks. By this one instead.

We have relatively new memory foam mattresses, split-king, which were on the lower priced side. I originally bought this only to cover the gap in the split-king. But this topper is amazing!!! I usually toss and turn quite a bit, but after putting this on the bed, I turn maybe once a night now. My wife and I are getting more REM sleep as we are both experiencing more dreams since using this. Our bed is now the most comfortable bed I ever slept in. It really is a joy to slip into bed each night. I recommend this topper to everyone, 100%.

Let me start with, I have never written a review of a product before. This was such a great buy, I had to comment. I purchased this Serta topper for a guest bedroom. I ordered the king. This mattress pad is more comfortable and made better than the Temperpedic topper I have on my personal bed. I paid $400 for the 3 inch Temperpedic pad and $180 for the Serta. The Temperpedic is nice, but nowhere close to the Serta. I highly recommend this Serta topper. You will be so happy you got this wonderful topper. As a side note, I have ewncouraged 3 close friends purchse this topper in the past 3 months and they love it.
