Was a bit worried about some of the negative reviews but glad I purchased based on the good reviews! Our not too old Memory Foam Matress was a bit too firm and my Husband was having lower back pain every morning! This topper is pretty soft and you do sink into it which cradles your body and supports your back. NO MORE LOWER BACK PAIN! Also, we were worried after 24 hours when the memory foam was still hard and bunched up in several spots! I was sick about thinking I would have to return it but after reading the instructions we kept it on top of our spare bed for over 48 hours and it was finally fully expanded. Maybe it took longer because of the bad packaging along with the cold winter temp. The warmth of the heater helped it along well. Glad I purched it and waited it out. I did place an extra matress cover over it to keep it in place so it does not move around anymore.

Decent Pillow-Topper. Nothing spectacular. Deep fitted sheets will not go over the mattress and topper. Topper constantly slides down with use. Original mattress too firm, so topper did help a bit. But has too become uncomfortable after 1 months use.

This is the perfect mattress topper for an air mattress. Adds a good bit of height and gives the air mattress some cushion. I’ve used it on both an air mattress (loved it) and on top of my regular mattress (not a fan). The foam gets very warm while sleeping when used on regular mattress. It’s comfy but almost too much cushion when used on a regular mattress. If you love a soft squishy bed, highly recommend! If you prefer some firmness, pass on this item.

I purchased this topper for a queen size bed in our guest room. The fit is perfect. There was no odor when I opened the foam layer. I noticed on some of the toppers people stated there was an odor, this mattress topper has none. You can put it on in the afternoon and have guest that evening and they will not smell any odors. I would purchase this product again if I need another topper.

I purchased this topper because the mattress I had was causing me to wake every morning with a backache. I decided to go for the 4 inch version to ensure I had the most comfort (even though the 3 inch was on sale.) After the first night of sleep, I woke up without pain. I've slept on this topper for about three weeks and so far, I have no complaints. It really does make the bed more comfortable. Now, a few other things you might want to know. The topper arrived in a cardboard box but it was only wrapped in plastic - the plastic was not completely sealed though which I found odd. The topper did have a bright yellow color on part of it (which some other folks have said looked like urine.) I am not sure why the color is only partly there but having the topper not completely sealed in the plastic bag made me wonder. There is a slight smell once it is opened up, but it dissipated pretty quickly. These things weren't issues for me, but if you tend to be particular, you might want to consider passing on this item. I just wanted a comfortable mattress topper and this fit the bill. (Mine also came with a zippered cover as well.)

Bought this a couple weeks ago and love it! Easy to add to our California King size mattress. So comfy and soft it's hard to leave in the morning . Was worried it would smell weird ( memory foam sometimes does) and be too hot- it isn't smelly or hot! I want to cover every bed in the house with these! Great price too!!

Has trouble with back sleeping on a traditional mattress and after reading reviews selected this. There IS a smell with the pad as with all of them but we started using it the first day and can heartily recommend it to anybody one. Price is better at Sam’s as I expected. So far it is working out great!

I bought this topper in hopes that it would relieve the back discomfort that my Mom had been experiencing every morning while trying to get out of bed for about 5 days. I had to assist her in getting out of bed her pain was so bad. After just one night, the back pain was gone and Mom was able to get out of bed on her own again! Alleluia!

I bought a Zinus 12” innerspring and foam mattress through Sams and found it was a bit firm, making my neck and back sore. Others said the same thing, so got a recommendation on a mattress topper snd chose the 4” Serta memory foam. Sleeps SO much better now.

I was skeptical about this product at first, so many of them have fallin short of expectations . I wanted a mattress topper that wouldn't go flat after a nights sleep and have to be re- fluffed for comfort. I am absolutely excited about this product, not only does it not go flat after use , but it is so comfy soft and springs back to it's original shape. I can't wait to crawl back into bed because I know I'm going to get a great nights sleep. love, love, love this product.
