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.

We purchased this on hopes to mimic the bed we slept in on a recent vacation. It for sure is very lofty and are satisfied with the description and what we received. Purchased a queen (vacay bed was a king)..that may be where the problem lies. The insert on initial lay down for the night is quite luxurious. I read in bed and looked forward to my time in the bed sinking into my read and softly sinking into the bed! BUT, once going to sleep for the night and once my husband was in bed too I found myself spending the whole night readjusting myself. I was being pulled into the center leaving 1/2 my body in squishy paradise a d the other half in luxury softness. It sounds minimal but just like you can tell if one foot is covered and one foot is uncovered (and you're not looking for "heat relief") its very bothersome. I think (for me) this works if you are alone (in any size bed) or you are sharing a king size bed..those beds are so massive it really is like having your own bed right next to each other. We are average people. 5'7" and 5'11", with normal weights. He is 180 and I am....less (haha). As for the foam being warm..yes, i would say it does make your sleep warmer...but for me i could have dealt with that, its the unlevel feeling from one side of body to other that i couldnt get past. We had this on our bed for almost 4 weeks. I spent several nights moved to couch. I woke up all the other times groggy and unaligned. I REALLY tried to adjust to this. We have removed it and actually cut it down to fit my daughters twin size bed. The verdicts still out. Her first morning actually, yesterday) was not a huge win, we'll see today. I will say its not causing her to wake up any earlier (like me)...she's still a teenager!!

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!!!!

It has such a chemical smell. I have a sore theoatbwithin fifteen minutes of being in the room it’s in. I keep the windows open but I’m going to have to put it out in the sun. It’s super comfy but I m very sensitive to chemicals and it’s really bad for me. Was very disappointed in that. I have mattress toppers in our camper and they don’t smell at all from a different company. But they don’t make sizes for beds in homes.

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!

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.

Fantastic product. I wasn’t expecting it to come with the fitted sheet cover with a pad as well, it is so soft. If you need a firm bed this is not for you, but if you are comfortable melting into your mattress this is the one! I sleep so much better now.

I sleep good every night now!

A week later and hasn't expanded

This mattress topper is so comfortable and i did not sweat it kept me cool and comfortable all night. I highly recommend it.
