As a late 70 year old Great Grandma, with aches and pains everywhere , I couldn't get a good nights sleep on my 15 year old mattress and topper. At this time I couldn't afford a new mattress, So I wanted to give this a try. So very happy I did. I opened my package and let it expand as directed, I put the pillow top cover in the dryer and fluffed it, and with a little bit of effort by myself I put the cover on and then put the topper on my bed. I am being very honest here. I got the first 8 hr, good nights sleep, that I have had in years

The new bed we purchased 6 months ago, is just right for me and to firm for the wife. We are always in Sams Club and noticed this Seta Matters Toper. We have a king size bed and purchased this one. It fit exactly right and we BOTH had a wonderful night rest. The king size was $ 179.00 and worth it. I would recommend buying.

I have used Serta mattress toppers for probably 15 years. They have always been wonderful and lasted many years, until now. The new gel foam toppers are not the same and do NOT provide the support that regular memory foam does. They crush down to the surface below the topper, and if you have any kind of joint ache, will not help; in fact seems to make it worse. Don't waste your money on this.

I bought this to put on a brand new firm mattress to aid in breaking in the mattress. It is super comfortable but crazy hot. I was hoping to enjoy it more with the cooler weather but I still wake up very hot in the middle of the night. It would be 5 stars if not for the heat retention. Freeze babies will love this.

This mattress topper is amazing. It has 2 parts a 4 inch memory foam and then a pillow topper cover to go over the foam. This is my second one to purchase for my second daughter to take to college. They say it makes those awful dorm beds better than our nice mattresses at home!

Arrived today from FedEx, took out of package and had HUGE stains all over it. After over an hour on the phone with "customer service", maybe someone is coming to pick it up? Was so excited to try it - with those stains, absolutely NOT. And "customer service" was laughable....

We have used this for a month now and although it adds a lot of height, and I have to buy all new sheets, I do like it. It does feel as if it is crushing more in the middle and on the side my boyfriend sleeps. I will be measuring crush depth soon. Customer service is easily accessible and promote with replies. The mattress pad included is nice but not as padded as I expected.

Got the first to augment a shallow bunk mattress on our new RV and man what a difference it made. I'm 6'2" and 225 lbs and even in a 6' bunk space I sleep like a baby on this thing. I tend to sleep hot, but the top inch of pillow top breaths enough to make it relatively temp neutral. Not quite to the point of my Purple mattress at home, but it is still comfy all the way around. This purchase is actually a second one to put on another sleeping spot on the RV as well. Have even thrown down on the floor for sleep overs and kids sleep decently on it as well.

This is very comfortable. Not too firm, not too soft. It made my 20 year old mattress feel new again. However, this topper is made in 2 parts. There's a 3 inch foam piece and a 1 inch piece in a cover that you zip over the foam piece. Unfortunately, the topper slides around on the mattress when the cover is on (despite little plastic dots that I assume are supposed to grip), so I had to unzip it and just set the 1 inch piece with cover on top of the foam piece. The foam piece does not slide around on the mattress, but the loose cover with all the fabric bunches up in places. But that's better than having the entire topper slide several inches off the side of the mattress every night. Overall, I'm very happy with this topper. Very comfy. My back doesn't hurt anymore and neither do my hips, so all is good.

SMELL: Yes, it has a chemical smell. It took 2 days in a ~90 degree garage for the smell to fade to almost nothing. It was a 2 car garage and within few hours the entire garage had a strong smell of the foam...so, if you can, air it outside of your home. DENSITY: I accurately weighed and measured the foam. The density is 2.74 lbs which is considered "low density". Don't expect to press your hand into the foam and have that image stay for more than a second or two. If you want that kind of foam, buy a latex topper of at least 6lb density. QUILTED COVER: No complaints. It's looks nice, it's soft and had no smell after washing it. It adds very little in the way of padding. FOAM COMFORT: This was for a 160lb person and it met their needs. The heavy parts of your body will compress the foam flat while the less heavy areas (neck) will receive gentle support. This is not a gel foam, so there is no cooling effect. It will retain heat rather than dissipating it; so plan on a few degrees warmer under the covers. SUMMARY: This a good quality, low density, foam product that will soften up a little too hard mattress.
