Im not a "natural" person or anything. I've had toppers before that had chemical smells, they all went away after a couple of weeks. This one? OMG. TWO months and it is STILL smelling very chemical-like. I give up... the headaches are constant and it's caused a couple of mild asthma episodes. Luckily, Sams will take it back. Glad they have a decent return policy.

I bought this in November and I hate it. My back is aching, my hips hurt and I do not look forward to sleeping any more. I am in pain. I wish I had kept my old cheaper memory foam topper but it was starting to shred. More expensive is not always better.

We’ve had two other memory foam toppers and they aren’t even close to this one. I’m laying in bed as I write this review, and I haven’t been this comfortable in years! I have back and hip issues, and the past few months have been miserable. I didn’t look forward to going to bed because I knew I was as facing another long night of tossing and turning trying to find a comfortable sleep position. My husband and I put this topper on yesterday and I was praying this would be a solution. I woke up very well rested, and the sheets and blankets aren’t totally destroyed after constant rustling around all night. I’m sooo glad we chose this one! Looking forward to many more restful nights sleep ahead.

I have been using the Serta 4 inch memory foam mattress topper for many years. I bought them for my sons dorm bed too. I am currently moving and will be leaving my king size bed with topper to my son and daughter in law (they are super happy) I’m downsizing to a queen sized mattress. The best thing about it is I know I don’t have to go spend a ton on a mattress because I have seen this Serta mattress topper turn the oldest, hardest mattress into a sleeping heaven!! They have saved me thousands of dollars on new mattresses, just by adding the Serta topper to the old mattress. I will never own a bed without this topper. Looking for a nice gift to give someone?? This mattress topper will last them for many years AND upgrade their old mattress tremendously!

Mattress topper was soft but unfortunately too warm. Both my wife and I found we were sweating from this after adding it and slept better after removing it from my bed. The topper was also about 2 inches smaller for both length and width that our mattress

I just bought this topper home YESTERDAY. I have a very bad back, degenerative disc disease, many ruptured discs, in neck, and lower back. I have severe psoriatic arthritis . My bed is very old, and figured let me try this. If it doesn't help, than it will be time for purchasing a new bed. I was anticipating a few nights of waking more achy than usual. It normally takes anyone a few nights to adjust to a new mattress. I am beyond thrilled to say I woke up, feeling much better than I have in a very long time!! Thank you serta!! I read hundreds of reviews, and this topper had the best ones. Granted, it's one night, but this one night, IS VERY welcomed and UNEXPECTED WHAT A Great night's Sleep!! I will update this review in couple weeks, see if things continue on this path.

I bought this two days ago. My wife had to have it, and wanted to put this on our 12 year old mattress. This was a innerspring pillow top in king size. It was 14” deep. I thought it would be better to get a new mattress. I wound up buying a Serra sleep to go from Sams. We both like the mattress, I will do a review on the mattress there. My wife felt like she was missing the pillow top feel, and a friend recommended a topper like this one. I did the research before buying the mattress, and we had decided on this one, so this decision had already been made. After using the new mattress, my wife still wanted this topper. I went and got this, on sale $30 off. I got it Home and was surprised it was 2 pieces, I must have missed it somewhere. Not a problem, just an fyi. The memory foam is just a bare slab of and off white memory foam at 3” thick and about the size of your bed. It’s about an inch larger all the way around the bed, sides and length. At least this was my experience and I had seen that in a couple reviews. The actual pad part is like a fitted sheet. This one felt awesome on the top, it will cover about 21” it looks like. So this should go over a 16 or 17” mattress. The pad has a small amount of foam and fiber fill. The truth in in the feeling for you. To lay on it, I definitely sunk down into this thing. More so when the pad isn’t used. Not a really bad thing, it actually felt good, this is wrapping you up like a marshmallow. It seemed to give support, while being really soft at the same time. I would think a back sleeper, side sleeper, stomach, or combo, like myself could do well with this. I am thinking this would probably work better for us on a firm, non pillow top innerspring mattress. Your mileage may vary. The bottom line, I returned it today. That’s the good news, I felt like this thing was very well made, and with a 10 year warranty, the quality is there. It just wasn’t for us. I could go either way, but happy wife, happy life. i did feel like it was too much on top of the memory foam mattress we just bought. The cons for us, it slept hotter than the mattress, it felt like my old mattress, which slept hot. It was just too much of a sinking feeling. Also the sheets are an issue. I had bout 2 $100 sheet sets recently, got the deep pocket ones, and they still were too small. The extra 4 inches was too much. The best thing is that sams gave a refund with no questions about it. We got to buy it, planning to keep it and have the ultimate bed and wound up returning it the next day. If your thinking your pains need a new bed, I would try this. The quality is very good.

I recently bought a new mattress and wanted a nice topper to go with it. I bought a cheap one on AMZ that was ok. Then a friend recommended I get this one. It was a Serta and had mostly good reviews, so I bought it. Initially, I loved it, but no more. The topper constantly has to be readjusted because it won’t stay in place. It’s such a horrible design flaw that I don’t see myself ever buying another Serta product.

I LOVE this mattress pad. It is so comfortable and I sleep so well and don't wake up sore every morning. I have it on the least expensive sleep number bed and the combo of the two is wonderful. I bought another for our guest bedroom because I like it so much. However the first mattress had a terrible odor that still hasn't completely gone away more than a month later. The 2nd mattress I ordered had no odor at all. I actually ordered a replacement for the first one because it smelled so bad and just received it yesterday. It has very little odor and I'm sure will dissipate quickly. My advice is to buy this pad! But, if you get one with an odor, order another.

Bought for a very firm memory foam bed that we have on our RV. Unwrapped and placed on the bed, put the cover on and tested it out. I fell asleep right away and did not want to get up. Love the zip cover. Serta 4 inch with pillow top. Really want one for the bed at home now.
