I have two of these on two different beds. I had an old mattress topper and had to replace it (our golden puppy thought it would be a good idea to bite chunks out of it). This one is by far more comfortable than the old one. The cover that comes with it is also a better quality. This is great for new or older mattresses.

For the price and quality, this thing is top notch! If you have a bed that has lost its life and you are looking to extend the comfort, this is it!! The reason I gave it 4 stars instead of 5 is it is much softer than expected. It takes some getting used to because it is so soft but it’s much better than the concrete bed underneath. Just a heads up because the description doesn’t really state how plush this is, you don’t think 4 inches would make that much of a difference and it does. So in the case you are looking to make a hard bed soft, this is an amazing choice - if you have a soft bed that you are trying to add comfort to, maybe choose a 3 inch instead.

Hi, received my Serta 4' pillow-top and Memory Foam Mattress Topper. My purchase came on time, it was easy to open and place on my bed to air out. The smell was overpowering, had to air out a few days, never knew my nose was so sensitive, my family members really didn't notice the smell. After a week I was able to sleep on my topper and it was fantastic!! I have had the best sleep ever, my back used to hurt and my sciatica bothered me. I'm not saying that I am not in pain any longer, just that I can now tolerate it enough to sleep through the night. It is very comfortable and feel very spoiled now. I gave my rating as a 4, would have been a five except for the smell. Very happy in Lafayette IN

Excellent product and a fantastic value. We have bought 3 of these in various sizes and they have all performed well and provided great support and comfort. We just bought this for my daughter’s dorm room and it made the hard dorm mattress so much better. It was the first thing she requested before even heading off to school.

We bought this online and picked it up in the club the next day. My daughter put it on her bed immediately and slept on it that night (she didn't care that it wouldn't be fully expanded for a couple of days). She said it made her bed much more comfortable (she's not ready to replace the old mattress yet) and that she has slept well on it every night. It came with a nice pillow-top mattress cover.

This mattress topper was the perfect solution for us. We had a different one that was due up for replacement that was 2" of memory foam glued to 2" of regular foam. The 2 layers had separated and would wrinkle under us and slide around on top of the mattress. This new Serta one, being 4" of just memory foam, does not wrinkle, and is not slipping on top of the mattress. My husband is sleeping so much better. Some have asked if it was really soft and would you sink down in, but I do not find that to be the case. I can turn over easily and don't wake with sore hips or shoulders like I do on just a regular mattress. Well worth the investment and brings new life to your mattress.

Very comfortable topper. I really like the combination of both memory foam and pillow top. Pillow tops tend to compress and stiffen after time and it's hard to move in memory foam once you sink in. Having 3 inches of foam topped with 1 inch pillow top has proven to be the perfect combination thus far. Prevents becoming stuck in the foam but remains soft. It has condensed slightly after 1month so I think to maintain longevity it will have to be rotated along with the mattress. It is heavy so 2 adults should tackle the task. Our 8yr is begging for a set for her bed and even asked for it as a Christmas present! Needless to say we like it so much we have purchased that 2nd set and it has a big bow on it right now! I would definitely make this purchase again if I had it to do all over.

My husband and I bought one to put on our SleepNumber bed instead of paying for their pillowtop option. This was such a good choice. We have had this topper for 2 years and it is just as soft as when we got it. We recently purchased a second one for our daughter’s bed. She is sleeping better and loving hers too.

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.

I had a rather hard mattress so I’ve decided to get a topper that can mold my body while I sleep sideways or make the gap on the back of my waist more supported if I lay flat. But this mattress, although not too thick still was too soft. I have soreness in the morning. I think there should be a way of support and softness coming to a balance. Unfortunately it’s still kinda on the softer side. But my kids really like it when they were rolling around on my bed. Maybe it’s me that need to get used to it.
