I ordered this to see if it would help with my body aches and pains and it does. It took a couple nights to get used to because it’s so cushione. My mattress is firm and this makes me feel like I’m sleeping on a cloud. I don’t turn back and forth all night like I used to because of hip and back discomfort. The foam is USA made and earth friendly materials. I would recommend it. It came in two days and I thought at first I had the wrong one because it was in a plain cardboard box. On the packaging however it said Serta. Also take your time spreading it out. It takes about a 1/2 hour to fully straighten out. Love it

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.)

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.

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.

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.

Bought it 2 weeks ago! Was waking up with stiff joints and back ache. Decided to buy a new mattress. Went on line, saw this for way less money and figured i would try it first. It arrived, opened it and put it on our mattress. It did have a chemically smell as stated in other reviews. Wasn't really surprised by it though, it's a giant chunk of foam! First night till now, sleeping like a baby! No joint pain! No back aches! Truly happy! Smell has dissipated over time, but it was never really terrible! Love it! Recommend it! Would buy it again!

Comfy. Purchased for spare room. Wanted our guests aka: family to be comfortable. We tried it out and it really is comfy. Less expensive than getting a high end mattress for just an occasional guest. Maybe once or twice a year. So it saved us money and provides extra comfort. We looked around quite a bit before deciding. I wonder if they would consider making a short Queen for our RV?? Just a thought’

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.

Yes, The memory foam did smell, but frankly not so much that it couldn't have gone on the bed straight out of the box. Left it unrolled to air out 2 nights--no odor issue at all. Easy to put on the bed, plenty of fabric to go under the mattress, and more importantly, very comfortable

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
