Very comfortable and worth the price. I ordered the single size. just wish I could have ordered it in a "super single" size. I use it on a converted water bed of that size and although it doesn't cover the entire bed it is the only size that is workable for a super single size . There are some super single size toppers out there but they appear to be inferior quality.

We purchased this mattress topper to go over our queen-sized memory foam hybrid mattress. Our mattress itself is rated medium-firm, which is good for me as I have a medical condition with my back, but not so great for my partner. Without this mattress topper, our mattress was too stiff/firm for my partner's comfort, relegating them to sleeping on the couch each night. We took a chance on buying this mattress topper, believing either the topper was going to make the mattress usable for my partner or we would have to invest in a different mattress altogether. I am writing this review about 2 months after purchasing this product and thankfully this serta mattress topper has been worth every penny we paid for it, allowing my partner to get a good night's rest. I would not hesitate to purchase it again. I would also recommend it to anyone who needs to add some softness to their mattress without losing the supportive feel.

Very comfortable. We bought two so far. One stays in place with no problem but the other slides on the mattress. I think it's better for a thicker mattress. Very comfortable. Even though the order instructions are numbered, read all the way through before you begin to avoid unpleasant expletives.

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!

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.

For the last 4 1/2 years I haven’t been able to sleep on my right side following shoulder replacement surgery. My bed was just too hard. When I recently started waking up with hip pain, I knew I had to do something. After reading reviews on multiple mattress toppers, I decided to give this Serta a try. What a difference! I’m sleeping on my right side & waking up without hip pain.

Such a great purchase! We bought a new bed about 6 months ago. My husband referred to it as "the slab". It was a plush mattress and not a pillow top and was too firm. I finally decided to get this topper and so glad I did. The bed is fantastic now! We couldn't be happier with the comfort. You won't be disappointed if you purchase this.

"Serta 4" Pillow-Top and Memory Foam Mattress Topper" -- The mattress only came with a pillow top w an attached mattress cover with no foam. i waited a few days for the pillow top/foam to expand, but did not expand. returned the item.. so disappointed, plus the box was in terrible shape and took a long time to arrive.

The topper slides a lot with no way to hold it in place. I find my self rearranging it very often. The first night I used it I woke up with back pain but after a few nights my body got used to the topper. It is very cool but it would be nice if it had straps to hold it in place. Not horrible for the price though but I don’t think I would buy again.

We bought two of these to give to our twin (fraternal) grandchildren for their 12th birthday a little early. They were shipped directly to them (some 215 miles from us), and they have thoroughly enjoyed them since. They are very pleased with how soft they are on their twin size beds.
