I've had this on my bed for 2 weeks. ODOR: I am very sensitive to smells. I removed the 2 pieces from the box but did not unwrap them for about 10 days. The opened box did smell. I noticed no smell when carrying the two pieces into our guestroom nor did I notice a smell when I unwrapped them & spread them out. Still no smell now, in my room under use. SIZE: The Queen size is exactly the size of my queen mattress.The pillowtop mattress cover easily fits around the memory foam topper & my mattress. I think it would fit around my box spring as well. STABILITY & COMFORT: I move a lot. The memory foam does move left & right a bit but after 2 weeks it does not yet require repositioning. I was worried that it might be too warm or cool - it is not. I use a top sheet, a lightweight fluffy blanket, and a quilted top blanket. I do not add or remove covers as I did previously: whatever I require when I go to bed is adequate all night. SUPPORT: Seems more than adequate. I have an artificial hip & a CPAP. The only change I have had to make is a slimmer pillow under my head.

I compared prices, plus thickness and qualities, of several different brands and companies. I’m so glad that I settled on this particular cushion topper. Having recent knee replacement surgery, I’ve had to sleep on a downstairs couch which was somewhat uncomfortable. Putting this topper on top of the couch was a game changer for me. It’s so soft and luxurious, but also keeps its form. I’m able to sleep well because the couch itself feels more evened out and supported, but again super soft. You won’t regret this purchase.

Decent Pillow-Topper. Nothing spectacular. Deep fitted sheets will not go over the mattress and topper. Topper constantly slides down with use. Original mattress too firm, so topper did help a bit. But has too become uncomfortable after 1 months use.

I bought two of these for my twin boys. We were pleasantly surprised at the plushness and added comfort they provided. Just note, regular sheets will not fit over it AND the mattress; additionally, without anything stabilizing it like straps, it can "travel" across the mattress in the night. Overall, my boys are resting much better, and the pads are extending the lives of their current mattresses.

"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.

I bought this about a month ago and am very glad I did. The mattress we have is just too firm. It was causing back and hip pain. I got the Serfs 4" pillow top and memory foam mattress topper and could not be happier. It is both soft and supportive. No more back or hip psin. It's like sleeping on a cloud.

Bought this a couple weeks ago and love it! Easy to add to our California King size mattress. So comfy and soft it's hard to leave in the morning . Was worried it would smell weird ( memory foam sometimes does) and be too hot- it isn't smelly or hot! I want to cover every bed in the house with these! Great price too!!

If you want to fell like sleeping on a cloud this is for you..When you first lay on it you fell a little sinking felling then you are floating..You drift off to sleep so fast..it is morning before you know it..You wake up and get out of bed.. with no pain at all..this thing is a great..Enjoy...

Very comfortable, but smells strongly when opened. Its been about a month, and I can still smell it, but its not overpowering like when it was new. When I first got it home and opened it, the pillowtop was the wrong size. It was a full (said it on the label with the dimensions, and the label on the pillowtop bag said queen) the topper was the correct queen size. I promptly retuned to sams to exchange only to find out they can't take it back. They did give me a refund on gift card and I bought another one, but I had to dispose of the bad one. It has helped me sleep better, even shows on my fitbit sleep score.

I was a little skeptical but that skepticism make away within 2 seconds of me resting on this mattress topper. I should have bought these a long time ago. In fact, I'm ordering them for the rest of my needs too. Turns any slightly hard or unforgiving mattress into a soft haven of restful blissful grace.
