Very thick and super comfy!! Love sleeping on it. Only negative for me is the mattress pad that goes over the foam is made in China (foam in USA and assembled in USA) and I couldn't see that online, only when I unpacked it. I try never to buy anything made in China-safety issues!!!

"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 purchased this hoping to alleviate the pain in my hips and knees every morning. It is a very nice topper set but it was much too soft for me. It did conform to my body, but let me sink to the mattress I was trying to avoid. If you need plush this is the topper for you. It is a very nice set. I loved the cover that came with it. But it went back with the foam when i returned it to Sam's.

This is not fiberfil . It doesn't have a gel memory foam pillow top either. It is exactly what it states on the box pictured. It's a 3 inch memory foam base with a quited protector that with a stretch of imagination can be considered 1 inch. Together they make a topper that's about 3.25 inches.

Packaging was pretty terrible. The shipping box was half open and the items didn't even arrive in a serta box inside the shipping box. The topper wasn't even in a waterproof bag. Just exposed to the elements in a brown shipping box. Shipping complaints side, it is very comfortable. Now I just gotta find a fitted sheet to go over the mattress+ topper. Also: the plush cover in the box only goes on the topper. It does not go on the mattress and topper together. I figured that out after about an hour of struggling.

Bought for my son, so glad I did... he’s a bit heavy and his mattress was starting to sink in...this brought his bed back to life and he loves the fact that he’s sleeping more comfortably and the whole night.... great product. Will get a king for myself...

I have bought a dozen toppers over the years with college kids moves etc. I saw this in club and thought Serta perfect. The worse ever. It doesn't even get close to the normal size. Large areas when it never expanded. Now I have to lug this back to store to return. This really is the worst product ever purchased. So disappointed.

Slid off bed constantly

Hubby and I have a split king adjustable bed with latex foam mattresses. The mattresses are too firm so we purchased two Twin XL toppers. Opened up them up, put them in the pillow top cover and they molded to the beds right away. Oh my, they are so comfortable! They made our mattresses feel wonderful. However, after a couple nights of sleep the pads start shifting in the pillow top covers and off the mattress. The separation of two Twin XL mattresses now feels like a 6" valley in the middle as the pads both shift outward. We wanted to keep the individuality of the adjustable beds, but maybe we should have purchased a king sized topper. We've tried everything we can think of to keep the toppers in place; nothing is working. So if you have a split king like we do, I wouldn't recommend them for this type of bed.

Paid $149 at Sam's Club. I bought this a couple of months ago and it is extremely uncomfortable and it constantly slides off our bed no matter what we do. We end up having to pull it back onto bed few times a night. I have not slept well since I put it on our bed. We gave it time thinking it would relax or something but is worse over time not better. I don't know if Sam's club will allow me to return it, if not it will unfortunately be landfill!
