The longer you lay in one spot the harder it is to roll over. Its to HOT too. There is a chemical smell from the foam so it needs to air out about a week before you sleep on it.

This topper has been great but calling it 4 inches would be a bit deceiving it's really 3 inches and a thicker mattress pad that goes on top of it. Overall ir's nice and has been great.

I brought this mattress topper for my oldest daughter, she absolutely loved it. Her sister tried it and had to have one. So I brought a second one for her. She said she now sleeps great and doesn’t need to use a pillow. I may buy one for me.

We bought this to replace a similar one (same brand, actually) that was several years old and a bit worn. Works as expected.Good product at a great price.

I bought a firm mattress and it was very uncomfortable so i was looking for something to help. This mattress topper was the answer! It’s soooo comfortable. It’s like I’m sleeping on a cloud! I can’t wait to go to bed every night :)

This is a comfortable / affordable alternative to a new mattress. It does take some getting used to. You sink down into it like a fluffy pillow. I would purchase again.

What the Serta 4" Pillow-Top Memory Foam Mattress Topper covered was a firm mattress that was getting lumpy. The Serta 4" Topper is wonderful. It is so comfortable and our sleeping time has improved.

Only issue is it inches off the bed. Every morning I have to move it back on the bed. This happens on all three beds with different sleepers. It moves 2-4 inches.

Awesome!! Finally found the perfect mattress topper. Actually put it on my tempurpedic bed. I needed a little something more and this was it. My husband and I sleep all night and no aches and pains when we wake up! Love it!

When I bought it my feeling was it's 4 inches thick. There is 3 inches of foam and a thin mattress cover that doesn't equal 4 inches of foam. I am 6 feet 5in.. tall and 245 lbs. This doesn't work well for me.
