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.

This mattress topper is exactly what I wanted. I bought a mattress just a few years ago that turned out a lot firmer than I expected it to be. I had another topper that helped, but this one really does the job.

Worst thing about this topper is my husband and I don’t want to get out of bed. Very comfortable. Best sleep we have had in years. Definitely recommend.

We bought two of these to enhance the mattresses our kids use. There is a significant difference in added comfort, these gave new life to the old beds.

I bought this a few weeks ago and I love it. It is soft, cushions, but still supportive. In fact I have bought two more for more daughters. Great find.

I had no problem setting up myself and I am 63. Very comfortable the moment I layed down on it. Helped significantle with my sciatica nerve pain. I highly recommend this product.

Great buy. Super comfortable. I aired out the mattress for a couple days and it was fine. My husband and I are having awesome sleep. We keep having a hard time wanting to get out of bed lately.

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.

This mattress topper made all the difference in our older mattress without having to spend a fortune replacing the mattress. It's so comfortable that we bought a second for our daughter.

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 :)
