Customer Reviews
I bought this, along with the alternative down cover for a Father's Day gift. My dad said he used to wake up a few times a night before he had this memory foam mattress topper. Now he sleeps through the night without waking up. He says it's like sleeping in the clouds. I also ordered the 3" memory foam for myself and love it.

Not even a year ago my husband and myself had bought a new mattress set. I let him pick it out. That was a mistake! My back has been killing me since we had got this bed. So finally we decided to get a memory foam mattress topper. We looked around in stores, and their pretty expensive, even for just the 2 inch one (i paid the same price that a 2 inch one costs in the store/other online places for a 4 inch one!). Needless to say, even the first night I slept on the mattress topper my back felt relief. As we've come to break it in etc, it's gotten even better. As for the pillows, I had a memory foam pillow before we bought the mattress topper, and it has helped relieve my stiff neck/neck pain by tons. I'd love to meet who ever came up with these items. I wake up easier, i feel more rested... it's amazing.

I love my mattress topper! I started off with a 3 inch topper that I bought from Overstock a couple of years back...I loved it and bragged about it so much that two of my sisters have purchased mattress toppers too! I recently bought this 4 inch topper because I wanted to give the 3 inch mattress topper to my niece as her mattress has seen better days and can't afford a new one at this time. Now she sleeps great and thanks me often. I would recommend this product to anyone who wants to get a better night sleep and not wake up with aches and pains.
Very comfortable, only downside is that it is about 3 to 4 inches narrower than the full size bed. Should have ordered a queen size & then cut it to fit the full size mattress. Other than that we love the 4" Memory Foam Toppers. We have purchased several for children & other family members.
I was about to start shopping for another mattress because although the one I have is only 2 years old, it was not as comfortable as I hoped. I would wake up aching. I purchased the topper and omg I love it. I was skeptical because I was sure I was going to sink in and have that tilt effect but it doesn't!I have ALWAYS needed to sleep with a pillow and have purchased literally dozens of pillows to find the right one but with this topper I don't even need one! It's a great value, it arrived fast and its durable. Going to get another one for my niece.
