I bought the 3" High Density one (full size} because they said it was good for both side and back sleepers. It was said high density made it more firm. I only weigh 89 pounds but I sank down low in it. I almost couldn't get back out of bed. I need to return it! To be called high density it should be 4-5 lbs psft, and this is 3.

I haven’t notice a difference yet.

I ordered the 4" memory foam topper, after a thorough chat with an agent online to help me assess my needs. It arrived quickly, was easy to install and was great quality. Unfortunately it wasn't quite the right thing for what I needed, so I did process a return/refund request, but even that process was well-supported. Therefore, i would like to leave a very positive review! A great, well-run company. The mattress pad was superb, you could even sleep on the floor with it, it was that cushy!

Bought the firm topper because of a long time injury and it came in this is extremely soft. Need to return but no way to get it back in the box now

It seems to hold me, then I feel like I am sinking. Then I am a side sleeper and back. Then my shoulders are sore getting up. I am still trying to figure this out if it is giving the support I need.

The 2inches of memory foam on top of my rather firm mattress (also memory foam) made just the right difference for side-sleeping.

I bought the 4 inch high density topper. . I've only had it a couple days and I can feel the difference in my sleep quality.

Not as firm as I expected for "high density" foam. I will return it.

It’s not as soft as I thought it would be and not very comfortable.

I struggle with chronic pain, especially my lower back and hip area. I’ve never been able to find the right mattress. And if I did find one, it wouldn’t stay that way. I decided to give the high density mattress topper to see if this could help me at least sleep better and not toss and turn trying to find a comfortable position in bed. Absolutely recommend this!!! It’s like a whole new bed. It’s comfortable no matter if I’m on my back or my side. It really meld with your body position, if I roll over there’s not a dip that normally I would struggle to not roll into. This mattress topper reshapes. Love it!!!

Never slept so good in years. thank you.

I was having a lot of trouble sleeping until I got my mattress topper. I sleep like a baby now!

Seems a bit too soft. I’ve only had it for two days do maybe i will adjust to it. Been waking up needing to shift several times during the night.

I have back problems, and have struggled to find the right topper. I'm so impressed with the 3 inch high density. Do yourself, and your back, a favor, and get this product

LOVE IT!!

I bought a sleep number P6 smart bed bed a few years ago, and have been in severe pain. For the last year had been so bad that I was taking ibuprofen every night to go to sleep. I finally ordered this mattress topper and within 24 hours, the pain has significantly improved, and I don’t feel the mechanics of the bed under my body anymore. It is heaven. Definitely worth the purchase.

Attempting to return and unable to locate a donation/charity that will accept the topper.

I slept great on the mattress, it was very comfortable

Very comfortable, especially for myself as a side sleeper with hip pain (trochanteric bursitis). The topper does shift a bit requiring daily adjusting which is kind of a pain but this is comfort that I haven't felt in a long time.

As a side sleeper and hip arthritis sufferer, this 4" topper has provided the relief I needed to get a good night's sleep. It's a bit sweaty in the hotter weather, but worth it to be able to sleep without pain. HIghly recommended.
