Massive difference

So we were staying out of town at Great Wolf Lodge, and the bedding unfortunately was awful and there was no way I was going to be able to sleep in that bed for four more nights so I ordered this and it made a huge night and day difference, so thankful I did. It definitely reduced my pain and almost took it all away, it seems like a very durable topper as well, very heavy and sturdy as well as the cooling effect I love.

The memory foam mattress topper that I received looks different from the one pictured. It is heavier than expected and appears to be 5" thick instead of 4. It has a wave pattern on top, instead of the egg crate look. I bought the king size so I could cut it to fully cover my queen size mattress. It is very comfortable with the wave side up. Not sure why they have it pictured with the wave side down.

I bought this bc This has no gel in it. The gel in these toppers makes them way too mushy for bad backs. This one is Incredible. It's not mush foam. It's supportive foam. I'm very athletic(I hike 5 miles daily!)%26 it has helped my sleep immensely!' I'm also almost 60.
