Allswell 4” Memory Foam Mattress Topper Infused with Cooling Diamond Gel, Full

I used this on a sleeper sofa I had to sleep on for a few months. It made the bed much more comfortable. Better than the bar I could feel through the thin mattress that was hurting my back each night. I just put this on top of the sleeper sofa mattress and then used a fitted sheet to bring the 2 together. I plan on using it on my full size bed when I return home next month. You'll want to rotate it about every 2 weeks to keep it firm and let air get back into it. I'm glad I went with the 4 inch version and not the 3 inch model. Much cheaper than a Dormeo.

We are currently in the process of remodeling and sleeping on a sofa bed. Our backs have been hurting and a dip in the middle formed rather quickly. We ordered this from Walmart since our local store was out of stock. It came the next day right on time without any issues. After letting it fill out for most of the day (the instructions state 24-48 hours) we slept on it that night and it felt amazing!! It's soft but firm enough to support our backs and we didn't wake up sore and stiff like we have been. It is a great buy and we plan on using it on our actual bed once we are done with the remodeling. The cooling feature seems to work well, I sleep hot and do feel a little warmer if I wake up in the middle of the night but nothing that keeps me from falling back to sleep. We didn't notice any strong chemical smells when we first opened it so it's great if you need to use it shortly after getting it since you won't have to wait for the smell to dissipate. This made our sofa bed feel like a brand new top line bed. We love it!!
