I was happy with my mattress but my partner complained the mattress was too firm, so I purchased this, thinking if it was too soft for my comfort it was not a bid investment. Well, let me tell you. The first night I slept on this, I did not move once. I was so comfortable! And when I woke up, my posture was perfect and my back felt better than it had in years. Every night since, I sleep so comfortably. It's just the right amount of support.

Amazing!

I bought this as I was staying as a guest at my mom's as a transition between moves and my furniture was moving across the country and the mattress I was on was awful! I bought this and was able to get comfortable and actually sleep! I've been on a sleep number adjustable bed for years but found this quite comfortable and slept very well considering. Highly recommend!

Very comfortable!

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!!
