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!

Great value, great topper

We have a worn-out foam mattress which needs replacing. My lower back gets very stiff after sleeping on it. We don't want to spend the money on a new mattress at this time. I purchased the mattress topper, hoping it would relieve some of my back stiffness. It's done exactly what i hoped it would. It's not like a new mattress, but the next best thing. Very Good. Thank you.
