I have slept on a Casper mattress before, and liked it, but it was obviously a different type. This one actually sinks in dramatically when you lay on it. I had a hard time staying on my side of the bed while sleeping because my husbands side had a much deeper indention/crevice and so it caused me to roll/slide towards him! If you like a soft mattress, then this one is for you. It is Definitely not even slightly firm!

Took awhile to receive but great purchase. very happy with my new mattress. We have another foam hybrid bed that is 3 times the price which I thoroughly love, but this is great for guests or an average sized adult to sleep on nightly. For the price I couldn't be happier. Very comfortable.

Took a few days to get used to the mattress. I'm now able to sleep through your the night and actually get more REM sleep.

I've purchased Casper before and been quite pleased and was not disappointed this time. The Sam's Club price was terrific!

Amazing bed. Great for the pricing offered. Competitors are higher priced. Easy to open box and I do recommend not sleeping on it until it's fully expanded. Although you can sleep on it.

I bought this because the reviews said how soft it was. Since I am a side sleeper I thought it would ease the shoulder pain from injuries that I have to live with. The mattress puffed up to its full 11 inch height within minutes of removing it from the box and wrappings. This mattress is much too firm even feeling hard throughout the night and has caused The shoulder pain to get worse. I have use this mattress for two weeks. I do not look forward to lying on this mattress each night and I do not know how I can get it back to the store after it has expanded and box and wrappings have been thrown away. Do not buy If you are a side sleeper or desire a sink into me mattress.

Even better than I thought

Great mattress for the average size people, I have 4 of these and I am not disappointed with any of them. The oldest one is 8yrs.

Arrived earlier than expected. Mattress is very nice and popped up very quickly. It is for a guest room and was just perfect! This is a nice size mattress too.

Very comfortable mattress for a great price. This is the third foam mattress we have bought and I was surprised that this did not need any prep time, it fully expanded right out of the packaging! Regardless we let the mattress air out for about 72 hours to get rid of the initial packaging and chemical smell but it dissipated fully. The mattress does not feel the same as the regular Casper mattress you will likely test out in a physical store but its still extremely comfortable. It is firm yet plus on top. There is not much side support so keep that in mind and ensure you get the right size. Worth the price and seems like good quality that will last a long time.
