    I just love my Casper MattressI really do love the mattress, I have back problems for over 8 years and a mattress is very important to me. I highly recommend Casper mattresses. Also the return policy is excellent, it gives you the time to really test out your new mattress.

    Lumpy in less than one yearWe purchased the Wave Hybrid Casper mattress less than one year ago and “wave” it is — our mattress looks like a couple of waves in the ocean by how much it dips on each side where we sleep and rises in the middle. I absolutely do not recommend this mattress. It was comfortable at first, but not anymore. We are not overweight or uniquely shaped people. We had our previous mattress for 7 years and only during the last year did it start to “sag”. I regret purchasing this mattress and wish we would have gone to a store and bought something that was not shipped in a box.Don’t do it.

    Not worth $3,000Recently bought two other queen mattresses from Amazon. Both under $500. They came rolled with instructions just like the Casper Sleepwave. Comfort level great, but I still have some back pain. Decided to splurge $3,000+ for our own mattress. Got the Casper Sleepwave!.Ya know? Not much difference. With a blindfold test, I couldn’t tell the diff.

    Defective from the factoryMattress is okay, but nothing special compared to other brands with similar construction. Lowest rating is not based on mattress comfort, but on Casper quality control and service. Once the vacuum sealed package was opened, it clearly had basket ball size liquid stains in the middle of both vertical sides. They became more pronounced upon full expansion (see pics). I have no idea what caused the stain, only that the shipping box and plastic packaging was not damaged. The stain was inside the sealed plastic. This happened at the factory somehow. I called Casper and they told me they could not address it until after the full 100 day trial period. They should have immediately and directly removed the old one and replaced it with a new mattress. Failed Casper company customer service. I called Amazon and they have sent me a replacement, and told me the old one would be picked up, but have not as of this posting. It’s still leaning upright on a wall in the front room office of my house. If you order one of these mattresses, make sure you open the box and check the product before accepting the delivery, so that if there’s a problem you can reject the delivery on the spot. Hope this helps.

    Comfortable, bed and easy to get used to.Very comfortable, easy to unpack, pricey but worth it. We did so much research and this is the best option for us. Very happy with our mattress!

    Still Struggling with SmellIt’s been two months now and while this is a very comfortable mattress to sleep on, I’m still getting whiffs of the chemically smell of the foam. I was hopeful it would go away in just a few weeks but it hasn’t. I’m considering returning it but really don’t want to go through the hassle.

    Don’t buy don’t try. Poor productBuyer beware. It is impossible to return this product so don’t purchase it. They want it folded and there is no way to fold it once air gets into it. Anyway this was a huge disappointment. I ordered a cal king and I don’t know what size came in but it wasn’t a cal king. It was too short. When u sit on the edge of the bed, ya slide off. there is no support for the first 12 inches of all the sides. This major amazon fail has put such a bad taste in my mouth that I am banning my family from using amazon.
