Don't just take our word for it

It's very comfortable!

My husband and I sleep much better than our 12 year old memory foam mattress. This is our first Casper and definitely won’t be our last!

Jackie D. (Arbela, MO)

The One

Love it

This mattress is so comfortable and you don't have to wait to use it after it arrives. This mattress is firm, but you also sink into it a little. Just how I like it.

Stephanie P. (Fraser, CO)

The One

The second one.

This is the second one we have purchased so that should tell you that we like it Casper! Very comfortable and the first one has held up very well so much that we bought another for a different bed.

Gary G. (Bellingham, WA)

The One

We love our new Casper mattress.

It has the perfect firmness, yet like sleeping on a cloud. I don’t feel my husband moving during the night. Sleeping soundly and our daily back pain from our previous mattress gone in one night!

Julie R. (Cedar Grove, WI)

Cloud One

Love it!

What a difference from our old pillow top spring mattress. Comfortable from day 1!

Sham M. (Vicksburg, MI)

Cloud One

My wife and I both love our new mattress.

We are both well into our 80's and we immediately noticed that we sleep better and wake up with less joint pain.

Cloud One

Frequently Asked Questions

Who are foam mattresses best suited for?

Foam mattresses are a great fit if you want pressure-relieving comfort with steady, all-over support, especially if you like a cushioned feel that allows you to settle in and stay asleep. Casper’s foam mattresses are built with layers of responsive, supportive, and breathable foam designed to relieve daily pressure.

Are foam mattresses the same as memory foam mattresses?

Not exactly. “Foam” is the umbrella category (different foam types can be layered together). Many foam mattresses—including Casper’s—include memory foam as one of the layers for contouring and pressure relief.

Are foam mattresses good for hot sleepers?

They can be. Our foams are designed to be breathable—The Cloud One features open-cell, breathable foams to help prevent overheating, and Casper uses breathable covers to promote airflow. If you’re looking for a cooling mattress, explore the Snow and Snow Max

Do these foam mattresses come in a box?

Yes. Casper foam mattresses ship as a foam mattress in a box—compressed in an air-sealed bag, rolled, and boxed for easier delivery and setup. They expand after unboxing and breaking of the plastic seal. Feel free to discard the packaging afterward as the mattress cannot be recompressed.
