Size Guide

Which mattress size is right for you?

When picking your next mattress, it’s more than just personal preference—two key things to keep in mind are how much room you have and who’s sleeping in the bed.

King Dimensions 76"x80", California King Dimensions 72"x84"

Upgrading to a King mattress is a game-changer if you’re sharing space with kids or pets. And if you’re tall, the extra length of a California King could be just right.

Full Dimensions 53"x75", Queen Dimensions 60"x80"

A Full size mattress is ideal for young adults or those with a smaller bedroom, while a Queen is the top pick for couples or anyone who enjoys extra space to sprawl out.

Twin Dimensions 38"x75", Twin XL Dimensions 38"x80"

The Twin is the smallest option, ideal for single sleepers. While the Twin XL is a dorm favorite it can also create a Split King if you purchase two.

Which pillow size is right for you?

Pillow sizes can vary, but standard pillows, also known as queen pillows, are typically suitable for all types of sleepers. If you prefer extra space or need to fill the width of a larger mattress, king-size pillows, which are about 30% larger, are a great choice.

Frequently asked questions

What makes the Cloud One the right choice for me?

An all-foam construction for anyone who loves a medium soft feel.
Continuous support for all sleep positions.
All-new patent-pending Casper Core+™ for sleepers looking for the latest in mattress innovation.

Does the Cloud One memory foam mattress sleep hot?

All of our mattresses are specifically designed to sleep cool. We run thermal imaging tests and sweat tests to make sure our mattresses feel nice and breezy throughout the night to keep you comfortable.

The Cloud One features Casper Core+™ which offers a boost of plushness while giving you all the support and breathability of The One.

If you are a hot sleeper, Snow Technology is our most advanced solution to nighttime overheating. The combination of HeatDelete™ Bands, Phase Change Material, and cooling Snow Cover keep you comfortably cool from the moment you crawl into bed.

How do I clean my Casper Mattress? Can I remove the cover?

Do not remove the mattress cover to clean it or the mattress or for any other reason. If you need to clean your Casper mattress or cover, we suggest spot-cleaning affected areas with water and mild detergent. Be careful not to saturate the mattress with too much water and/or detergent, as the foam in the mattress core will soak up water and detergent. Allow the treated area to air dry completely before putting your sheets and bedding back on.

For an easier method of keeping your mattress clean, we recommend the use of a stain and water-resistant mattress protector, which may be removed and cleaned as needed.

What kinds of bed frames are compatible with Casper mattresses?

Casper mattresses are designed to work on a firm, solid surface like our foundation, platform, or adjustable bed frame. Having the correct support ensures the performance and longevity of memory foam/hybrid mattresses.

For slatted frames, we recommend using bed slats that are flat (not bowed), wooden, and no more than 4 inches apart.

How long will my Casper mattress last?

Every Casper mattress is engineered for both comfort and durability, our premium foams (and innerspring coils inside our Hybrid mattresses) provide lasting support for a full decade—our warranty backs it up.

Can you expedite shipping?

All Casper products ship via UPS Standard Shipping which typically takes 2-8 business days. Since we cannot expedite orders, your best bet would be to visit one of our stores. Click here to use our Store Locator to find the Casper Sleep Shop or partner store nearest you!

What is a mattress in a box? How long does it take for a Casper mattress to expand?

A mattress in a box is a mattress that’s compressed in an air-sealed bag and rolled tight so that it can fit into a box that’s easier to maneuver than a traditional mattress. This innovation gives you the freedom to explore our mattress collection, compare choices, and order the best mattress for your needs online, all delivered straight to your door.

When you receive the mattress, all you’ll need to do is pull it out of its packaging, lay it flat on your bed frame or floor, and let it expand.

Foam and hybrid mattresses can be slept on almost right away but may take up to 48 hours to expand fully. Our Snow mattresses are primarily made with memory foam and can take up to 72 hours to expand fully.

Can I get another copy of the setup guide?

Absolutely! Click here to download a PDF of the mattress setup guide. We recommend giving your new mattress a minimum of 24 hours to expand.
