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.

Dream-Worthy Reviews

Real feedback from customers who have experienced the Casper difference.

It has exactly the right firmness...

and exactly the right cush. It's my first new bed since the eighties I've told everyone about Casper and how I researched beds on Consumer's Reports. I couldn't be happier.

Debra B.

Snow

This mattress is exceptional.

It is the perfect mix of soft and firm, and I sleep so well at night. The cooling effect is also unbelievable. I will definitely purchase another in the future.

Kaitlin L.

Snow

Dreaming peacefully every night.

From the time we tried the mattress at the store, we were hooked. The innerspring mattress with the soft foam layers, offer a night's sleep that feels perfect. After 6-weeks, we're sleeping and dreaming peacefully every night.

Reviews

We like the mattress. I

"We like the mattress. I wish it was firmer. It would be nice to know exactly which mattress was built for firmness. Hearing firm is customer dependent isn’t helpful. It should be 100% clear with a sign - level of firmness."

— Marie H. (4/5)

My husband and I are

"My husband and I are absolutely loving our new Casper mattress. I got to test it out first as he was in the hospital when we ordered it. He needed something to come home to that he was going to be able to sleep comfortably on after he had major surgery. We are very happy with choosing a Casper mattress."

— Rebecca R. (5/5)

Casper products are top notch

"Casper products are top notch as is their customer service."

— Martha J. (5/5)

From the time we tried

"From the time we tried the mattress at the store, we were hooked. The innerspring mattress with the soft foam layers, offer a night's sleep that feels perfect. I like the support of the Casper in a standard mattress height, so all of the added foam pads can go and I can sit comforably on the side of the bed. Plus the sheets fit better. After 6-weeks, we're sleeping and dreaming peacefully every night. We plan to allow the full 3-month test-run before tossing the old mattresses, but as of now, we're pretty certain that Casper is truly a keeper."

— Joyce H. (5/5)

"Loving the snow technology! My son always used to complain about hot bed and sheets and now he loves it!"

— Taryn S. (5/5)

Outstanding! Casper lived up to

"Outstanding! Casper lived up to its' promises. I now have a bed I truly cannot wait to get to at night. Thank you to the Casper team."

— Shela P. (5/5)

We ordered the split king

"We ordered the split king mattress and base configuration. We love the ability to adjust our head and feet and couldn’t be happier with the base. I do wish the mattress was a little softer but that’s my own preference, nothing to do with the mattress. I would like to see Casper offer a topper that adds thick softness while maintaining the cooling technology. Overall we love our purchase and the customer service with Casper is truly PHENOMENAL!!!"

— Chris S. (5/5)

It's a keeper. I'm coming

"It's a keeper. I'm coming from a Sealy Posturepedic Crown Jewel queen firm, probably 20 years old. I have moderately bad sleep apnea and am a bit overweight. It is necessary for me to sleep on my side to minimize airway obstruction. The shoulder and hip pain I was developing from this position is much better now. Despite the Snow being considered firm by your and Consumer Reports criteria, I find it softer than what I have been used to. It is harder to turn over during the night and there is more sag when sitting on the edge. I don't know if this suggests a more limited lifespan or not. Temperature wise it seems neutral. I much prefer a cooler sleep environment and have not noticed much difference among various mattresses at home vs hotels etc. All in all the pros weigh more than the cons and getting/setting up our first online mattress was essentially hassle-free. Thank you for this product. Robb Shrader"

— Robb S. (4/5)

This is a good mattress,

"This is a good mattress, though it is not heavy so moves around a bit on the adjustable foundation. Delivery was not a good experience. Mattress was left in driveway, in the rain, even though we paid for set up. The set up had to be scheduled separately…for a week later."

— Patriicia P. (4/5)

SnowHoliday

"After putting off replacing my worn mattress for a year, I took action during our Winter Snow/Cold snap and bought the Casper Snow mattress and a Casper pillow, and guess what? When I awake, my back is no longer stiff, my surgery shoulder is no longer sore and I seldom have the neck strain headaches that I used to. It was a double blessing that it all was delivered right to my porch! No snow excursions required."

Frequently Asked Questions

What makes the Snow the right choice for me?

Hot sleepers will enjoy all night temperature regulation.
Zoned Support™ made especially for side sleepers.
A medium feel thats comfortable for stomach and back sleepers

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.

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.

What is the Zoned Support™ Technology in Casper hybrid mattresses?

Zoned Support™ is engineered to keep your spine in ergonomic alignment by providing support where your body needs it most, with firmer foam under the hips, waist, and lower back. Zoned Support™ Max combines our firmer center foam with a second layer of precisely cut channels to cradle the natural curve of your body while adding support to your hips, waist, and lower back for the ultimate ergonomic relief with our hybrid memory foam design.

What is the Snow Technology used in Casper cooling mattresses?

From Casper Labs, our most advanced solution to nighttime overheating combines HeatDelete® Bands, Phase Change Material, and a QuickCool™ Cover to keep you comfortably cool from the moment you crawl into bed.

See more of our Cooling Collection here.

*HeatDelete® and QuickCool™ are registered trademarks of Casper Sleep Inc.

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.
