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.

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.

Illustrations of people laying on Full and Queen size mattresses

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.

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?

Standard vs King Pillow Sizing
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.

Reviews

We are sleeping comfortably on

"We are sleeping comfortably on this mattress and we really like it. We slept on our previous mattress for fifty years. It was a Swedish latex foam mattress on a Danish platform bed. The has taken a little while for us to become used to our Casper and it's 11 inch thickness after sleeping on our old mattress for so many years. The relative softness of the edges or sides has required the most adjustment on our methods of getting into and out of bed. Our Casper has been otherwise perfect."

— Julian D. (4/5)

Have been sleeping for a

"Have been sleeping for a long time on Casper mattresses. Moved to a bigger place and needed more beds for the guest room. So bought new ones for ourselves and moved the ones we had to the guestroom. Comfort level: could not be better. Soft with support where needed. Slept better without any stiffness after the third day. I have an adjustable bed frame. Cost: Very competitive. On the lower end of other branded mattresses. I would recommend that Casper be given a try by everyone in the market for a new mattress. Returnable after atrial period within 100 days."

— Vashishta B. (5/5)

I love the Casper mattresses.

"I love the Casper mattresses. We purchased a queen from Costco and loved it then wanted the King and bought it from Casper website. It came sooner than expected and has let us have amazing rest feeling great the next morning."

— Katie B. (5/5)

Terrible. Never been picky about

"Terrible. Never been picky about beds or sleep until this mattress; causes back pain within 10 minutes of laying on it. Has only gotten worse over time. Don't listen to their 'hassle-free' return policy - they pass it off to a third party who doesn't cover your area, thus leaving you to dispose of your mattress on your own, on your own time. Then you have to hope they'll honor the refund (just like they honored the pickup). Awful company, awful product, STAY AWAY."

— Jacob W. (1/5)

Not only months of waiting

"Not only months of waiting (ordered bed frame in early July, still waiting for it in early September) but they delivered the wrong size 2 weeks ago and I’ve heard nothing back from Casper since. Customer Service was apologetic and professional, yet theft told me they get back to me within a few days to give me the info for an expedited correct order. No word after 2 weeks."

— Suzanne T. (1/5)

"Its comfy ...but disapointed that the side of mattress is not sturdy at all. When i sit on side to put socks on or just get out of bed you sink right in..."

Excellent customer service in Boca.

"Excellent customer service in Boca. Comfortable mattress. Fast delivery."

— Judy A. (5/5)

"The product is extremely comfortable; the delivery was fast and the product left in an area out of the rain."

— Carmen (5/5)

I had my previous Casper

"I had my previous Casper mattress for almost 9 years. I didn't want to let it go but it was time for an upgrade. I'm glad I did because this One is even better! Love it. It's much firmer when it needs to be but I still just melt into it."

— Sarah J. (5/5)

This is a nice bed.

"This is a nice bed. I like the fact that if you move around, the other person isn’t awakened by your movement."
