Mattresses are investments that should last for at least a decade, so choosing the right one for you takes a considerable amount of thought and research.

Two brands, Casper and Tempur-Pedic, make high-quality mattresses you may wish to consider.

Read on to learn how these two companies stack up against one another, plus the pros and cons of their most popular mattresses: the Casper Original and the Tempur-Pedic Adapt.


Casper Sleep Inc. was founded in 2014. It was one of the first manufacturers of compressed, bed-in-a-box mattresses.

There are three Casper mattress types to choose from. Each type is available as either an all-foam or hybrid mattress. Support levels range from soft plush to medium firm.

You can find our full review of Casper here.


The Tempur-Pedic brand is sold by Tempur-Sealy International Inc. Tempur-Pedic was originally founded in 1992 and merged with the Sealy Corporation in 2012.

There are five Tempur-Pedic mattress types with support levels ranging from soft to firm. Some are all-foam and others are hybrid, made from a combination of foam plus an innerspring layer.

Casper also uses recycled water bottles to make its mattress covers.

There are a few key differences between Tempur-Pedic and Casper:

  • Price. Casper mattresses are overall more affordable than Tempur-Pedic. There’s almost a $1,000 difference between each brand’s lowest-priced mattresses.
  • Customization. Tempur-Pedic mattresses offer more customization options than Casper models. With some Tempur-Pedic models, you can choose a “cooling level” while others let you choose your support level.
  • Delivery. Casper mattresses come delivered compressed in a box, while Tempur-Pedic mattresses come fully expanded. Tempur-Pedic’s white-glove delivery includes setup assistance, while Casper’s costs extra.

Casper Original Mattress

  • Height: 11 inches
  • Size options: Twin, twin XL, full, queen, king, California king
  • Firmness rating: Medium to medium firm
  • Warranty: 100-night, risk-free trial and 10-year limited warranty

The Casper Original Mattress is the company’s most popular mattress. You can choose to get the Casper Original in all foam or as a hybrid.

This mattress has three “support zones”: Softer foam around the shoulders and upper back is intended to provide comfort and cushioning, and firmer foam under the hips, waist, and lower back is designed to support spinal alignment.

The all-foam version of the Casper Original has a foam bottom base, whereas the hybrid version has an encased spring base, which may provide a better option for people who prefer a bit of bounce. The hybrid also has a firm border designed to support sleepers on the mattress’s edges as well.

Casper rates the hybrid version of this mattress as medium to medium firm, which might help ease nighttime aches and pains. A 2015 study indicates that medium-firm mattresses may be best for promoting sleep quality, sleep comfort, and spinal alignment.

Who is it for?

Many back, side, and stomach sleepers mention reductions in upper and lower back pain with this mattress. It’s worth noting that memory foam tends to feel softer for people with higher body weight.

Both versions are solid choices for couples looking for motion isolation.

Tempur-Pedic Tempur-Adapt

  • Height: 11 inches
  • Size options: Twin, twin long, full, queen, king, California king, split California king
  • Firmness rating: Medium
  • Warranty: 90-night sleep trial, free white-glove delivery, and 10-year warranty

The Tempur-Adapt is also available as an all-foam or hybrid mattress. It’s designed to provide pressure point relief and motion absorption. Remember the ad with the glass of wine on the bed? That’s Tempur-Pedic!

Each mattress is made from pressure-relieving material developed by NASA to absorb the G-force (gravitational force equivalent) of astronauts participating in shuttle launches.

Reviewers say the all-foam, or “medium,” version of the Adapt mattress provides a combination of support and a gentle, hug-like feel. The hybrid version’s bottom layer comprises 1,000 or more spring coils intended to add a layer of bounce.

Both versions of the Adapt feature Tempur-Pedic’s cool-to-the-touch mattress cover to encourage cooler sleep.

Who is it for?

Both versions of the Tempur-Adapt may be too soft for some stomach sleepers to feel comfortable on, but users say it’s a comfortable choice for side and back sleepers.


The Casper Original is delivered directly to your door, compressed and boxed.

You’ll need to remove it from its packaging and let it expand to its full size. This may take up to 2 days, although many customers mention that this process is nearly instantaneous.

Like most bed-in-a-box brands, you’ll likely experience an off-gassing scent for the first day or so. Letting your mattress sit on a porch or balcony for the first day can help.

If you prefer setup service, you may purchase it separately for a $149 in-home delivery and setup fee, provided you also bought a bed frame or a California king-size mattress.

As part of this service, Casper will dispose of your old mattress, as long as you live in one of the company’s in-home delivery and setup market areas.


Tempur-Pedic provides free white-glove delivery with the purchase of the Tempur-Adapt mattress. This includes delivery, setup, and removal of your old mattress and box spring, should you request it.

Due to COVID-19, white-glove delivery options may be limited in some locations.


The Casper Original has a 100-night, risk-free sleep trial, and a 10-year limited warranty.

If you choose to return or exchange, Casper can arrange a pickup of your mattress through a local charity or nonprofit organization, and refund you for the full amount.

In the event of an exchange, refunds and the 100-night sleep trial don’t apply for your second mattress.


The Tempur-Adapt comes with a 90-night sleep trial and 10-year warranty. You can make a return or exchange after you’ve had your mattress for 30 days, up until 90 days. The trial period begins as soon as your mattress is delivered.

This offer is only valid on mattresses purchased through the Tempur-Pedic website, flagship store, or through the company’s direct-order sales system. It’s not valid on mattresses purchased through third-party retailers, or on closeout mattresses.

Unlike Casper, if you do decide to return your mattress, a $175 return shipping fee may apply.

Casper Sleep has an endorsement from the American Chiropractic Association. This endorsement is given to a select group of companies that produce quality products, as determined by a review done by doctors of chiropractic and approval from the association’s board of governors.

Both Tempur-Pedic and Casper mattresses contain foams that are CertiPUR-US certified. This means they’re made with materials that are good for the ozone and environment, as regulated by the Consumer Product Safety Commission. The foams are free of chemicals like:

  • PBDE flame retardants
  • lead
  • mercury
  • formaldehyde
  • phthalates
  • heavy metals

And both Casper and Tempur-Pedic mattresses meet federal government standards for flammability deterrents, as governed by 16 CRF 1633 and 1632.

In 2020, investors filed a class-action lawsuit against Casper Sleep Inc. to cover financial losses.


Tempur-Sealy International Inc. has an A- business rating from the Better Business Bureau. Tempur-Pedic has a 2.6 (Poor) rating from Trustpilot.

The Casper Original and Tempur-Adapt are popular mattresses that are both available as all-foam or hybrids. They each come with at-home sleep trials and a 10-year warranty.
