Casper vs Purple

Q: What about thermal regulation?

Casper: Highly breathable foams are designed to allow for fresh air to cool you all night long. Purple: Purple's grid is made of non-breathable polymers that can reduce air circulation, which may cause sweating and overheating.

Casper vs Purple

Better sleep is no gimmick.

You are not a grid.

Shop mattresses

Superior support, layer by layer.

When it comes to support, we know it’s what’s on the inside that counts.
That’s why we’ve continuously innovated our design and materials over ten years to create a support system that actually delivers better sleep—while Purple is confined to their grid.

Supports your curves

Zoned Support takes into account the shapes and curves of your body with a softer foam around the shoulders and a firmer foam under the hips, waist, and lower back.

Ultimate back support

Zoned Support Max divides the mattress into 7 support zones and two layers to give you support exactly where you need it.

With no variation from your head to toe, The Grid may not adapt to the curves and support needs of your body.

Their mattresses pass the egg test. Ours pass the people test.

We tested our mattresses side by side along with the Purple Flex and Purple Hybrid to see how they stacked up. When it comes to waking up refreshed, Casper always comes out on top.

Just right, every night.

We believe that every body deserves that perfect balance of softness and support, not just Goldilocks. Check out how Casper scored on the ergonomic scale.

What does ergonomics even mean?

Better sleep is off the grid.

How do we ensure your best rest? It’s simple. We follow two simple rules:
Everything in our mattress must help sleep, and must be tested, so there’s no room for gimmicks.

100% edge to edge comfort

Every Casper mattress has layers of comfort that cover the full surface of the mattress, extending edge-to-edge and providing a dreamy feel.

The grid only goes so far

Purple’s Grid mattress only covers 72% of the surface sleeping area, which means 28% isn’t giving you the support you need.

Word on the sheets

Elizabeth from Northampton, MA

"I recently bought a Purple Hybrid Premier 3 which was returned after 1 week because it caused me so much pain. I then ordered this mattress after a little research and it changed my life... stop thinking about it and just PUT IT IN YOUR CART! It totally changed my life."

Nicholas from Santa Fe, CA

"Good and firm! I got this after realizing the Purple mattress was too soft for me. This has helped my existing sciatica issue, which was present when I used the Purple."

Jennifer from Darian, GA

Sleeping with a partner? Purple may have you feeling blue.

Perfectly responsive

Casper mattresses are designed with individually-pocket flex coils to make sure you don’t feel your partner’s sleep hijinx.

When they move, you move

Purple’s grid pulls every time your partner rolls over, which can interrupt your sleep. Just like that.

Looking for the perfect mattress?

The Grid may work for some, but for most sleepers, choosing Casper is a no-brainer.
Why? Superior ergonomics, premium materials, reduced motion transfer, and 11 years of solving sleep problems.

A chart that highlights the differences between Casper and Purple mattresses in ergonomics and support, motion isolation, and all-night cooling. While Purple's mattresses are of a good quality, Casper's mattresses perform better in all of these areas.

Casper - Better Sleep, Better Buy

Our mattresses provide exceptional pressure relief, support, and cooling to over 2,000,000 happy sleepers. With innovative materials and design, Casper mattresses are meticulously human-engineered and designed with recycled polyester and upcycled cotton.

Purple - Breaking Down the Grid

Purple mattresses are made with their Grid™ technology, which is a solid polymer material that provides no obvious variation. Compared to Casper’s Dream Mattress, the Purple Mattress is more expensive and lacks zoned support that improves ergonomics.

Frequently asked questions

How does Casper compare to Purple for ergonomic support and spinal alignment?

Casper mattresses, especially Dream Max and hybrid models, use Zoned Support™Max—including up to 7 ergonomic zones —to target areas like shoulders, hips, and lower back for proper alignment.

Unlike Purple’s single-layer Grid technology, Casper is designed to adapt to your body’s curves and support you in any sleep position, delivering real, personalized ergonomic care.

How does Casper compare to Purple for comfort and feel?

Casper is engineered for the “just right” balance of softness and support every night. Our hybrid and foam models are thoughtfully layered for comfort that covers the entire sleeping surface edge-to-edge—so no matter where you rest, you’re supported. Purple’s Grid system feels unique but only covers about 72% of the surface, meaning some sleepers notice less support or comfort at the edges.

How do Casper and Purple differ in temperature regulation and cooling?

Casper’s Snow Max is engineered for advanced cooling, with HeatDelete® Bands, breathable foams, and a cool-to-the-touch cover that keeps you comfortable all night. While Purple’s Grid does promote airflow, Casper’s targeted cooling tech delivers consistent temperature control for hot sleepers and those who want reliable science behind their cool comfort.

How do Casper and Purple compare in warranty and sleep trial policies?

Casper offers a straightforward 100-night risk-free trial and a 10-year limited warranty, making returns and warranty claims easy and honest. Purple has similar policies, but always review the details—Casper makes protecting your sleep investment as easy as possible.

How do Casper and Purple compare in materials and manufacturing?

Casper mattresses are designed and assembled in the USA, with foams poured domestically for safety and comfort. Purple’s mattresses use their proprietary GelFlex Grid, made in the USA.

How do Casper and Purple mattresses compare in long-term durability?

Casper’s reinforced edges, hybrid spring systems, and multi-layer foam construction help maintain shape, comfort, and support year after year. Dream Max and Dream Hybrid are optimized for resilience and life-long performance. Purple’s grid offers bounce and airflow, but the breakdown of support or surface comfort over time compared to Casper’s robust designs is unclear.
