Why The Casper Mattress

The Casper is trusted by sleepers everywhere for optimal support and the perfect bit of bounce.

Soft cushioning, full-body comfort.
The Casper Plush all-foam mattress delivers a softer, more contouring feel that gently cushions pressure points while still providing the support needed for comfortable, aligned sleep.

Designed for all sleepers.
The Casper Plush is designed to comfortably support all sleep positions, with extra cushioning and pressure relief that side sleepers especially tend to prefer.
Frequently Asked Questions
Yes, memory foam mattresses are a great option for many people as they are known for being both soft and supportive. A memory foam mattress like The Casper offers excellent pressure relief, contouring to your body's shape and providing support where needed. This is especially beneficial for combination sleepers who change positions throughout the night. The Casper is designed to ensure optimal comfort and support for side, back, and stomach sleepers.
Yes, The Casper is designed to sleep cool. It features a Cooling Eco Knit Mattress Cover and a layer of AirScape® Cooling Foam, which is a perforated, breathable foam designed to promote airflow and move heat away from the body. The Casper Mattress is an excellent choice for hot sleepers.

The Casper Mattress is available in three firmness levels. Whether you prefer a Plush mattress, Medium mattress, or Firm mattress, you don't have to sacrifice great sleep to keep your body comfortable and supported just the way you like it.
What's the difference?
While all three models are made with quality materials and the same innovative AirScape® Cooling Foam, Pressure-Relieving Premium Memory Foam, and ProSupport High-Density Base Foam, there is a difference in the feel. The Casper Medium features the perfect balance of support and cushion, while the Plush version features softer foam layers to relieve pressure points for side sleepers, and the Firm version is made with firmer foam layers to ensure spinal alignment for stomach and back sleepers.
Step 1: Protect your mattress
We strongly recommend using a mattress protector to prevent damage to your Casper mattress (plus a protector makes cleaning simple—just remove and wash as needed). Check out the Casper Mattress Protector or Casper QuickCool™ Mattress Protector, both of which are waterproof and designed to shield your mattress against stains, dirt, and wear.
Step 2: Keep it clean
No protector? Just spot clean gently with mild detergent and water, and let it air dry.
Step 3: Rotate to maintain
Rotate your mattress 180 degrees every three to six months to ensure it wears evenly. Do not flip it—Casper mattresses are designed with a specific top and bottom.

The Casper Plush is best for sleepers who prefer a softer, more contouring feel with extra pressure relief. Its plush design gently cushions the body, making it especially well suited for side sleepers, who often need added comfort around the shoulders and hips. It’s also a good fit for anyone who enjoys a “sink-in” feel without sacrificing supportive alignment.
The Casper Medium is best for sleepers looking for a balanced feel that combines cushioning comfort with reliable support. Its medium feel is designed to work well for a wide range of sleep positions, making it a versatile choice for combination sleepers and couples with different comfort preferences. It offers enough softness to relieve pressure while still helping keep the spine comfortably aligned.
The Casper Firm is best for sleepers who prefer a more supportive, stable sleep surface with minimal sink. Its firmer feel is especially well suited for back and stomach sleepers, who typically benefit from extra support to help maintain proper spinal alignment throughout the night. It’s also a great option for sleepers who prefer a more lifted feel rather than deep contouring.
Inspired by the first mattress that pioneered the bed-in-a-box category, The Casper is an upgraded take on the original memory foam mattress. Designed exclusively for Casper, it combines premium comfort foams, enhanced cooling features, and a high-quality cover to deliver a more comfortable, supportive, and refreshing sleep experience, all with the convenience of easy delivery to your door.
