Casper at Mattress Overstock
Every Casper mattress, from The One to Snow Max.
Three families. The One is all foam, with the same support from head to toe. Dream puts coils under Casper's Zoned Support, softer at the shoulders and firmer at the hips. Snow is Dream with Casper's cooling built in. Each family has a softer step-up.
Lay them down. Pick a support below and watch where the shoulder sinks and the hips are held. Drag the sleeper up and drop them, or roll them onto their back.

Layer names are Casper's. Casper does not publish layer depths, so heights are to scale and the split between layers is illustrative. Casper rates HeatDelete bands to move heat for 12+ hours, based on its testing against beds without them. Snow Max has 600 more grams per square meter of phase change material than Snow.
What people ask about Casper
Which Casper is for side sleepers?
Casper points side sleepers to its Zoned Support beds: Dream and Snow, or Dream Max and Snow Max for more. The foam is softer under the shoulder, so it can sink in, and firmer under the hips and waist. The One and Cloud One have the same support from head to toe, and Casper suggests The One for stomach sleepers.
What is the difference between Snow and Dream?
The support is the same: Zoned Support over wrapped coils. Snow adds Casper's cooling, a QuickCool cover, phase change material and graphite HeatDelete bands, three in Snow and six in Snow Max. Casper rates the bands to move heat for 12+ hours, from its own testing.
Is Cloud One softer than The One?
Yes. Both are 11 in. of foam. Cloud One has Casper Core+, foam pillars built into the base, which Casper says adds plushness. The One is medium-firm with a little bounce.
Can I lie on them before I buy?
Each row says whether that mattress is on a showroom floor. Choose your store at the top of the page and the rows name it. Lie on your side on The One, then on Dream, and pay attention to your shoulder.
