Casper Cloud One

Cloud One is not a different mattress from The One — it is The One with a different top layer. Casper calls it Core+, a patent-pending comfort foam that adds a plusher, slower initial response while keeping the airflow characteristics of the standard breathable layer underneath.

In practice, the difference is roughly two points of firmness. The One measures around 6.5 out of 10; Cloud One measures around 4.5. That takes it from medium-firm to medium-soft, which is precisely the range most side sleepers need to let the shoulder settle without the hips following.

The zoned support layer is unchanged, and that is why the swap works. A lot of plush foam mattresses get soft everywhere and let the pelvis sag. Cloud One softens the contact surface while the zone under the hips stays firm, so the spine still tracks straight.

Weight is the limit. At around 250 pounds and up, sleepers compress through the Core+ layer and start to feel the firmer zoned foam beneath it, which defeats the point of buying the plush model. Heavier side sleepers should be looking at Dream Max instead — the 14-inch build has enough comfort layer to keep working under load.

Cooling is the other limit. Cloud One is not a hot mattress, but a plusher surface means more body contact and slightly more retained heat than The One. If you already sleep warm, the extra plushness will be noticeable in a bad way, and Snow is the correct answer.

Finally, if you move around a lot at night, understand that softer foam is slower to recover. Combination sleepers who flip four or five times a night usually prefer Dream's springier hybrid surface.

Casper's lineup is easier to read than it looks because it varies along only two axes: support depth and cooling. The One and Cloud One are the all-foam tier. Dream and Snow are the 12-inch hybrid tier. Dream Max and Snow Max are the 14-inch tier. Within each tier, the "Snow" name always means the cooling package — Snow Technology foam plus the QuickCool cool-to-the-touch cover.

So the decision is two questions. First: do you sleep hot? If night sweats or hot flashes wake you up, you want Snow or Snow Max and nothing else in the lineup will fix it. Second: do you have back, hip or shoulder pain, or do you weigh more than about 230 pounds? If yes, step up to the 14-inch Max tier for the thicker comfort layer and deeper coil unit.

If neither applies, Dream is the answer. It is the medium-feel hybrid that suits the widest range of sleepers, it has the coil edge support that Casper's foam beds lack, and at roughly $1,400 on promotion it is the best value in the range.

Only choose the all-foam tier if budget is the constraint or you specifically want a quiet, motion-isolating foam feel. Between the two, The One is medium-firm and suits back and stomach sleepers, while Cloud One's Core+ layer makes it the side-sleeper option.

Every Casper mattress ships free in a box with a 100-night risk-free trial and a 10-year limited warranty. Casper asks you to sleep on the mattress for at least 30 nights before starting a return, which is reasonable — foam and hybrid beds both change feel over the first few weeks as the layers finish expanding and your body adapts.

Returns are free and Casper arranges pickup or donation rather than making you re-box the mattress. That matters more on the 14-inch Max models, which are genuinely heavy and not something one person should wrestle down a staircase.

Optional white glove delivery is available at checkout if you want the old mattress hauled away and the new one set up in the room. On the Snow Max and Dream Max we think it is worth the add-on; on The One and Cloud One the box is manageable for two people.

One underrated Casper advantage: retail. Casper mattresses are in physical stores and in select retail partners, so unlike most bed-in-a-box brands you can lie on The One, Dream and Snow before ordering. If you are torn between firmness levels, spend fifteen minutes in a store and then buy online through whatever promotion is running.
