Our take on the Casper Cloud One Mattress, California King

The Cloud One is Casper's softest all-foam mattress, built with a breathable knit cover over layers of polyurethane foam and a firmer base for support. It suits side sleepers and lighter sleepers who want a plush, pressure-relieving feel rather than a bouncy or firm bed. Compared with Casper's hybrid models, it has no coils, so it isolates motion well but sleeps warmer and offers less edge support. Reviewers generally like the cushioning and setup, while heavier sleepers and back sleepers often find it too soft.

Questions and answers

Is the Casper Cloud One good for side sleepers?
Yes. Its soft foam layers cushion the shoulders and hips, which is why side sleepers tend to rate it highest. Back and stomach sleepers usually want something firmer.
How does the Cloud One differ from Casper's hybrid mattresses?
The Cloud One is all foam with no coils. That gives it more sink and better motion isolation but less edge support and airflow than Casper's hybrid models.
Does the Cloud One need a box spring?
No. It works on a solid platform, a slatted frame or an adjustable base. A box spring is optional and mainly adds height.
Is the Cloud One good for couples?
Yes for motion isolation, since foam absorbs movement well. Heavier couples should note the softer feel and weaker edges.
How long does the Cloud One take to expand?
It usually expands within a day, though full loft can take up to 48 hours. Sleeping on it sooner is fine.
Is the California King size widely available in bedding?
Yes. California King sheets and protectors are common, though the size is longer and narrower than a standard King, so check fit.
Where is the Casper Cloud One Mattress, California King cheapest?
At The Home of Foam Mattress Superstore, for $1,288.99, 32% off, as of our latest check.
