Casper Dream vs Sleep Number 360 c2 Smart Bed: What Actually Differs

The Casper Dream is a hybrid build, while the Sleep Number 360 c2 Smart Bed is a smart bed — that single difference drives most of the cooling, motion, and feel decisions below. The Casper Dream stands 12" tall versus 8" for the Sleep Number 360 c2 Smart Bed — a 4.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. Both sit at roughly 5.5/10 on the firmness scale — a medium feel — so neither one is the answer if you need a dramatically different support level. The single largest performance gap is in motion isolation: the Casper Dream rates noticeably higher than the Sleep Number 360 c2 Smart Bed, which is the deciding factor if that dimension is high on your list. On a Queen, the Sleep Number 360 c2 Smart Bed runs $909 versus $1,325 for the Casper Dream — roughly $416 (31%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about.

Which Is Better For Your Sleep Style?

Side sleepers
Casper Dream

Higher pressure-relief rating, which is what protects hip and shoulder contact points in the side position.

Back sleepers
Casper Dream

Firmness of 5.5/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 5/10).

Stomach sleepers
Casper Dream

Firmer at 5.5/10 vs 5/10 — stomach sleepers need the extra support to keep the pelvis from sinking and arching the lower back.

Hot sleepers
Spec not available

Cooling rating not available for one or both mattresses — spec not available.

Heavier sleepers (230+ lb)
Casper Dream

stronger perimeter / edge support — the two specs heavier sleepers should weight most.

Lighter sleepers (under 150 lb)
Sleep Number 360 c2 Smart Bed

Softer at 5/10 vs 5.5/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.

Couples / light sleepers
Casper Dream

Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.
