Avocado Green Mattress vs Casper The One: What Actually Differs

The Avocado Green Mattress is a hybrid build, while the Casper The One is a memory foam — that single difference drives most of the cooling, motion, and feel decisions below. The Avocado Green Mattress stands 13" tall versus 11" for the Casper The One — a 2.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Avocado Green Mattress is the firmer of the two at 7/10 (medium-firm), and the Casper The One sits at 6/10 (medium-firm) — a meaningful enough gap that sleeper position and weight should drive the choice. The single largest performance gap is in motion isolation: the Casper The One rates noticeably higher than the Avocado Green Mattress, which is the deciding factor if that dimension is high on your list. On a Queen, the Casper The One runs $799 versus $2,549 for the Avocado Green Mattress — roughly $1,750 (69%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about. Trial periods aren't symmetrical either: the Avocado Green Mattress ships with a 365-night sleep trial versus 100 nights for the Casper The One, giving you a longer in-home runway to send it back if the feel doesn't land.

Which Is Better For Your Sleep Style?

Side sleepers
Either works

Both rate the same for pressure relief — choose on firmness instead (side sleepers usually prefer the softer of the two: Casper The One at 6/10).

Back sleepers
Casper The One

Firmness of 6/10 is closer to the medium-firm sweet spot back sleepers need for lumbar support (vs 7/10).

Stomach sleepers
Avocado Green Mattress

Firmer at 7/10 vs 6/10 — 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)
Avocado Green Mattress

better long-term durability and stronger perimeter / edge support — the two specs heavier sleepers should weight most.

Lighter sleepers (under 150 lb)
Casper The One

Softer at 6/10 vs 7/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.

Couples / light sleepers
Casper The One

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