Need Help Deciding?
For most sleepers, we recommend the Avocado Vegan Mattress - Medium over the Casper The One. It scores higher in cooling, pressure relief, edge support; decide whether those advantages justify the $1,500 Queen premium ($2,399 vs $899). The Casper The One is the better choice only if budget is paramount — it saves roughly $1500.
Avocado Vegan Mattress - Medium vs Casper The One: What Actually Differs
The Avocado Vegan Mattress - Medium is a hybrid build, while the Casper The One is a memory foam — that construction difference drives most of the cooling, motion, and feel decisions below. Profile-wise they're almost identical — the Avocado Vegan Mattress - Medium measures 11" and the Casper The One measures 11", so neither will dictate your sheet depth or bed-frame compatibility. Their firmness is close but not identical: the Avocado Vegan Mattress - Medium is 6/10 and the Casper The One is 6.5/10. Both land near a medium-firm feel, so the half-point difference is less decisive than their construction and pressure response. The single largest performance gap is in edge support: the Avocado Vegan Mattress - Medium rates noticeably higher than the Casper The One, which is the deciding factor if that dimension is high on your list. On a Queen, the Casper The One runs $899 versus $2,399 for the Avocado Vegan Mattress - Medium — roughly $1,500 (63%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about. The linked-seller trial periods aren't symmetrical either: the Avocado Vegan Mattress - Medium is listed with 1-year trial at Avocado; 30-night minimum; $99 return fee, versus 100 nights at Casper; returns after 30 nights; free eligible return for the Casper The One.
Which Is Better For Your Sleep Style?
Higher pressure-relief rating, which is what protects hip and shoulder contact points in the side position.
Medium includes the option closest to a balanced medium feel for back sleepers (vs Medium-Firm).
Medium-Firm includes the firmer published option (vs Medium), which may better suit shoppers who prefer more surface support.
Stronger cooling rating, which matters most for sleepers who run hot or live in warm climates.
better long-term durability and stronger perimeter / edge support — the two specs heavier sleepers should weigh most.
Medium includes the softer published option (vs Medium-Firm), which can make contouring easier for lighter sleepers.
Higher motion-isolation rating, which means less disturbance when a partner moves or gets out of bed.

Avocado Vegan Mattress - Medium
Strengths
- ✓The wool-free build substitutes organic cotton batting and carries Vegan Action and PETA approval, giving animal-material-avoidant shoppers a specific alternative to the Green line
- ✓Three inches of organic Dunlop latex create a buoyant medium surface for back, stomach, and combination sleepers without the slow sink of memory foam
- ✓The current support family uses up to 1,379 individually wrapped coils and three wire gauges across seven zones to tune the perimeter and ergonomic support
- ✓Medium delivers the core vegan material package without Plush's added two inches of latex, taller profile, and price premium
Considerations
- —Side sleepers who need deeper shoulder and hip cushioning should compare Vegan Plush instead of assuming the shared materials create the same feel
- —Wool-free does not mean foam-free or spring-free; this model still uses Dunlop latex over a pocket-coil support unit
- —The 118-pound Queen is heavier than Green Medium and can require two people for setup or rotation
Casper The One
Strengths
- ✓Three-layer foam build with Casper Core support
- ✓Strong motion isolation for an all-foam bed
- ✓Split King available
Considerations
- —No coil edge feel
- —No active Snow cooling package
- —Medium-firm feel is less plush than Cloud One
