Need Help Deciding?
For most sleepers, we recommend the Layla Memory Foam over the Casper The One. Our catalog rates it higher for cooling, pressure relief, edge support; check current linked-seller prices and terms before deciding on value. The Casper The One is the better choice only if you have a strong preference for that brand's specific feel or design.
Casper The One vs Layla Memory Foam: What Actually Differs
Both the Casper The One and Layla Memory Foam are memory foam mattresses, so the real differences come down to firmness tuning, performance ratings, and price rather than construction type. Profile-wise they're almost identical — the Casper The One measures 11" and the Layla Memory Foam measures 10.5", so neither will dictate your sheet depth or bed-frame compatibility. The Casper The One is the firmer of the two at 6.5/10 (medium-firm), and the Layla Memory Foam sits at 5.5/10 (medium-soft / medium-firm) — a meaningful enough gap that sleeper position and weight should drive the choice. The single largest performance gap is in pressure relief: the Layla Memory Foam rates noticeably higher than the Casper The One, which is the deciding factor if that dimension is high on your list.
Which Is Better For Your Sleep Style?
Higher pressure-relief rating, which is what protects hip and shoulder contact points in the side position.
Both include a medium-range feel (Medium-Firm vs Medium-Soft / Medium-Firm), so either can work for back sleepers.
Medium-Firm includes the firmer published option (vs Medium-Soft / Medium-Firm), 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.
stronger perimeter / edge support — the two specs heavier sleepers should weigh most.
Medium-Soft / Medium-Firm includes the softer published option (vs Medium-Firm), which can make contouring easier for lighter sleepers.
Motion isolation rated the same on both — neither has a transfer-disturbance edge.
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
Layla Memory Foam
Strengths
- ✓Two usable firmnesses let shoppers compare Medium-Soft and Medium-Firm at home without choosing one feel at checkout
- ✓Both sleep surfaces use 3.5-pound, 12-ILD copper memory foam, and the 1.65-pound, 30-ILD transition foam adds three-zone contouring
- ✓The 69-pound Queen is 34 pounds lighter than Layla Hybrid, while its continuous foam core makes it the stronger construction-based choice for quieter motion
- ✓The direct policy gives eligible buyers 120 nights after four weeks with no deducted return fee, backed by a lifetime limited warranty
Considerations
- —The solid foam core offers less through-mattress airflow and spring-assisted movement than Layla Hybrid's pocket-coil chamber
- —Layla does not publish a separate reinforced perimeter, so frequent edge sitting is a stronger reason to consider the Hybrid
- —CertiPUR-US applies to the flexible polyurethane foams; it is not an organic or whole-mattress certification
