Secret Mattress vs Purple: Which Hybrid Mattress Wins for You?
Purple's gel grid feels unique but runs hot for some. Secret Mattress uses a hand-sewn hybrid build. Here's a feature-by-feature comparison.
Published 3/1/2025
Construction
Purple: A polymer 'GelFlex Grid' top layer over foam (in the original) or over individually wrapped coils (in Hybrid models). The grid is the brand's signature — it collapses under pressure points and stays firm everywhere else.
Secret Mattress: A hand-sewn hybrid build with contouring foam comfort layers over individually wrapped coils. The hand-sewn quilted top distributes pressure evenly without a polymer grid.
Feel
Purple: Bouncy and 'unique' — many sleepers either love it or can't get used to it. The grid feels firm-but-cushioned, with very little contouring.
Secret Mattress: A traditional medium-firm hybrid feel with cradle at the shoulder and hip and firm support under the lumbar. More familiar to most sleepers.
Cooling, motion, and edge support
Cooling: Purple's grid does allow airflow, but heavier sleepers report heat retention in the foam layers below. Hybrids with thinner foam tops (like Secret Mattress) generally sleep cooler.
Motion isolation: Purple is moderate — the grid transfers some motion. Secret Mattress's coils are individually wrapped to absorb partner movement.
Edge support: Both are strong on edges thanks to coil bases.
Trial, warranty, and US manufacturing
Both offer 100-night sleep trials and 10-year warranties.
Secret Mattress is hand-sewn and made in the USA. Purple manufactures in Utah and Georgia.
Pricing is comparable in the Queen range, with Secret Mattress typically including free shipping and white-glove options.
Frequently asked questions
- Is Purple or Secret Mattress better for side sleepers?
- Most side sleepers prefer the traditional contouring of a hand-sewn hybrid like Secret Mattress over Purple's polymer grid, which can feel too firm at the shoulder. If you've slept on a foam or hybrid bed before and liked it, Secret Mattress will feel more familiar.
- Which sleeps cooler?
- Hybrids with thinner foam comfort layers and a coil base — the Secret Mattress build — typically run cooler than Purple's thicker foam-over-grid construction.
