How to Choose the Right Sealy Mattress
Most Sealy® support systems are zoned, which means the coil layer is not set to a single firmness from head to foot. A zoned unit varies firmness by position along the bed, and Sealy concentrates the reinforcement in the centre third, where the hips and the small of the back load it hardest. That is the job Sealy gives the Posture Grid® Coil System featuring PostureSense™ Nano Coils. It is worth saying plainly that zoning is not a better surface than a uniform one, only a different one, and that it answers position rather than body weight: a surface that holds one firmness right across is exactly what many innerspring buyers are after. Posture Touch® Pocket Coils take the other route, wrapping each spring so it compresses on its own and follows your outline in smaller increments.
The SealyMAX Core System featuring SealyResponse™ PRO and SolidSupport™ Pocket Coils is the other name to know. Sealy positions it for spinal alignment and pressure relief rather than for one location inside the build, and the mechanism it publishes for SolidSupport is double packing: 117 coils in the centre third, so the busiest band of the bed carries more springs rather than stiffer wire. The SealyResponse™ HD Pocket Coil is a further pocket coil in the same family, and Sealy publishes no wire specification for it, so compare the models it appears in rather than reading anything into the letters. Above the coils two foams do two jobs: memory foam is viscoelastic and softens against body heat to mould around a shoulder, while resilient polyurethane foam springs straight back and suits transition and base layers that must hold their shape rather than cradle. Firmness comes as Firm, Medium and Plush.
Zoned by Position
A zoned unit varies firmness along the length of the bed rather than responding differently to two body weights. Our zoned lumbar support explainer shows how the zones are laid out.
Centre Third Reinforced
SolidSupport double packs 117 coils into the centre third, so the band under your hips carries more springs rather than stiffer wire. Sealy positions the SealyMAX Core System for spinal alignment and pressure relief.
Two Foams, Two Jobs
Memory foam moulds slowly and absorbs movement, while resilient polyurethane rebounds fast and holds structure. Most builds use both, each where its behaviour helps.
