Silentnight Memory Cool™ Technology: What It Is & How It Works

1) What is Memory Cool™?

Memory Cool™ is Silentnight’s upgraded, cooling version of memory foam. It’s still a pressure-relieving comfort layer, but it has graphite particles running through it to make the surface up to 15% cooler than standard memory foam. You’ll see it on mattresses like the Silentnight Memory Cool 1000, Memory Cool 2000 Pillow Top and Memory Cool 3000 Box Top, each one combining that foam with different spring counts and tops.

2) How Memory Cool™ Works

a) Graphite-infused, temperature-managing foam

The star ingredient here is graphite-infused memory foam. Graphite conducts heat away from your body, so instead of warmth getting trapped around your shoulders and hips, it’s dispersed through the foam. That’s how Silentnight can claim a cooler feel compared with ordinary visco layers.

b) Pressure relief without losing that “hug”

Because Memory Cool™ is still memory foam at heart, it moulds to you: it spreads weight away from hotspots, softens around joints and gives that traditional, cocooned feel. It’s ideal for side sleepers and anyone who prefers a plusher top.

c) Paired with Mirapocket® (and sometimes Miracoil®) support

The foam sits on top of Silentnight’s own support systems. Most cooling models use 1000, 2000 or 3000 Mirapocket® springs — individually encased so they move separately, follow your shape and help stop partner disturbance. Some retailer-specific models may use Miracoil® continuous springs instead, for a slightly different price point and feel.

d) Breathable, soft-touch covers

To complement the cooler foam, Memory Cool™ mattresses are finished in breathable, soft-touch covers (and often a pillow-top or box-top). These help airflow around the mattress and prevent the surface from feeling clammy.

3) Key Benefits

• Cooler than standard memory foam: the graphite-infused layer is engineered to shed heat instead of storing it.
• Contour + support combo: you get a deep, sink-in comfort layer on top and pocket springs underneath to keep the spine aligned.
• Reduced partner disturbance: motion is absorbed by the foam and then further isolated by individually wrapped springs.
• Choice of spring counts: 1000 for balanced, everyday support; 2000 or 3000 (with box/pillow tops) for a more indulgent, plusher feel.
• Fresher-feeling surface: breathable borders and covers help moisture and warmth escape, so the mattress feels cleaner for longer.

4) Who Memory Cool™ May Suit

• Hot-or-warm sleepers who like memory foam but don’t want to overheat on it.
• Side sleepers who need the foam to give at the shoulder and hip.
• Couples who want good motion isolation without switching to an all-foam mattress.
• People with pressure-sensitive joints who’d benefit from a gentler top over a supportive spring core.
• Anyone upgrading from a basic memory foam mattress and looking for something that feels a bit more “airy” and premium.

5) Buying & Care Considerations

• Model differences: check the exact spec — some Memory Cool™ models are 1000-spring, others 2000 or 3000; some have pillow/box tops, others are straighter sided. This will change firmness, depth and price.
• Base compatibility: place on a supportive base. If you’re using slats, make sure the gaps are not excessive and everything is in good condition so the springs aren’t forced out of alignment.
• Rotation, not flipping: most of these mattresses are single sided. Rotate head-to-toe every few weeks at first, then every 1–2 months.
• Allergies & hygiene: look for models with breathable borders and an anti-allergy or easy-care finish if this is a priority.
