Why This Mattress

Why buy the Silentnight Geltex 3000 Astral - Medium Firm Mattress?

Every mattress is different. Scan for the ones that sound like you — if two or more fit, this is your mattress.

Best For
Back + Stomach
Back or front, never sure?
Steady, even support that keeps your spine level whether you settle on your back or your front.
Helps with
Disturbance
Partner tosses and turns?
Springs that move independently absorb motion, so a restless partner is far less likely to wake you.
Thermal Control
Cooling
Sleep hot?
Breathable layers draw heat away from you overnight, for a cooler sleep if you tend to run warm.
Thermal Control
All Season
Hot in July, cold in January?
A balanced build that doesn't run hot in summer or cold in winter, so it works all year round.
Suitability
Adults
Buying for a grown-up bed?
Built for full-grown sleepers, with the depth and support to take adult weight night after night.

Love this mattress, comfortable, no roll together, lots of space and full of support. It is deep at 40cm so new sheets were needed to fit, but well deserved for a fab mattress. Would recommend.
