Silentnight Aloe Vera Portloe Miracoil Ortho Mattress

Assessed from the specification published by dreams.co.uk, captured November 2026, and from regular price comparison across our UK retail partners.

This is a mattress for people who want a very firm bed. The Miracoil spring system is zoned, which means support is shaped to different parts of your body rather than being the same everywhere. The edge-to-edge design is meant to minimise partner disturbance, so it should suit couples who move around. Breathe fibres regulate temperature, which helps if you tend to overheat. The aloe vera infused cover is hypoallergenic and antibacterial, a sensible detail if you're sensitive to allergens. It suits most back sleepers who like firm support, although anyone who wants a softer feel will find it too hard.

If you prefer sleeping on a soft or medium mattress, this might not be the best choice. It's rated extra firm, so there's very little give at the shoulders and hips, which can be uncomfortable for side sleepers and lighter sleepers. Silentnight doesn't publish a depth for this mattress, so check it suits your bed frame.

It can be. The edge-to-edge design is intended to minimise partner disturbance. The catch is the extra-firm feel: you both need to be happy sleeping on a very firm surface.
