Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
This is a mattress for buyers who want the classic hybrid combination, foam comfort with pocket spring support, without a premium price. The 1000 Mirapocket springs (counted on the king size, and pro-rata for smaller sizes) react independently to weight and movement, which means less disturbance when a partner shifts in the night. The Purotex treatment, a natural probiotic that combats allergens, is a genuine plus if you're an allergy sufferer. It's single-sided, so you rotate rather than flip it, and Silentnight says the design is tested for durable, long-lasting support. The memory foam layer is fairly simple, but at this price the essentials are well covered.
Key Features & what's inside
- Memory Foam Comfort Layer. A responsive memory foam that gently moulds to your body's contours, which means it absorbs energy and eases built-up pressure at the hips and shoulders. You'll feel a slight cradling on the surface rather than a deep sink.
- Mirapocket Spring Support System. 1000 individually nested pocket springs (based on the king size, with the count varying pro-rata for other sizes) react independently to your body weight and movement. Silentnight states the zoned support is scientifically proven to help spinal alignment and posture.

Who's it NOT for?
If you prefer a soft, sink-in feel, the Medium/Firm rating will likely feel too solid, and lightweight side sleepers in particular may not press far enough into the memory foam. It's also single-sided, so anyone who wants a flippable mattress for even wear should look elsewhere.

How firm is the Silentnight Pocket Essentials 1000 Memory Mattress?
Silentnight rates it as Medium/Firm. That's a versatile feel that works for most back and combination sleepers, although lighter side sleepers may find it slightly too firm for full pressure relief at the shoulder.
Does the Silentnight Pocket Essentials 1000 come with a trial?
Yes. Silentnight offers a 60-night trial on this mattress, along with a 5-year guarantee, so you have two months to decide whether the feel suits you.
How many springs does the Pocket Essentials 1000 Memory have?
It contains 1000 individually nested Mirapocket springs. That count is based on the king size (150cm x 200cm), so smaller sizes contain proportionally fewer springs.
Can you flip the Silentnight Pocket Essentials 1000 Memory Mattress?
No, it's a single-sided design, so you rotate it rather than flip it. Silentnight says the design has been tested for durable, long-lasting support, so this shouldn't shorten its useful life.
Is the Silentnight Pocket Essentials 1000 good for allergy sufferers?
It comes with a Purotex treatment, a 100% natural probiotic that combats allergens, which makes it a reasonable pick if allergies disturb your sleep.
