Introducing the Silentnight British Wool 2400 Pocket Mattress
When it comes to getting a truly restful night’s sleep, having the right mattress can make all the difference. For UK shoppers searching for comfort, reliable support, and the luxury of natural materials, the Silentnight British Wool 2400 Pocket Mattress has emerged as a stand-out option. This in-depth review covers what sets this mattress apart, its features, who it suits best, and whether it’s the mattress you’ve been searching for.
What Is the Silentnight British Wool 2400 Pocket Mattress?

Design and Construction: What Makes It Special?
At the heart of this mattress is the Mirapocket spring system. With up to 2400 individual springs in king size, every area of your body receives targeted support. Each spring moves independently, minimising disturbance from a partner and supporting your unique shape and weight.
Above the springs sit generous layers of 100% British wool, renowned for its naturally breathable and moisture-wicking properties. Wool helps regulate sleep temperature for all seasons – insulation and warmth in winter, a cool and dry touch in the summer. Silentnight sources wool locally, supporting British farmers and eco-friendly practices.
The mattress is beautifully finished with a hand-tufted, quilted surface, which helps maintain structure and durability, preventing sagging over time. The edge of the mattress is reinforced for excellent support right to the sides, so you’ll never feel like you’re about to roll off.
Comfort and Support: How Does It Feel?
On lying down, the Silentnight British Wool 2400 Pocket Mattress greets you with a plush, lightly cushioned surface. The layers of natural wool create a welcoming softness, yet within seconds, the underlying spring system gently lifts and supports you – keeping your posture aligned and easing pressure points.
The medium tension suits those who like a balance between softness and support. You won’t experience that ‘sinking in’ feeling typical of deep memory foam, nor is it as firm as an orthopaedic or extra-firm mattress. It’s an inviting sweet spot for side and back sleepers, couples, and anyone wanting gentle cradling without deep contouring.
Who Will Benefit Most from This Mattress?
- Allergy sufferers: The British wool is naturally hypoallergenic, dust mite resistant, and chemical-free.
- Hot sleepers: Wool’s exceptional breathability helps wick away heat and sweat, keeping you cool.
- Couples: The 2400 individual pocket springs isolate movement, so you won’t disturb each other at night.
- Side and back sleepers: Medium tension relieves hip and shoulder pressure but keeps the spine supported.
- Eco-conscious buyers: The use of natural, locally sourced wool reduces the carbon footprint and supports British agriculture.
- People preferring natural fillings: If you find synthetic beds irritate your skin or overheat, natural wool solves both problems.
Why Choose British Wool?
UK shoppers increasingly look for natural, sustainable products in their homes. British wool has a unique structure that helps regulate both heat and moisture. Unlike synthetic fillings, wool absorbs humidity and releases it, reducing sweaty nights or that stuffy mattress feeling.
Wool also has a springy texture, adding cushioning and support to your bed while remaining resilient for years. As British wool is a renewable resource, it’s also more eco-friendly compared to synthetic foams. Plus, for those who deal with allergies, wool is naturally resistant to dust mites, mildew and bacteria.
Mirapocket Springs Explained
The 2400-count Mirapocket system is one of Silentnight’s signature innovations. Each spring is housed in its own fabric pocket, meaning it can respond independently to your body’s movement. This offers several advantages:
- Targeted support: Weight is distributed evenly, so you avoid roll-together with your sleeping partner.
- Motion isolation: You’re less likely to be disturbed by their movements—ideal for restless sleepers.
- Spine alignment: Springs cradle hips and shoulders while supporting your midsection, helping to relieve aches and pains.

Temperature Regulation: A Mattress for All Seasons
How well a mattress manages heat and moisture can be a deal-breaker, especially if you suffer from night sweats or hot flushes. Wool is one of the few natural materials that actively helps regulate your body temperature. As a natural insulator, it traps warmth on cold nights. Yet, thanks to its breathability, it also allows excess heat and moisture to escape on the hottest evenings.
This means you’ll sleep comfortably no matter the season — no more waking up sticky in summer or shivering in winter. Unlike foam, which can trap heat, wool adapts to your body’s needs.
Build Quality and Durability
Silentnight is renowned for its high British standards and craftsmanship. The British Wool 2400 Pocket Mattress is constructed to last, with rigorous quality checks throughout production. The hand-tufted surface keeps all internal fillings locked firmly in place, preventing lumps or shifting over time.
The pocket springs are made from high-tensile wire for years of resilient support. Wool fillings bounce back after every night’s sleep. The reinforced edge is especially useful if you need to sit on the side to dress, or if you share your bed and want to maximise sleeping space.
How Does It Compare to Other Silentnight Mattresses?
Silentnight’s product range covers memory foam, gel, and eco-fibre choices. The British Wool 2400 Pocket Mattress sits at the premium end thanks to its high spring count and all-natural fillings. For instance, compared to the Silentnight British Wool 1800 Pocket Mattress, the 2400 version delivers extra support and a more luxurious feel for heavier body types or those who want finer motion isolation.
Memory foam Silentnight mattresses, such as the Silentnight 1400 Pocket Memory Mattress, focus more on pressure relief with a ‘body-hug’ effect, which some love, but they may sleep hotter and lack the breathability of wool.

Value for Money: Is It Worth the Investment?
With a typical retail price of £1,090, but available from Mattress Online at £715.19 in king size, the British Wool 2400 combines everyday luxury with excellent long-term value. While it’s not the cheapest mattress available, the use of high-grade natural fillings, a premium pocket spring system and durable construction mean you’re making a sound investment in years of nightly comfort and well-being.

Unboxing and Mattress Setup Experience
Your Silentnight British Wool 2400 Pocket Mattress is delivered flat and ready to use, not rolled, thanks to its traditional construction. It will arrive via a two-person delivery with 2-3 weeks lead time. You’ll need help moving it to your room of choice, due to its high spring count and rich wool padding.
Once unwrapped, there’s only a subtle, clean scent of natural wool – there are no harsh off-gassing issues that you may experience with synthetic mattresses. The mattress fits UK king size bed frames, divans and slatted bases.
Care, Maintenance & Longevity
This mattress is single-sided – you don’t need to flip it, but regular rotation (head to foot) every few months will help maintain its shape and comfort. Thanks to the naturally resilient wool and reinforced spring system, the mattress is built to last for many years without indentations, dips, or sagging edges.
A mattress protector is recommended if you want to guard against spills or stains and prolong the fresh, natural feel. For advice on caring for your new mattress or cleaning natural fillings, see our How to Clean and Freshen a Mattress guide.
The Eco-Friendly Credentials
British wool is a sustainable, natural material. Choosing locally grown wool over imported or synthetic materials keeps your carbon footprint lower. Silentnight’s commitment to eco-friendly production and ethical sourcing ensures both the mattress and your conscience are clear. There are no chemical treatments or foam off-gassing, making it suitable for sensitive skin and eco-aware buyers.

The absence of chemical smell is a repeated positive, as is the mattress’s sturdy, long-lasting build.
