The natural fillings are the main draw here. British Cheviot wool, which is fully traceable from farm to shop, helps regulate temperature and adds a natural bounce, so if you're a hot sleeper this should feel less stuffy than an all-foam alternative. Cashmere and silk add a softer surface feel above the firm spring unit. The 2000 pocket springs move independently, which means your body gets support where it needs it and you'll feel less of a partner's movement. From £619, that's a reasonable price for this level of natural filling, at the cost of a shorter guarantee than some brands offer. It suits back and front sleepers who like a firm base best.
Key Features & what's inside
- Damask Cover. A breathable Belgian damask fabric cover. It lets air move through the sleep surface, which helps you stay cooler through the night.
- Natural Silk Layer. A soft, lightweight natural silk layer sitting near the surface. It adds a gentle, comfortable feel over the firmer materials below.
- Authentic Traceable British Wool. Wool from British Cheviot sheep, traceable from farm to shop, chosen for a fleece that's strong yet soft. It provides a natural bounce and helps regulate your temperature, so you're less likely to overheat.
- Cashmere. A rare filling that's softer and finer than wool, typically reserved for higher quality mattresses. It adds a touch of surface softness to what is otherwise a firm mattress.
- 2000 Pocket Springs. Each spring sits in its own fabric pocket, which means they work independently and respond to your body's shape rather than moving as one unit. That gives better pressure relief and less motion transfer between partners.

Who's it NOT for?
This is a firm mattress, so lightweight side sleepers may find it too unyielding at the shoulder and hip. If you prefer a cushioned, hugging feel, memory foam or a softer hybrid would suit you better. The 5-year guarantee is also shorter than some brands offer, which may matter if longevity reassurance is a priority.
Highgrove Ashbourne Ortho 2000 Pocket Natural Mattress
View all mattresses
How firm is the Highgrove Ashbourne Ortho 2000 mattress?
It's rated firm. That generally suits back and front sleepers, and heavier people who need more support. Lightweight side sleepers may find it a little too firm, although the silk, wool and cashmere layers do soften the surface feel slightly.
How many springs does the Highgrove Ashbourne Ortho 2000 have?
It has 2000 pocket springs, each housed in its own fabric pocket. They compress independently, which means the mattress responds to your body shape and transfers less movement across the bed if you share with a partner.
What is the Highgrove Ashbourne Ortho 2000 made of?
It combines a breathable Belgian damask cover with a natural silk layer, 100% traceable British Cheviot wool, cashmere and 2000 pocket springs. The mattress is 33cm deep, made in the UK by an NBF-approved manufacturer, and meets the BS7177: 2008 fire resistance standard for domestic use.
Does the Highgrove Ashbourne Ortho 2000 come with a guarantee?
Yes, MattressNextDay lists a 5-year Highgrove guarantee on this mattress. That's shorter than some brands offer, so factor it in if long-term cover matters to you. No trial period is stated on the listing.
How much does the Highgrove Ashbourne Ortho 2000 cost?
Prices run from £619 to £799 depending on size, starting at £619.00. It's available in UK Single, Double, King and Super King. Given the natural fillings, that pricing is honest rather than cheap: you're paying for wool, cashmere and silk rather than synthetic layers.
