The Bordley Natural 2750 is listed as medium to firm, so it sits on the supportive side without feeling like a board, and the natural fibres help with temperature regulation, which means less of the clammy warmth you can get with synthetic foams. At 25cm deep with 2750 pocket springs plus a layer of HD mini springs, there's a lot of engineering here. It comes in five sizes from single up to emperor. It's a step up in price from entry-level mattresses, but the materials go some way to justifying it.

Why should you choose this mattress?
This mattress pairs 2750 pocket springs with 1700 of Harrison Spinks' own HD mini springs, which means support that adjusts to your shape rather than pushing back uniformly. The fillings are natural, wool and hemp among them, and wool is genuinely breathable, so hot sleepers should notice a difference compared with memory foam. It carries a National Bed Federation Approved Brand badge and conforms to BS7177: 2008 for home use. Mattress Online lists a 100-night trial and a 5 year guarantee with this mattress, though those are the retailer's own terms rather than the brand's, so check before buying elsewhere. The medium to firm feel suits back and stomach sleepers, although it may feel firm at first.
Key features & layer details
Wool
A soft wool top layer that's naturally breathable, which means air can move freely rather than trapping heat around you. Wool also wicks moisture, a quiet advantage on warmer nights.
Natural fillings blend
Layers of wool and hemp blended with fibres, giving a soft, springy feel underneath you. These natural fillings help regulate temperature through the night.
HD mini springs
1700 of Harrison Spinks' own HD mini springs sit above the main unit, flexing to mould to your body's shape. In practice this means more precise, three-dimensional support around shoulders and hips.
Pocket Springs
The base unit is 2750 pocket springs, each moving independently, so the mattress adapts to your body rather than sagging as one piece. Independent movement also reduces the ripple you feel when a partner shifts.

Best suited for?
Back sleepers
The medium to firm feel and layer of HD mini springs give supportive, shape-hugging support under the back without the mattress feeling like a board.
Front sleepers
A medium to firm surface over 2750 pocket springs keeps the hips from sinking too far, which suits sleeping on your front.
Warm sleepers
Wool and hemp fillings are naturally breathable and wick moisture, which means less clammy heat through the night than you would get with memory foam.
Couples
Each of the 2750 pocket springs moves independently, which reduces the ripple you feel when a partner shifts or gets out of bed.
Eco-conscious buyers
Natural fillings such as wool and hemp make up the comfort layers, giving a springy feel without relying on synthetic foams.
If you sleep on your side and are on the lighter side, medium to firm support may feel a little unyielding around the shoulders. It's also not the pick for anyone wanting that sink-in memory foam hug, or shoppers on a tight budget.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
Is the Harrison Spinks Bordley Natural 2750 firm or medium?
The product page describes it as medium to firm, though owner reviews suggest it feels firm initially and softens over time. That makes it a sensible fit for back and stomach sleepers, while lightweight side sleepers may find it slightly too firm at first.
Does the Bordley Natural 2750 come with a trial period?
Mattress Online lists a 100-night trial with this mattress. That trial is the retailer's own offer rather than a Harrison Spinks policy, so if you buy from a different shop, check their returns terms before ordering.
How many springs does the Bordley Natural 2750 have?
It's listed with 2750 pocket springs plus a layer of 1700 HD mini springs. The retailer's page does note the spring count may differ slightly from what's stated, while confirming it's still the same mattress.
Is the Bordley Natural 2750 good for hot sleepers?
It should be. The top layer is breathable wool and the fillings include hemp, both of which help regulate temperature. Owner reviews on mattressonline.co.uk mention good cooling compared with memory foam alternatives.
What sizes does the Bordley Natural 2750 come in?
It's available in UK single, double, king, super king and emperor. The mattress is 25cm deep across the range.
