The Relyon Isabelle 2000's dual-spring build means the smaller springs contour to your body while the main unit does the supportive work underneath. Natural wool and soft white fibres sit above the springs, which helps with temperature regulation as well as comfort. At 29cm deep it has a reassuringly substantial feel, with a single up to a super king available. It suits sleepers who want proper firm support with a touch of natural softness on top.

Why should you choose this mattress?
Choose the Isabelle 2000 if you want a traditional firm pocket spring mattress from a National Bed Federation approved brand, without a memory foam feel. The individually cased springs adapt to movement independently, which means less disturbance when a partner shifts, and the mini pocket spring layer adds pressure relief that a plain firm mattress can lack. Wool and fibre fillings encourage airflow, useful if you tend to sleep warm. Buying through Mattress Online gets you their 100-night trial and free delivery to most locations, and the page states a 10-year guarantee. The starting price is fair for a handcrafted, 2,000-spring British mattress.
Key features & layer details
Damask cover
A damask cover, which is a finely woven and durable fabric, forms the sleep surface. It is soft to the touch.
Wool
A layer of natural wool sits beneath the cover for cosy, cushioned comfort. Wool also helps regulate temperature naturally.
Soft White Fibres
Soft white fibres increase airflow through the mattress. This works alongside the wool to keep the sleeping temperature steadier.
Mini Pocket Springs
Small, individually cased springs sit above the main spring unit. They add a gentle, contouring layer of pressure relief before you reach the firmer support below.
Pocket Springs
The main support comes from 2,000 individual springs encased in cloth pockets. Each spring moves independently, which means support is distributed to each part of your body and a restless partner is less likely to wake you.

Best suited for?
Couples
Individually cased springs move independently, which means a restless partner is less likely to wake you when they shift or turn over.
Warm sleepers
Natural wool and soft white fibres above the springs encourage airflow and help regulate temperature, so the bed should feel steadier through a warm night.
Back sleepers
A firm feel with 2,000 pocket springs underneath gives proper support, while the mini pocket spring layer adds some contouring where you need it.
Heavier sleepers
The 29cm depth and main unit of 2,000 individual springs do the supportive work, giving a reassuringly substantial feel without sinking in.
Front sleepers
Firm support from the pocket spring base helps keep you level on top, with a soft damask cover and wool layer for comfort.
This is a firm mattress, so lightweight side sleepers may find it presses on hips and shoulders rather than letting them sink in. One owner review also mentions the springs feeling weak at the edges, so if you sit on the side of the bed often, it may not be the best fit.
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 Relyon Isabelle 2000 mattress firm or soft?
It is rated firm. Sprung with 2,000 pocket springs plus a mini pocket spring layer, it gives solid support with some surface contouring. One owner review does describe the edges as feeling weaker than the firm rating suggests, so the firmness may feel less consistent right at the sides.
Does the Relyon Isabelle 2000 come with a trial period?
Mattress Online offers a 100-night trial. That trial is the retailer's own policy rather than a Relyon guarantee, so if you buy elsewhere the terms may differ.
How long is the guarantee on the Relyon Isabelle 2000?
The Mattress Online listing states a 10-year guarantee, which is a generous span and reflects the handcrafted UK build. As it appears on a retailer's page, it's sensible to confirm the guarantee terms with them at the point of purchase.
What sizes does the Relyon Isabelle 2000 come in?
Five UK sizes are available: single, small double, double, king and super king.
Is the Relyon Isabelle 2000 good for hot sleepers?
It should cope reasonably well. The wool layer regulates temperature naturally and the soft white fibres increase airflow through the mattress, while the open spring construction avoids the heat retention some foam mattresses suffer from.
