Assessed from the specification published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
Firm mattresses at this price often skimp on comfort layers, but the Leano adds a silk and polyester fibre blend plus dual density soft white fibres above its 1000 pocket springs, which means a little cushioning before you reach that firm support. Each spring sits in its own fabric pocket, so it responds to your movements rather than transferring them across the bed, helpful if you share with a restless partner. Relyon is a National Bed Federation Approved Brand and the mattress is handcrafted in the UK. Buying through Mattress Online, you get a 100-night trial, free delivery to most locations and a 10-year guarantee, though those terms are that retailer's own, so check before buying elsewhere.
Key Features & what's inside
- Damask cover. A finely woven, durable fabric that feels soft to the touch and doesn't retain heat. That matters on a firm mattress, where you sleep more on the surface than in it.
- Silk and polyester fibre blend. A blend of silk and polyester fibres sits beneath the cover for extra comfort and breathability. It takes a little of the edge off the firm feel.
- Soft white fibres. Dual density fibres, plush on one side and dense on the other, deliver the firm comfort while increasing airflow through the mattress. Better airflow means less heat building up overnight.
- Pocket springs. 1000 individual springs, each encased in its own fabric pocket, respond to your movements independently. You get support where you press down without disturbing the rest of the bed.

Who's it NOT for?
This is a genuinely firm mattress, so lightweight side sleepers may find it presses uncomfortably on shoulders and hips. If you want a plush, sink-in feel, or the deep contouring of memory foam, look elsewhere. Owner feedback also suggests the feel can vary with your bed base, so a slatted frame may give a different result than a divan.

How firm is the Relyon Leano 1000 mattress?
It's rated firm in the retailer listing. The fibre layers above the springs soften the surface slightly, but this suits back and front sleepers best. Some owners note the feel can vary depending on your bed base.
How many springs does the Relyon Leano 1000 have?
It contains 1000 individual pocket springs, each encased in its own fabric pocket. That means each spring moves independently, giving support tailored to how you lie and reducing motion transfer across the bed.
Does the Relyon Leano 1000 come with a trial and guarantee?
Mattress Online lists a 100-night trial and a 10-year guarantee. These are that retailer's own terms rather than a Relyon-wide offer, so if you buy elsewhere, check what that seller provides before ordering.
What sizes is the Relyon Leano 1000 available in?
Five UK sizes: Single, Small Double, Double, King and Super King, priced from £425 to £629. One owner did report their delivered mattress measuring slightly smaller than the stated dimensions, so it may be worth measuring on arrival.
How deep is the Relyon Leano 1000 mattress?
It's 27cm deep. That's enough for the comfort layers and pocket springs while still fitting most standard fitted sheets, though deep-pocket sheets will give a neater fit.
