Choose the Rufford if you want a genuinely firm mattress that doesn't feel like a board. The memory foam layer moulds around your shape to soften pressure points, while two fibre layers underneath reinforce the firm feel, which means you get support first with comfort layered on top. The pocket springs move independently, so a restless partner is less likely to disturb you, and the firmer outer rows limit that dipping sensation when you sit on the edge. Relyon is a National Bed Federation Approved Brand and the mattress conforms to BS7177: 2008 for fire resistance. Yes, it's a firm surface that won't suit everyone, but for those who want it, this is a well-built version of it.
Key Features & what's inside
- Knitted cover. A soft knitted finish that adds a touch of cosiness, which means the firm surface underneath doesn't feel harsh against you. It's designed for airflow and breathability, helpful if you tend to sleep warm.
- Memory foam layer. A 5cm layer of memory foam that adapts to your body and moulds around your shape. This is what softens the firm feel at pressure points like hips and shoulders.
- Soft white fibre layer. A small fibre layer that works with the tufted finish to smooth out the sleeping surface. You'll feel it as a slightly softer top rather than foam sitting straight on firm padding.
- Dense soft white fibre layer. Densely packed fibres that reinforce the firmness of the mattress. This is where the firm character really comes from, sitting between the comfort layers and the springs.
- Pocket springs. 1,500 individual springs encased in cloth pockets, so each one responds to your body independently and movement transfers less across the bed. Firmer springs on the outer rows, which Relyon calls Calibar Edge, limit dipping when you sit or sleep near the side.

Who's it NOT for?
If you sleep mainly on your side, particularly if you're lightweight, this is probably too firm: your shoulder and hip may not sink in enough for comfortable alignment. It's also not the pick if you like a plush, sink-in feel, as the memory foam here softens a firm surface rather than creating a soft one.

How firm is the Relyon Rufford Memory 1500 mattress?
It's rated firm. The dense fibre layer and pocket springs give a solid, supportive feel, while the 5cm memory foam layer adds contouring so it isn't rigid against your body. It suits back and front sleepers best; committed side sleepers may find it a little too firm.
Does the Relyon Rufford come with a trial period?
Mattress Online lists a 100-night trial on this mattress. That trial is the retailer's own offer rather than a Relyon policy, so if you buy elsewhere, check that retailer's terms before ordering.
How many springs does the Relyon Rufford Memory 1500 have?
It contains 1,500 pocket springs, each encased in its own cloth pocket so it responds to your body independently. The outer rows use firmer springs, which Relyon calls Calibar Edge, to limit dipping at the sides of the bed.
What guarantee does the Relyon Rufford mattress have?
Mattress Online lists a 10 year guarantee on this mattress. As that's stated on a retailer's page, it's sensible to confirm the guarantee terms with whichever retailer you buy from.
What sizes is the Relyon Rufford available in?
It comes in UK Single, Small Double, Double, King and Super King, with prices ranging from £675 to £1,416 depending on size. The mattress is 26cm deep.
