Firm Support That Works Through the Night

Wake up without that familiar ache across your lower back. The Keswick Ortho Memory Foam Mattress is built for sleepers who need real orthopaedic support - the kind that keeps your spine properly aligned whether you sleep on your back, side, or a combination of both.

The firm feel prevents unhealthy sinking, making it particularly well-suited to those who have found softer mattresses leave them feeling stiff in the morning.

Layered for Both Support and Comfort

Firm doesn't have to mean hard. The 14cm Eco foam base provides a stable, resilient foundation, while the 3cm reflex foam layer (Grade 33/190) ensures even weight distribution across the full surface.

On top, a 3cm memory foam comfort layer softens the feel just enough to cushion pressure points at the hips and shoulders without undermining the underlying orthopaedic support.

This layered approach means you get the postural benefits of a firm mattress alongside the pressure relief that helps you fall and stay asleep more comfortably.

A Bamboo Cover That Breathes

The smooth bamboo zip cover does more than look clean and crisp. Bamboo fibres are naturally moisture-wicking and more breathable than standard polyester covers, drawing heat and humidity away from the body during the night.

As a result, sleepers who tend to overheat will notice a more comfortable sleeping temperature even on a firm, supportive mattress. The cover removes fully for washing, making long-term hygiene effortless.

Delivered vacuum-packed and rolled, the Keswick expands to full size within a few hours of unboxing ready to use the same day it arrives. Alternatively, Browse our firm mattresses collection, or explore the wider mattress range to compare options across all firmness levels.

Why Memory Foam?

Memory foam layers provide comfort and support to your shoulders, back and hips, and works in harmony with your body to ensure that you are sleeping in the correct anatomical position, meaning you can wake feeling refreshed and free of any minor aches and pains.

Memory foam also offers relief for your pressure points which encourages healthy blood circulation, as well as reducing the need to toss and turn during the night, meaning a deeper and more restful sleep.

What is EcoFoam?

EcoFoam is a sustainable foam made from 100% recycled and re-engineered materials. Designed to be durable and resilient, it reacts to body weight and movement to deliver firm, orthopaedic-style support - making it a practical choice for anyone who needs a stable, even sleeping surface. It's naturally dust mite resistant and hypoallergenic, so it works well for allergy-sensitive sleepers too.

Spring-free by design, EcoFoam mattresses are completely silent and typically come with removable, washable covers for easy long-term maintenance.

Density/Firmness Rating - What's Best For You?

Each type of mattress varies by comfort grade, from soft to firm. Our density ratings (provided by the manufacturer) are to be used as a guide. Every comfort grade has its advantages, and the right one for you depends on your personal preferences but also your favoured sleeping position.

The Keswick Ortho Memory Foam mattress is rated as Firm.

Soft	Offers the least resistance, providing a gentle support base, contouring to your natural body shape. Perfect for side sleepers.
Medium	Gentle support system, conforming to the shape of your body. Great if you sleep on your side or front.
Firm	Provides essential support to maintain natural spinal alignment. Ideal for back or front sleepers.
Extra Firm	Provides increased support to maintain natural spinal alignment. Ideal for back or front sleepers. This extra support helps your body maintain good posture and prevents your back from curving.

Unboxing

• This mattresses is rolled and vacuum packed, so should be removed from the packaging as soon as possible after delivery
• Once unrolled, please allow up to 24 hours for the mattress to fully expand and recover to its intended shape and comfort level
• During the first few hours, the mattress may feel slightly firmer than expected – this will settle as it fully expands
• Some customers may notice a slight, harmless smell when first opening the mattress. This is known as off-gassing, which is normal for newly manufactured foam products. The smell is temporary and typically dissipates within a few hours to a couple of days.

We recommend placing the mattress in a well-ventilated room during this time to help the process
