Mattresses – Extra Firm, Medium & Memory Foam
Your mattress is arguably the most important purchase you will make for your home. You spend roughly a third of your life lying on it, and the quality of your sleep directly affects your mood, concentration, physical health, and overall wellbeing. Despite this, many people hold onto an old mattress far longer than they should, often because shopping for a new one feels overwhelming.
At ZORA Beds, we keep things straightforward by offering a curated range of mattresses across all firmness levels and materials, each backed by free UK delivery and a 30-night comfort trial.
Matching Firmness to Your Sleep Style
Firmness is not simply a matter of personal preference — it also relates to your body weight, sleeping position, and any specific aches or pains you experience. Getting this right can mean the difference between waking refreshed and waking stiff.
An extra firm mattress provides a highly supportive surface with minimal give. This firmness level is particularly well suited to heavier individuals who need the extra structural support to prevent the spine from dipping into an unnatural curve during the night.
Back sleepers also tend to benefit from a firmer surface, as it keeps the hips and shoulders aligned with the rest of the body. If you have been advised by a physiotherapist or osteopath to seek firm support, an extra firm option is usually what they have in mind.
A medium firm mattress is the most versatile choice and works well for the majority of sleepers. It offers enough support to keep the spine properly aligned while providing enough cushioning to relieve pressure at the shoulders, hips, and knees.
Side sleepers, who make up the largest proportion of the population, generally find medium firmness the most comfortable because it allows the heavier parts of the body to sink slightly without collapsing too far into the mattress. Combination sleepers who switch between positions throughout the night also benefit from this middle-ground approach.
Memory Foam and Modern Materials
Memory foam has transformed the mattress market over the past two decades, and for good reason. A double mattress memory foam layer conforms to the shape of your body, distributing weight evenly and reducing pressure points that can cause numbness, tingling, or joint stiffness. This contouring effect is particularly beneficial for side sleepers and people with conditions like arthritis or sciatica.
Modern memory foam mattresses have evolved considerably from the early versions that some sleepers found uncomfortably warm. Today's formulations include open-cell structures and infused cooling gels that promote airflow and regulate temperature throughout the night.
Many of our memory foam options combine a comfort layer of foam with a supportive base of pocket springs, giving you the pressure-relieving benefits of foam alongside the responsive bounce and breathability of springs.
When selecting a double mattress memory foam model, consider the depth of the foam layer as well as the density. Higher-density foams tend to be more durable and provide more pronounced contouring, while lower-density options feel softer and more immediately yielding. Foam depth typically ranges from 5 cm in hybrid models to 20 cm or more in all-foam designs.
What to Look For When Buying
Beyond firmness and material, several other factors influence how well a mattress will perform for you over time.
-
Breathability matters. Look for covers with quilted or breathable panels, and consider models with air channels or convoluted foam layers if you tend to sleep warm.
-
Edge support affects usable surface area. Reinforced edges prevent the sides of the mattress from collapsing when you sit on the bed, which is especially important on larger sizes like king and super king.
-
Motion isolation is key for couples. Pocket spring and memory foam constructions absorb movement effectively, meaning you are less likely to be disturbed by a restless partner.
-
Handles make rotation easier. Built-in side handles may seem like a small detail, but they make a genuinely noticeable difference when it comes to flipping or rotating your mattress every few months.

Frequently Asked Questions
How do I know if I need an extra firm or medium firm mattress?
As a general rule, back sleepers and heavier individuals benefit from extra firm support, while side sleepers and lighter individuals are usually more comfortable on medium firmness. If you are unsure, a medium firm is the safest starting point.
How long does a memory foam mattress last?
A quality memory foam mattress typically lasts between seven and ten years with proper care. Rotating it head to foot every three to six months helps prevent uneven wear.
Does memory foam have a smell when new?
A slight off-gassing odour is normal when you first unbox a memory foam mattress. This usually dissipates within 24 to 48 hours, especially if the room is well ventilated.
Can a double memory foam mattress be used on a slatted bed frame?
Yes, but check that the slats are no more than 7 cm apart. Wider gaps can cause the foam to sag between slats over time. A solid or closely spaced base is ideal.
What does your 30-night comfort trial involve?
Sleep on your new mattress for up to 30 nights. If you are not satisfied with the comfort level, contact us to discuss an exchange. The trial is designed to give you a genuine opportunity to adjust, since it can take a few weeks to adapt to a new sleep surface.
