Best Mattress for Back Sleepers in the UK
Back sleepers need a mattress that keeps the spine in its natural alignment, supporting the lower back curve while cushioning the shoulders and hips. In the UK, this usually means choosing a medium-firm mattress in sizes from 135x190cm for a double up to 180x200cm for a super king, with a combination of pocket springs and memory foam or latex layers proving most effective for even weight distribution.
Why Back Sleepers Need Specific Support
When you sleep on your back, gravity pulls the pelvis downward. Without adequate lumbar support the lower back can flatten, causing pressure on discs and muscles. A suitable mattress should allow the shoulders and pelvis to sink slightly while the lumbar area remains supported. UK fire safety regulations require all mattresses to meet BS 7177; this does not affect support but confirms every product sold here has passed the necessary tests.
Practical checklist before buying:
- Measure your bed frame exactly – UK double is 135x190cm, king 150x200cm, super king 180x200cm. EU sizes such as 140x200cm will not fit UK frames.
- Decide on firmness: most back sleepers of average build prefer medium-firm.
- Check total mattress depth against your bed frame sides; deeper mattresses reduce the visible frame height.
- Consider partner disturbance – pocket sprung constructions minimise motion transfer.
Best Mattress Types for Back Sleepers
Pocket sprung mattresses offer targeted support because each spring moves independently. Hybrid mattresses add a layer of memory foam or latex on top for pressure relief. Memory foam mattresses alone can work but sometimes feel too enveloping for back sleepers who want quicker response. Open coil mattresses are cheaper but provide less zoned support and are better avoided if you suffer lower-back pain.
Pocket sprung mattresses remain the most popular choice for back sleepers across single 90x190cm to super king 180x200cm sizes.
Medium-Firm Mattresses
A medium-firm feel balances support and comfort. Look for models with reinforced centre zones. These prevent the hips sinking too far while still allowing the shoulders to settle. Medium firm mattresses are the largest category for this sleeper type.
Recommended Picks for Back Sleepers
From the ranges available, these four mattresses suit back sleepers particularly well. Always check the individual product page for current depth, exact firmness and suitability for your weight.
The Maxitex Diamond Dual Season 1000 Pocket Memory Mattress combines pocket springs with memory foam and a cooling gel layer. The dual-season design lets you flip between a cooler side in summer and a warmer side in winter, maintaining consistent lumbar support year-round.
The Maxitex Dream 1000 Pocket Memory Mattress uses pocket springs plus memory foam to cradle the spine’s natural curve. Its zoned construction gives extra support under the lumbar area, reducing the chance of waking with stiffness.
The Maxitex Cloud Pocket Sprung Pillow Top Memory Mattress features a pillow top that adds plush comfort without sacrificing the firm core needed for back alignment. Ideal if you like a softer surface feel but still require strong lumbar support.
The Noomi Bamboo Natural Latex Pocket Sprung Mattress pairs natural latex with pocket springs and bamboo cover. Latex offers responsive bounce and excellent spinal alignment for back sleepers who dislike the slower sink of memory foam. It is also naturally breathable, helping regulate temperature.
Size Guide for UK Back Sleepers
Choosing the correct UK mattress size prevents edge rolling and gives enough room to maintain your back-sleeping position. Here is a quick comparison:
| Size Name | Dimensions | Best For |
|---|---|---|
| Single | 90x190cm (3ft) | Children, teenagers, spare rooms |
| Small Double | 120x190cm (4ft) | Single adults wanting extra width |
| Double | 135x190cm (4ft6) | Couples where space is limited |
| King | 150x200cm (5ft) | Most couples – recommended minimum |
| Super King | 180x200cm (6ft) | Those wanting maximum space |
If you share the bed, a king size or larger reduces disturbance. For children, kids’ mattresses in 70x140cm cot-bed size should also follow the same medium-firm guidance once they move from a cot (60x120cm).
Orthopaedic and Hybrid Options
Orthopaedic mattresses are often firmer and incorporate extra lumbar reinforcement. They suit heavier back sleepers or those with existing back conditions, but can feel too hard for lighter users. Hybrid mattresses combine pocket springs with latex or memory foam and are stocked in the hybrid mattresses category. They usually offer the best of both worlds for back sleepers.
Natural and Eco-Friendly Choices
If you prefer natural materials, natural and eco-friendly mattresses using latex, wool or bamboo are excellent. The responsive nature of latex helps maintain spinal alignment without the “stuck” feeling some memory foam can create. These also meet the same UK fire safety standards as synthetic options.
Memory Foam and Gel Mattresses
Memory foam mattresses contour closely and can relieve pressure points. However, back sleepers sometimes find them too slow to respond when changing position at night. Gel-infused versions help with heat dissipation. If you choose memory foam, select a medium-firm model with pocket springs beneath the foam layer for proper lumbar support.
Practical Decision Rules
- If you weigh under 60kg, start with a medium rather than firm mattress.
- If you weigh over 95kg, consider orthopaedic or firmer pocket sprung options with higher spring counts.
- Always lie on the mattress in your normal back-sleeping position for at least 10 minutes in the showroom.
- Check the maximum mattress depth allowed by your bed frame – many divans state 25-30cm maximum.
- For bunk beds, remember the top bunk guard rail must rise at least 16cm above the mattress; choose thinner mattresses where necessary and never use for children under 6.
Visit the main mattresses section to filter by size – king size mattresses, double mattresses or single mattresses – and firmness. A good night’s sleep starts with correct spinal alignment; taking time to choose the right support pays off in reduced stiffness and better rest.

Frequently asked questions
Is a firm mattress always better for back sleepers?
Not necessarily. While very firm mattresses suit heavier people, most average-weight back sleepers in the UK prefer medium-firm options. Too firm can create pressure at the shoulders and heels, preventing the slight sinking needed for natural spinal curvature. Test in store by lying flat and checking whether your hand slides easily under the lower back.
How thick should a mattress be for good back support?
Mattress depth itself does not determine support; the internal construction does. However, 20-30cm total depth is common for pocket-sprung and hybrid models that include comfort layers. Shallower mattresses (under 18cm) can feel firmer overall. Always match depth to your bed frame so the sides do not obstruct movement.
Can children who sleep on their backs use the same mattress types?
Yes, but choose age-appropriate sizes. Cot mattresses are typically 60x120cm and cot-bed or toddler mattresses 70x140cm. Kids’ pocket sprung models from the Maxitex range provide the necessary support without being overly firm. Bunk beds must comply with BS EN 747; top bunks are unsuitable for children under 6 regardless of mattress type.
Do memory foam mattresses cause overheating for back sleepers?
Traditional memory foam can retain heat, but many modern versions include gel or open-cell foam to improve airflow. Back sleepers who generate more heat through full-body contact may prefer latex or hybrid mattresses with natural fibres. A breathable mattress protector can also help regulate temperature.
Should I buy a mattress topper if my current bed is too firm?
A mattress topper can add cushioning but will not fix poor underlying support. If the base mattress lacks lumbar reinforcement, a topper may simply increase sinkage in the wrong areas. For back sleepers it is usually better to replace the mattress entirely with a medium-firm pocket or hybrid model rather than layering additional foam.
