Pocket Sprung vs Memory Foam Mattress: Which Is Better for UK Sleepers?
Choosing between a pocket sprung mattress and a memory foam mattress is one of the most important decisions you'll make for your sleep. Both types are excellent — but they suit very different sleepers. This in-depth UK guide covers everything: construction, comfort, temperature, durability, back pain, couples, and price. By the end, you'll know exactly which is right for you.
What Is a Pocket Sprung Mattress?
A pocket sprung mattress is built around hundreds (sometimes thousands) of individually encased coil springs. Each spring sits inside its own fabric pocket and responds independently to pressure, providing targeted support across different zones of your body. Unlike older open-coil designs, pocket springs don't transfer movement across the mattress surface — making them an excellent choice for couples.
Pocket Sprung Pros
- Individually responsive support — each spring works independently for zoned comfort
- Excellent breathability — air circulates freely between springs, sleeping cooler
- Available in a wide range of tension levels from soft to extra-firm
- Durable — quality pocket springs maintain support for 8–10 years
- Suitable for all sleep positions with the correct tension selected
- Minimal partner disturbance — springs don't transfer movement across the surface
- Strong edge support — consistent feel right to the mattress border
Pocket Sprung Cons
- May not provide sufficient pressure relief for side sleepers with joint issues
- Higher spring counts (2000+) come at a premium price
- Can feel firmer than foam to some sleepers, especially initially
What Is a Memory Foam Mattress?
A memory foam mattress uses viscoelastic foam that responds to body heat and weight, contouring closely to your exact shape and redistributing pressure across a wider surface area. Originally developed by NASA in the 1960s, it's now one of the most popular mattress materials in the UK. The key characteristic is its slow response — it moulds around you, then gradually returns to its original form.
Memory Foam Pros
- Superior pressure relief — ideal for side sleepers and joint pain sufferers
- Strong motion isolation — minimal partner disturbance even on a shared mattress
- Body-contouring support — adapts to every sleeper's individual shape
- Silent — no spring noise whatsoever
- Hypoallergenic options available — dense foam resists dust mites
Memory Foam Cons
- Can retain heat — look for gel-infused or open-cell memory foam variants
- Less responsive feel — harder to move around on than springs
- Some sleepers find the cradling sensation too enveloping or claustrophobic
- Can feel softer initially, may require a settling-in period
Pocket Sprung vs Memory Foam: Head-to-Head Comparison
| Factor | Pocket Sprung | Memory Foam |
|---|---|---|
| Temperature Regulation | Excellent — natural airflow between springs | Can sleep warmer — gel variants help |
| Pressure Relief | Good — responsive support | Excellent — moulds to every curve |
| Motion Isolation | Very good — springs don't transfer across surface | Excellent — foam absorbs all movement |
| Edge Support | Excellent — consistent to the border | Variable — can feel soft near edges |
| Durability | 8–10 years for quality springs | 7–9 years for quality foam |
| Responsiveness | High — springs react immediately | Low — slow response, moulds gradually |
| Best For | Back/front sleepers, hot sleepers, combination sleepers | Side sleepers, joint pain, couples |
| Typical UK Price | £200–£1,500+ | £150–£1,000+ |
Which Is Better for Back Pain?
The answer depends on how you sleep. For back sleepers, a medium-firm pocket sprung mattress is typically recommended — it maintains natural spinal alignment without allowing the hips to sink. For side sleepers who experience lower back or hip pain, memory foam often works better because it relieves pressure at the shoulder and hip, allowing the spine to stay neutral. See our complete guide to the best mattress for back pain in the UK for a full breakdown.
Which Is Better for Couples?
Both types perform well for couples, but for different reasons. Memory foam leads on motion isolation — if your partner moves a lot at night, foam absorbs that movement almost completely. High-count pocket sprung mattresses are very close behind and have the advantage of sleeping cooler, which many couples prefer. If one partner is a hot sleeper and the other a restless sleeper, a hybrid mattress (combining both) is often the best solution.
Which Is Better for Hot Sleepers?
Pocket sprung mattresses win here. The gaps between the springs allow constant air circulation throughout the mattress, keeping the sleep surface cooler overnight. Standard memory foam retains body heat by design — though modern gel-infused and open-cell memory foam variants have significantly improved breathability. If you regularly overheat at night, pocket sprung or a cooling hybrid is the safer choice.
Sleep Position Guide
- Side sleepers: Memory foam or medium-soft pocket sprung — you need pressure relief at the hips and shoulders
- Back sleepers: Medium-firm pocket sprung for lumbar support and spinal alignment
- Front sleepers: Firm pocket sprung to prevent the lower back from arching
- Combination sleepers: Responsive pocket sprung or hybrid — memory foam can feel restrictive when changing position
Is Pocket Sprung or Memory Foam Better? The Verdict
Neither is universally better — the right choice depends on your sleep style, temperature preference, and budget.
- Choose pocket sprung if you sleep hot, prefer a responsive bouncy feel, sleep on your back or front, or are a combination sleeper who changes position frequently.
- Choose memory foam if you're a side sleeper, suffer from joint pain or pressure points, or share a bed with a restless partner.
- Choose a hybrid if you want the best of both worlds — pocket spring support with a memory foam comfort layer on top.

Frequently Asked Questions
Is memory foam or pocket sprung better for a bad back?
It depends on your sleep position. Back sleepers generally do better on medium-firm pocket sprung; side sleepers with back pain often benefit more from memory foam's pressure relief at the hips and shoulders.
Do pocket sprung mattresses last longer than memory foam?
Comparable quality pocket sprung mattresses typically last 8–10 years; memory foam 7–9 years. Both depend heavily on the quality of materials and regular rotation.
What is the difference between pocket sprung and memory foam?
Pocket sprung uses individual coil springs for responsive, bouncy support with excellent airflow. Memory foam uses viscoelastic foam that moulds slowly to your body for pressure relief with stronger motion isolation.
Can you get a mattress that combines both?
Yes — hybrid mattresses combine a pocket sprung base with a memory foam comfort layer on top, offering the support and breathability of springs with the pressure relief of foam.
