Are Open Coil Mattresses Any Good? UK Review
Open coil mattresses are a solid choice for budget-conscious shoppers in the UK who need decent support without high costs. They use a single continuous wire mesh of springs that provide firm, responsive support and good edge strength, though they can transfer more movement than pocket sprung designs.
What Is an Open Coil Mattress?
Open coil, also called Bonnell or continuous coil, features one interconnected spring unit rather than individual pockets. The springs are hourglass-shaped and tied together, creating a uniform surface. Most UK open coil mattresses combine this with a layer of padding such as polyester or cotton. They meet the mandatory UK fire-safety standard BS 7177 and are widely available in all standard sizes: small single 75x190cm (2ft6), single 90x190cm (3ft), small double 120x190cm (4ft), double 135x190cm (4ft6), king 150x200cm (5ft) and super king 180x200cm (6ft).
Pros of Open Coil Mattresses
The main advantages are affordability and reliable support. The connected springs give a firmer feel that many back sleepers prefer. Air circulates freely through the coils, helping the mattress stay cooler than memory foam. Edge support is usually strong because the springs run to the border. They are lighter than pocket sprung or hybrid mattresses, making rotation and turning easier. For growing children, the firmer surface helps maintain spinal alignment.
Practical Checklist Before Buying an Open Coil Mattress
- Measure your bed frame exactly; allow 2-3cm clearance on all sides for easy fitting.
- Decide on firmness: most open coil models suit those who weigh under 85kg and prefer medium to firm support.
- Check total mattress depth on the product page; deeper models usually have more padding layers.
- Confirm the top-bunk guard rail will still rise at least 16cm above the mattress if used in a bunk bed meeting BS EN 747 (top bunks not recommended for children under 6).
- Plan to rotate the mattress head-to-foot every 3 months and flip it if both sides are identical.
Cons and Limitations
Movement transfer is the biggest drawback: because all springs are linked, one person shifting disturbs a partner. They offer less contouring than pocket sprung or memory foam, so side sleepers may find pressure points at shoulders and hips. They can squeak after a few years if the wire ties loosen. Not ideal for heavier sleepers above 100kg who may bottom out faster.
How Long Do Open Coil Mattresses Last?
With daily use, an open coil mattress typically lasts 5-7 years before support declines. Factors that shorten life include jumping on the bed, not rotating it, or using it without a protective cover. UK fire regulations require all mattresses to use flame-retardant fillings, which can compress over time. To maximise lifespan, use a good mattress protector and avoid storing heavy items on it. If you need longer durability, consider upgrading to pocket sprung designs.
Open Coil vs Pocket Sprung Mattresses
Open coil mattresses cost less and feel firmer with better airflow. Pocket sprung versions isolate each spring in its own fabric pocket, reducing motion transfer and offering better pressure relief. Choose open coil if your budget is tight and you sleep alone or prefer firmness. For couples or side sleepers, pocket sprung is worth the extra investment.

| Feature | Open Coil | Pocket Sprung |
|---|---|---|
| Price level | Budget | Mid-range |
| Motion transfer | Higher | Lower |
| Edge support | Good | Very good |
| Best for | Back sleepers, children | Couples, side sleepers |
Are Open Coil Mattresses Suitable for Children?
Yes, especially for bunk beds and growing kids. The firmer support helps developing spines and the lower price is practical for rooms that get heavy use. Always choose a model that leaves the top-bunk guard rail at least 16cm above the mattress surface and never use for children under 6 on the top bunk. Our Kids' Open Coil Mattresses (5 in stock) are designed for exactly this purpose. For cot and toddler sizes, common dimensions are 60x120cm for cots and 70x140cm for cot beds; see our Kids' Mattresses (35 in stock).

Frequently asked questions
Do open coil mattresses need flipping?
Many open coil mattresses are double-sided and should be flipped and rotated every 3 months to maintain even wear. Check the product page; single-sided versions only need rotating head to foot.
Are open coil mattresses good for heavy people?
They suit people up to around 85-90kg. Heavier sleepers may experience faster sagging because the interconnected springs share load across the whole unit. For weights above 100kg, pocket sprung or reinforced hybrid mattresses usually provide better long-term support.
Can you use an open coil mattress on a divan with storage drawers?
Yes, provided the divan has a solid base or sufficient slats (maximum 7cm gap). Open coil mattresses need a firm, flat platform. Avoid using them on very flexible bases as this can distort the spring unit and shorten lifespan.
How do I stop my open coil mattress from squeaking?
Squeaks usually come from loose wire ties or friction where springs meet the frame. Rotate the mattress regularly and ensure it sits squarely on the bed base. If the noise persists after 2-3 years it is often a sign the springs are fatiguing and replacement may be needed.
Is an open coil mattress better than memory foam for hot sleepers?
Usually yes. The open structure allows far more airflow than solid memory foam. However, adding thick memory layers reduces this benefit. Choose a model with minimal foam topping and always pair it with breathable cotton bedding for best cooling.
