Open Coil Mattress Pros and Cons Explained
Open coil mattresses use a single continuous wire mesh of springs that are linked together. This traditional construction remains popular in the UK because it offers good value, strong edge support and reliable airflow, yet it can transmit more movement and provide less individual body support than newer pocket-sprung or memory foam designs.
What Is an Open Coil Mattress?
Open coil, also called Bonnell or continuous coil, features rows of hourglass-shaped springs connected by helical wires. The entire unit moves as one. Most UK open coil mattresses combine this spring unit with a layer of padding and a stitched damask cover. They meet the Furniture and Furnishings (Fire) (Safety) Regulations 1988 and are tested to BS 7177. Always check the exact specification on the product page.
Key Advantages of Open Coil Mattresses
The linked spring system creates a firm, supportive feel that many back and stomach sleepers prefer. Air circulates freely through the open structure, helping the mattress stay cooler than foam-only options. Edge support is usually firmer because the springs run right to the border. Budget prices make them attractive for spare rooms, rental properties and children’s beds. For example, the Maxitex Roma Open Coil Mattress delivers classic open coil support at an accessible price.
Practical checklist before buying an open coil mattress
- Confirm the exact UK size needed: small single 75x190 cm (2ft6), single 90x190 cm (3ft), small double 120x190 cm (4ft), double 135x190 cm (4ft6), king 150x200 cm (5ft), super king 180x200 cm (6ft).
- Decide on firmness – most open coil models sit in the medium to firm range; test in store if possible.
- Measure your bed frame to ensure at least 5 cm clearance on all sides for ventilation.
- Check the maximum mattress depth allowed by any bunk bed; top bunks must follow BS EN 747 with guard rails rising at least 16 cm above the mattress surface and are not recommended for children under 6.
Disadvantages Compared with Newer Constructions
Because all springs are wired together, movement from one side travels across the mattress. This can disturb a partner who wakes easily. Individual body contouring is limited, so pressure relief on shoulders and hips may feel less noticeable than on memory foam or pocket sprung models. Over many years the interconnected springs can develop body impressions more quickly if the mattress is rotated infrequently. Open coil also lacks the motion isolation of pocket sprung mattresses, where each spring sits in its own fabric pocket.
If you need better pressure relief, browse our Memory Foam Mattresses or Pocket Sprung Mattresses categories.
Open Coil vs Pocket Sprung – Direct Comparison
| Feature | Open Coil | Pocket Sprung |

| Body contouring | Basic | Targeted |
| Price point | Lower | Medium to higher |
| Airflow | Excellent | Good |
Use this table to decide which suits your household. Couples usually benefit from pocket sprung; single sleepers or budget-conscious buyers often choose open coil.
Who Should Choose an Open Coil Mattress?
Open coil suits back or stomach sleepers who want firm support and excellent ventilation. They work well in guest rooms, children’s bedrooms and for anyone on a tight budget. If you share a bed and one partner is a light sleeper, consider upgrading to pocket sprung. For children, open coil provides durable, breathable support; see our range of Kids' Open Coil Mattresses.
Care and Longevity Tips
Rotate your open coil mattress every 4–6 weeks to prevent sagging. Use a good quality mattress protector to guard against spills and dust mites. Vacuum the surface monthly. With proper care an open coil mattress typically lasts 7–10 years before the springs lose tension. Always follow the maximum depth stated by bunk-bed manufacturers to stay within BS EN 747 safety rules.
Choosing the Right Firmness and Size
UK shoppers should match firmness to body weight and sleeping position. Heavier adults (over 95 kg) often prefer firm open coil models; lighter sleepers may opt for medium. Check the full selection of Medium Firm Mattresses and Firm Mattresses. For larger rooms the King Size Mattresses or Super King Mattresses in open coil give extra width while keeping costs down.

Frequently asked questions
Are open coil mattresses suitable for bunk beds?
Yes, provided the top bunk meets BS EN 747. The guard rail must sit at least 16 cm above the mattress surface, so use the exact maximum depth stated by the bed maker. Open coil mattresses offer good airflow and firm support that many children prefer, but they are not recommended for children under 6 on the top bunk.
How do open coil mattresses compare with hybrid designs?
Hybrid mattresses combine pocket springs with thicker foam or latex layers for better pressure relief and motion isolation. Open coil versions are simpler, cheaper and cooler but transmit more movement. Choose hybrid if you need contouring; stick with open coil for value and ventilation.
Do open coil mattresses need a specific base?
They perform best on a slatted base with gaps no wider than 7 cm or on a solid divan. Avoid old sprung bases that can damage the coil unit. Always check the product page for recommended base types and ensure the frame matches the UK mattress size you select.
Can I use an open coil mattress on a adjustable bed?
Most open coil mattresses are not designed for frequent articulation. The linked springs can be stressed by repeated folding. Memory foam or pocket sprung models usually adapt better. If you need an adjustable option, look at hybrid or latex mattresses instead.
Are there eco-friendly open coil mattresses?
Traditional open coil designs use metal springs that are recyclable but often paired with synthetic fillings. For more natural options consider our <a href="https://www.bedkingdom.co.uk/mattresses/eco-friendly-mattresses.html">Natural and Eco-Friendly Mattresses</a> or latex hybrids that still offer some spring support.
