Continuous coils are made from a single long wire bent into many connected coils, so the whole unit moves together. Pocket coils are wrapped individually and move on their own. Continuous coils are durable, firm, and bouncy but transfer motion, while pocket coils isolate motion and contour better, which makes them the better choice for couples and pressure relief.
| Continuous coils | Pocket coils | |
|---|---|---|
| Construction | One continuous wire forming rows of coils | Separate coils each wrapped in fabric |
| Feel | Firm, bouncy, uniform | Contouring, responsive locally |
| Motion isolation | Weak, movement spreads | Strong |
| Durability | Very durable due to the connected structure | Durable, depends on coil quality |
| Cost | Lower | Higher |
The connected design of continuous coils makes them sturdy and inexpensive, which is why they appear in budget mattresses. The downside is that because everything is linked, movement on one side travels across the bed, and the surface conforms less to your body. Pocket coils solve both problems by letting each spring act alone, at a higher price.
Choose continuous coils if you want a firm, budget-friendly, bouncy bed and sleep alone. Choose pocket coils if you share the bed, want better pressure relief, or are a side sleeper. Compare pocket coils to the other traditional type in pocket vs Bonnell coils, and see how coil beds compare to foam and latex in our mattress types guide.

They are durable and affordable with a firm, bouncy feel, which some sleepers like. Their weakness is motion transfer and less contouring compared with pocket coils.
Yes, more than pocket coils. Because the wire is connected, movement on one side is felt on the other, which can disturb a partner.
Both can be durable. The connected structure of continuous coils is very sturdy, while pocket coil longevity depends on the quality of the individual coils.
