Difference between Bonnell Spring and Pocket Spring mattress

One question that every customer asks is what is the difference between Bonnell Spring and Pocket Spring? Here is a simple explanation that will help you to understand how they are different.

  • Bonnell spring system mattress is one of the earliest types of spring mattress technology in the market. Bonnell spring coils are described as inter-connected wire coil technology. Mattresses of this type tend to be firmer due to their inner coil structure. As the wires are inter-connected, this spring system tends to be more motion-sensitive. This means that when someone moves on one side of the bed, the person at the other end may feel the movement on the mattress as well. However, Pocket spring mattresses are made with springs, which are not interconnected. This prevents any movement. If one partner is turning and tossing on the bed, the other one may not feel the movement.
  • A Pocket Spring Mattresses is expensive than a Bonnell Spring Mattress.
  • Pocket mattresses can give support to various body curves but Bonnell mattresses cannot because the springs in the Bonnell mattress move together. However, in the Pocket mattress, the springs move individually.
  • Unlike the Bonnell spring system mattresses, Pocket spring mattresses have each coil unit encased in individual fabric Pockets. Such a spring system design reduces movement across the mattress when one person moves on one end of the mattress, reducing interruptions during sleep.
  • Pocket spring systems also provide sufficient support to the whole body with the individual pocket coils responding individually to different pressure points and weights of the body. Pocket mattresses are slightly softer than Bonnell mattresses
  • The air volume circulating inside the Pocket mattress ensures a good night’s sleep and a comfortable bed temperature. The major difference between both the mattresses is that the springs in the Bonell mattress are connected while the springs in the Pocket mattress are not connected.
