| Bonnell Springs are made of high carbon steel wires which have good performance in tensile strength and hardness. | |
Our unique bonnell coil spring is derived from our special double coned design which assists in spreading and
distributing the weight throughtout the bed equally.The outer spring is specifically designed to be less firm than
the inner spring so that the mattress can ergonomically absorb the weight of your clients's different posture.The
inner spring is then firmer,so that weight is distributed to the support layer with efficiency.
