Free Flow

Contains no fibre, and as the name suggests, it will move for at least 15-20 seconds before settling. Traditionally, this is how a waterbed was made, giving rise to the image that a waterbed will make you seasick.

Semi Motionless (50%)

Stops moving after about 8-10 seconds.  With only a small price increase as you step up through the range.

Waveless (75%)

With about 5-6 seconds movement, this mattress still has the feel of sleeping on a waterbed, but you are no longer disturbed by the movement of the water.

Motionless (95%)

The mattress has a little movement and it readjusts to your body shape. The motionless is a popular mattress.

Fully Stabilised (99%)

The mattress is filled with layers of fibre (baffles) which will absorb nearly all the waters movement making this mattress fully stabilised.

Dual System
With your choice of motion

  1. 1. Water displaced by one person does not affect the other. (Important if one person is of above average weight.
  2. 2. Although movement is slightly transmitted from one mattress to the other, it is greatly reduced.
  3. 3. Each mattress has its own temperature control.
