The Best Air Cushion: Roho Dry Flotation Technology
Based on over 45 years of research and individual experience, ROHO® DRY FLOATATION® Technology provides unparalleled performance in facilitating blood flow by fitting and matching the shape of an individual.
ROHO is the worldwide leader of seating solutions to prevent and treat pressure injuries including deep tissue injury while providing skin and soft tissue protection.

The Four Principles of ROHO® DRY FLOATATION®

1. Low Surface Tension

Roho Low Surface TensionThe ability of the surface to easily yield upon contact.

2. Constant Restoring Forces

Roho Constant Restoring ForcesFluid flotation provides even and constant forces at all points of contact.

3. Six Degrees of Freedom

Roho Six degrees of freedomThe freedom of movement in all directions.

4. Low Shear & Friction

Roho Low Shear and FrictionFriction acts to impede motion. Shearing occurs when opposite but parallel forces meet.

How to Choose The Correct Roho Cushion Size:

Roho Cushion Measurement Instructions

Cushion Height

Roho Cushion HeightThe height of the cushion without load and without possible edging or seat shell. The point of departure is a normally inflated cushion. 

Cushion Width

Roho Seat WidthCushion width measured from edge to edge without load.

Cushion Depth

Roho Cushion DepthCushion depth measured from edge to edge without load.

Seat Width

Roho Cushion WidthThe appropriate seat width for using the cushion.

Seat Depth

Roho Seat DepthThe appropriate seat width for using the cushion. 


Roho Effective HeightSpacing between the lower portion of the body and the top of the seat cushion or mattress. The effective height of DRY FLOATATION® (height for AIR FLOATATION products with AIR FLOATATION™ technology) makes assumptions regarding the depth to which the body sinks into the cushion. The deeper, the greater the contact surface and the lower the pressure per cm2 of skin.
