The 

Rock King

®

 promotes resident satisfaction 

and positive outcomes through these unique 
features: 

‹

 

Rocking Motion:

 

The Rock King has a unique rocking feature 

that provides soothing comfort to the user which often has a 
calming effect.  The need for restraints may be eliminated or 
reduced.  Also, wellness is promoted when rocking by maintaining 
good posture and by shifting body weight slightly, thereby reducing 
seating pressure.

 

‹

 

Tilt-In-Space: 

This feature allows you to create a “deep wedge” 

by locking the chair in a semi-reclined position; degree of tilt is 
approximately 30º.  This position is desirable if you are attempting 
to reduce “slide out”, seating pressure or concerned about posture.

 

‹

 

Height adjustable seat:

 

This feature is useful in fitting the 

chair to the height of the person using it.  Most users will be fitted 
comfortably in the 

low

 position.  Taller users may require raising 

the seat which is easily done by with a ¾ inch socket on the 24-inch 
front wheels.  

Note: 

Lighter weight users may need to adjust 

rocking tension by lowering the back casters and raising the front 
seat height to facilitate easier rocking. Reverse for heavier users.

 

‹

 

Standard Footrests: 

Footrests can be vertically adjusted to 

accommodate the various positions of the chair (upright or 
reclined), and the leg length of the user. 

‹

 

Elevating Legrests (option):

 The elevating legrest is designed 

to be articulating (telescoping) to help prevent patient “foot drop” 
which can occur when foot plates cannot be kept in place

 

due to 

reduction in the knee angle. 

Note: Adjustment handles have a 

built in ratchet.  After tightening pull out to reposition. 

‹

 

Lateral Supports:

 

For those users requiring lateral support; 

side panels are included as part of the standard “kit” package.  

 

‹

 

Stability: 

The wheelbase on the Rock King is 9 inches longer 

than a standard wheelchair.  This additional length is more than 
ample to provide the necessary stability in either the rocking mode 
or tilt-in-space position.

 

‹

 

Seat Belt (option):

 For added security, a seat belt option (Fabric 

Safety Strap) may be placed around the waist of the patient and 
attached behind the back of the chair with either a buckle (Part 
#RY2019Y) or Velcro (Part #2019Y-1) attachment.

The Locking Lever 
shown in the 
‘neutral’, unlocked  
position.  This lever 
is used to lock the 
seat in either an 
upright or semi-
reclined, tilt-in-
space position.
