Sof•Matt® Low Air Loss Mattress System
Operator's/Service Manual
INTRODUCTION
Gaymar Sof•Matt Low Air Loss Mattress Systems are designed to aid in the
prevention and treatment of pressure ulcers. The Sof•Matt Low Air Loss Mattress
System (fig. 1) has an internal air pump which maintains adequate pressure in its
upper and lower cells.
Please read and understand the precautions and instructions within this manual
before attempting to use the mattress system. Carefully follow the instructions
included with each mattress. In addition, we recommend that you request
in-service training from your Gaymar representative.
INTRODUCTION
Figure 1—Sof•Matt Mattress System
PREPARING THE BED
The mattress is designed for use on bed frames which provide firm, solid
support. Use otherwise may cause the mattress to be ineffective.
NOTE: • When the mattress is used on a link-spring bed frame, it may
cause the RSM mattress to sag. Additional support can be
provided by using three appropriately sized support boards. The
RSM mattress contains straps inside the bottom of its cover to
accommodate these boards and hold them in place. See figure 2.
• Support boards (Gaymar P/N 10623-000) are available from
your dealer. Boards may also be made as follows: Use 1/2" thick
interior grade plywood board, good both sides. Cut each board
to 33-1/2 inches (85 cm) long by 9 inches (23 cm) wide. Radius
all corners. Sand all surfaces and edges smooth. Make sure all
edges are rounded and smoothed to prevent wood slivers from
causing punctures, which are not covered by warranty.

OPERATING
INSTRUCTIONS
NOTE: This product is not known to be susceptible to interference from
outside sources in its normal environment, non does it produce radiated
or line conducted emission that will interfere with other equipment in its
vicinity.
1. Place the Sof•Matt
at the proper end of the bed, facing up (fig. 1, p. 3).
2. Plug the power cord into a polarized electrical outlet. The mattress will
immediately begin to inflate. The power cord is the only means to
disconnect this product from the supply (MAINS).
3. Position the Firmness Control (located behind the control panel flap) initially
as shown in figure 3.

Figure 3—Firmness Control
4. The patient may be placed on the mattress after 45 minutes. The heel
section will completely inflate within 90 minutes. For rapid inflation, insert
a portable inflator (e.g., Gaymar model SC505) into the CPR valve and
inflate for one minute. Replace the CPR plug quickly to prevent air from
escaping.
5. Apply linens, leaving the red CPR strap exposed.
SECURING LINENS (OPTIONAL)
To secure linens to the Sof•Matt Mattress, thread the four corners
through the D rings attached to the mattress (fig. 4). To ensure proper
therapy, do not pull linens taut. The linens should remain loose and wrinkly
on surface of mattress.

6. Place the patient on the mattress. If necessary, the Firmness Control setting
may now be adjusted for patient comfort.
NOTE: When elevating the head of the bed above 30°,
the Firmness Control setting may need to be increased.
OPERATING INSTRUCTIONS
MAINTAINING
PATIENT COMFORT
AND PROTECTION
1. If the patient appears to be bottomed when the head of the bed has been
raised to a sitting position (30° or more above horizontal), adjust the
firmness as described in step 6, page 4. When the bed is returned to a flat
sleeping position (0°), adjust as necessary for patient comfort.

Too Firm
Figure 5—Visual Firmness Check
2. To determine if the Sof•Matt Mattress is functioning properly, visually
check twice each day that the mattress is correctly inflated (fig. 5).
Turn the pressure control knob clockwise to increase firmness.
If the inflation is still incorrect at the maximum setting, remove from
service and contact your dealer.
3. To provide greater comfort, follow the procedure in step 6, page 4.
Check patient after changing setting to confirm that the mattress surface
is correctly inflated.
Some medical conditions may not respond to therapy of this type.

DEFLATING THE
MATTRESS
REINFLATING THE
MATTRESS
When power is removed from the mattress, therapy will be continued;
however, the height of the mattress will gradually begin to decrease.
To maintain therapy, power should be restored within 4 hours.
When transporting, unplug the power cord and bundle it on top of the
mattress to keep it from underfoot.
The lower cell will maintain internal cell pressure for approximately four hours.
The upper cell will partially deflate and the foot end will completely deflate.
The Sof•Matt Mattress can be deflated
for storage by pulling firmly on the red
CPR strap.
To reinflate, make certain to reinstall the CPR pin below the flap and to
resecure the retaining snap. Plug the system into a polarized electrical outlet.
The mattress will automatically inflate in approximately 90 minutes.
For rapid inflation, a portable inflator can be used by inserting it into the CPR
valve.

CLEANING AND CARE
CLEANING AND CARE
1. Unplug the power cord from the electrical outlet.
2. To clean, use soap and water and a clean cloth to wipe down the power
cord and mattress. Do not use abrasive cleaners. Wipe dry with a clean
cloth. Do not autoclave.
NOTE: Blood and other body fluids must be thoroughly cleaned
from all surfaces before applying the disinfectant.
3. Apply an FDA approved disinfectant or 10% chlorinated bleach solution
(chlorinated bleach with 5.25% sodium hypochlorite) to the external
surfaces of the mattress.
Allow to completely dry. The solution contact time is what makes
disinfection effective.
4. Wipe down the mattress with a clean, dry cloth to remove any excess
disinfectant.
NOTE: • Mattress cover must be dry prior to storage or
application of linens.
• Failing to remove excess disinfectant could
eventually degrade the polyurethane coating of the
mattress cover.
STORAGE AND CARE,
SOF•MATT MATTRESS
AND COVER
Individual states have established rules and regulations pertaining to
the cleaning and sterilization of mattresses that are intended to be
resold, rented, or otherwise transferred from one user to another.
Some states prohibit reselling mattresses and require them to be
disposed of properly. Gaymar recommends contacting your state
bedding department to obtain information on your state's rules and
regulations if reusing, renting, or transferring mattresses.
Clean in accordance with the Cleaning and Care instructions above.
Plastic material should not be exposed to high temperature. Do not allow heat
lamps or heating pads to come close to the mattress cover. Do not autoclave.
Do not place sharp objects in contact with the mattress. Holes in the mattress
will degrade system performance.
