The many powerful features of the Freedom Bed™ have been designed with versatility and user friendliness in mind. These features have been designed to provide the ultimate in comfort and flexibility so that the bed-user or their caregiver can adjust the bed to meet their own individual needs. All mechanisms have been designed to operate as quietly as possible so that the bed-user is not woken up during their operation and particularly not during the night.

Lateral Rotation - Manual or Automatic Operation

The Freedom Bed™ has been designed so that the adjustable features of the lateral rotation system, that is dwell time and angle of rotation, can be set both manually or automatically through the bed’s user-friendly control systems. This allows the bed-user to set the bed to a customized turning schedule.

Angle of Rotation

The lateral rotation system provides for the user to be smoothly and quietly turned through a 60° range of rotation along the spinal axis. Turning from the horizontal position to up to 30° left and 30° right provides pressure relief and beneficial kinetic therapy. Rotation can be programmed to stop at any position to meet the specific comfort and positioning requirements of the user. A digital screen on the main control panel provides a read-out of the angle settings.

Dwell Time

The variable dwell time feature allows the bed user to determine how long they wish to stay at any of the three dwell positions (left, right and horizontal). Each position has an individual setting and can be set to the exact minute – between one minute and four hours per position.

Air-powered torso and leg raising systems

ProBed has developed a unique low air pressure torso and leg elevating system that provides an extraordinary level of comfort and versatility. The system works through the inflation of air cushions under the mattress that allows the mattress to conform to the bed user’s shape and provides a complete range of ergonomic positions.

The torso system can effortlessly raise the bed user from anywhere between horizontal and 70°. This is an ideal position for eating, watching TV or reading. It also assists with patient care and wheelchair transfer. The torso raising position is also beneficial for tube fed bed users since the bed user can still be rotated with the torso raised up to 30°. A higher elevation angle can be achieved by combining head elevation with Reverse Trendelenburg.

The leg raising system is ideal for bed users that obtain pain relief with their legs in an elevated position. The air pressure system for the legs has been designed so that the heels are supported in a low-pressure position when the cushion is inflated.

Powered Hi-Lo Elevation System

The powered Hi-Lo Elevation system allows the bed to be raised to an upper height of 34 inches or to a lower height of 22 inches when measured at the top of the mattress. The lower height supports transfer to and from a wheelchair and the upper height makes it easier to provide personal care to the bed-user.

Powered Trendelenburg/Reverse Trendelenburg Mechanism

The powered Trendelenburg/Reverse Trendelenburg systems will tilt the bed by up to 10° in either the head-up or head-down direction. The head-down (Trendelenburg) position can be used for postural drainage for bed-users that have respiratory difficulties, whereas the head-up reverse Trendelenburg) position provides relief to bed-users with gastro-esophageal reflux, among numerous other things.

Safety Features

The bed user and caregiver’s safety have been very much in the forefront of the design of the Freedom Beds. A number of safety features have been built into the design. They are:

  • 12 Volt DC power supply with on board charger and battery power to prevent the risk of shock and loss of operation as a result of power failures
  • Movement sensors and “lock-out” capability to ensure safe positioning.
  • For example the bed cannot be rotated if the head-raising system has elevated the bed-user more than 20° from the horizontal position
  • A unique dynamic side-rail system that moves with the bed as it rotates.
  • This design prevents any pinch or fall hazards to the patient.
  • A stable transfer surface and height adjustment for movement in and out of wheelchairs and lifts
  • Single touch buttons to position the bed user for CPR
  • A single touch override button for bed-users capable of controlling their own positioning

Quality Construction

All components are of the highest quality. All moving parts use stainless steel pins housed in composite mounts that eliminate the need for scheduled maintenance. All fasteners are stainless steel. The bed frame utilizes strong lightweight aluminum and steel sections for long-term structural integrity. All finishes are a baked-on powder coat finish for durability and ease of cleaning.

The headboard and footboard are made of wood for aesthetic purposes and all drive components and mechanisms are totally enclosed in the headboard and footboard to provide excellent soundproofing and to ensure that there is no risk to the user or caregiver. The air-powered torso and leg raising systems are constructed from welded, clinical grade fabric and have undergone exhaustive testing and peer review.

Power Systems

The Freedom Bed™ is powered by a low voltage system (12 V DC) that eliminates the risk of shock to the bed user or their caregiver. The bed’s built-in batteries can power the bed for a number of days to continue repositioning in the event of power failures (the number of days varies depending on the turning schedule). A 12 V “smart charger” system ensures that the batteries are always fully charged. The Freedom Bed™ has CSA, UL544, and FCC approvals for its electrical systems.

Voice Control Option

Low Operating Costs

The operating costs of the Freedom Bed™ are significantly lower than other options since regular maintenance or replacement of consumables is not required. In addition the use of DC power systems reduces power costs to about 3 to 5 cents per day or an economical $1.00 to $1.50 per month.


The high quality construction of the Freedom beds allow us to offer the following warranty:

Mechanical and Electrical Components:

3 years


2 years

Warranty does not apply to woodwork, batteries, fuses or to any component which, in ProBed’s opinion, has been misused, altered, neglected or damaged by accident, presence of abnormal conditions of operation or handling.

A study in 1987 that was published in the journal “Stroke” showed that the risk of infection for stroke patients placed on normal hospital beds was 2.9 times greater when compared with a study group of patients placed on rotating beds.


medical conditions

The torso raising position is also beneficial for tube fed bed users since the bed user can still be rotated with the torso raised up to 30°. A higher elevation angle can be achieved by combining head elevation with Reverse Trendelenburg. Severe respiratory ailments such as chronic obstructive pulmonary disease. Spinal cord injuries causing paraplegia and quadriplegia. Muscular dystrophy and multiple sclerosis.


Bed Turning, Pressure Ulcers, Decubitus Ulcers, Bedsores

The traditional way to avoid the formation of bedsores is for a family member, caregiver or institutional employee to regularly turn and stabilize the patient in a new position to relieve tissue compression and re-establish blood flow. It is estimated that approximately 1.2 million people are suffering from bedsores at any one time in the United States alone and almost 70% of sufferers are over 65.

As the bed smoothly and quietly rotates to one side the outer section of the three-part platform on the lower side turns up to form a “wing” which supports the body along its entire length from the ankle to the shoulder. The Freedom Bed™ is a unique, computer-controlled, therapy system that manually or automatically turns the bed-user to different stable sleeping positions without the aid of caregivers or institutional staff.
