Birthing Bed | Affinity® 4

Supplier: Hill-Rom Australia

In labor and delivery, every second counts. You must be able to respond quickly and easily, especially in an emergency. The Affinity® 4 birthing bed delivers on the promise of a safe birthing bed that functions in the busiest environment with ease.


No more hassle with a removable foot section. How do you remove it? How does it go back on? With the Affinity 4 Stow and GoTM feature, the integrated foot section simply slides under the bed for birth and back into place afterward.

Or, if you choose our ergonomically designed lift-off version, simply place the foot section on the built-in stand.

In labor and delivery, staff time is at a premium. No one can spare even a few minutes to search for equipment, look for an outlet or use complicated controls. The Affinity® 4 bed is designed to reduce the hassles you face every day.


The Stow and GoTM  foot section slides and stores under the bed–no lifting required. The foot section easily slides back into place without false latching or interference with linens.

With battery backup, you can use all the bed’s features, including changing height and position, when you’re away from an outlet, reducing the time from “decision to incision” in critical situations.

The gas-assist Trend mechanism allows head elevation to immediately lower to 8 degrees.

OneStep® siderail release provides zero transfer gap for safer and easier patient transfers.

The bed’s streamlined design, with all the equipment stored completely within the perimeter (instead of protruding out), protects you as you move quickly around your patient.

  • The foot section locks firmly and easily in position.
  • EasyGlide® calf supports swing into the correct position and lock with a single lever, staying firmly in place.
  • Trend mechanism, with improved springs and seals, makes lowering and lifting an easy, one-person job.

  • Four dual-lock casters keep the bed in place.
