Affinity 4 Stow and Go, Lift Off Foot Section
Affinity 4 Stow and Go, Lift Off Foot Section

Two Design Options Available

Stow and Go® No-lift Patient Foot Section

Convenient, stow away foot section stores under the bed, eliminating lifting and saving you valuable space in the birthing suite.

Light Weight Lift-Off Foot Section

Lightweight and easy to handle, the foot section stores on a built-in stand keeping the mattress of the floor.


EasyGlide® Calf Supports

Wider support with a strong release lever that can be actuated from any angle with one hand.


Ergonomic blue handles with integrated IV pole cradle

Posture and efficiency were taken into consideration with this option to the Affinity 4 Bed. Caregiver posture is naturally directed to a comfortable position with the angled design of these handles.

You can also transfer 2 IV poles at once without assistance because of the IV pole cradle that is built into these handles.

Integrated IV Poles

Integrated IV poles offer a permanent solution for ease of transporting fluids.

Line Managers

Optional line managers offer you the ability to maximize the organization and efficiency of your medical equipment lines.

Battery Backup

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.
