Description
Orthex fixed side rails for the Sophia 2, Sophia 3 and Sophia 4 adjustable bases are a black steel pair, 16.5 by 20 inches (42 by 51 cm), part 721620.
What does it do and how does it work?
- Each rail is a rigid black steel frame that stays raised beside the mattress.
- There is no hinge, release or lock, so it does not drop, fold or slide away.
- The pair fits both sides and gives a handhold for turning; each rail covers part of the side, so the foot end stays open.
Who is it for, and who should choose something else?
- It suits a Sophia base where a rail should stay in place on both sides.
- Choose the retractable pair when the rail must clear the side for transfers or bed making.
- Whether to use rails at all is for the care team to decide.
Will it fit?
- It fits the Sophia 2, Sophia 3 and Sophia 4 bases at their side-rail anchors.
- The rail is fixed to the base, so a thicker mattress leaves less rail above the sleeping surface.
- Send the base model and serial and your mattress depth; we check the pair before you order.
What does it work with, and what are its limits?
- It is made for the Sophia base, not for Drive, Invacare or Joerns hospital bed frames.
- Health Canada advises checking that the mattress is the right size and type for the frame before rails are used; a poor fit can widen the gap at the rail (Health Canada hospital bed safety).
- Rails support getting in and out; they are not a restraint.
How does it compare?
- The retractable pair is black steel too, in a 28 by 22 inch short pair or a 58 by 22 inch long pair that locks and retracts.
- The Drive half-length bed rails fit Drive frames, not a Sophia base.
Frequently asked questions
Is part 721620 one rail or a pair?
It is a pair: one fixed rail for each side of the base.
Does mattress depth change how the rail sits?
Yes. A thicker mattress leaves less of the fixed rail above the sleeping surface.
Do the rails come with the bed?
No. The base and mattress are separate, and this pair is ordered as part 721620.
