Raz is no slouch when it comes to fit
For many, an 18”-wide chair is too wide for proper postural support but, for over-toilet use, this is the minimum frame width. The appropriate solution for supporting slimmer bodies will depend on the needs of the individual. The simplest solution is to add lateral supports, mounted to the back canes in order to support the upper body. If additional support is required, thigh supports and adductors can be specified. The disadvantage to merely adding lateral pads is that the armrest will likely be positioned too far from midline. To bring the arms in, the back frame can be specified narrower than 18”. For example, a 15”-wide back frame would bring the arms 1.5” closer to midline on each side, reducing the width between the arm pads by 3”. The seat width would remain 18” since there is no advantage to narrowing it if the base frame needs to be 18” wide for over-toilet use.
