The addition of spacers is something really helpful for those in-between chair sizes.
Spacers can add and extra 2cm between the armrests 1cm either side.
Example say a smart chair 1 has a space between the armrest of 48cm but the smart chair 1 xl has 53cm. And your current chair has 48cm but is a touch snug, that’s when we could add spacers for you to make hot 50cm between the armrests
Suitable for: SC-1 , SC-1 XL , SC-2 , SC-X , SC-XL
