A few helpful answers
Get to know your SitMora cushion, from finding the right fit to caring for it.
SitMora is a separate cushion that sits on top of your chair. Its contoured surface and U-shaped opening at the back give it a different shape from a flat chair pad.
It’s a simple way to add cushioning to a compatible seat without replacing your chair.
Compare the cushion’s dimensions in the product details with the usable width and depth of your chair seat. Measure the space between the armrests, if your chair has them.
Choose a seat where the cushion can lie flat without folding or hanging over the edges. Remember that adding a cushion also raises your sitting height.
Place the cushion flat on the seat with the U-shaped opening toward the chair’s backrest. The broad, closed edge faces forward.
Center the cushion on the seat, then adjust your chair height if needed so your feet can rest comfortably on the floor or a footrest.
The opening leaves a space in the cushion beneath the tailbone area when it is positioned correctly. This is the main difference between the U-shaped design and a solid, flat cushion.
How it feels will depend on your chair, sitting position, and personal preference.
Yes. You can lift the cushion off one seat and place it on another compatible chair.
Check the fit each time, especially when moving between a desk chair, dining chair, or folding chair. The cushion should rest flat and stay steady when you sit down.
Check your vehicle’s guidance on seat accessories first. A cushion changes your sitting height and may affect seat-belt fit or seat features.
While parked, make sure it does not interfere with the seat belt, controls, visibility, or access to the pedals. Only use it if it works safely with your vehicle and driving position.
Follow the care label and the instructions included with your cushion. The cover and inner cushion may require different care.
Check those instructions before machine washing, tumble drying, or soaking any part of the cushion.
