Product and specification
Describe intended channel or placement, requested track and roller mechanism, massage coverage, air-cell zones, heating request if any, recline and zero-gravity positions, controller format, upholstery expectations, chair dimensions, user-fit limits and acceptable substitutions. Include what the supplier must identify as standard, optional or unavailable.
We place alternatives on separate lines instead of treating a similar feature name as equivalent. This makes changed construction, control logic or included equipment visible to the buyer.
