That is post of Japanese driver from kakaky site in thread about cracks in driver seat upholstery
Sorry for google translate, it’s not always working correctly
“My own is a Fit 3 Blemium Brown interior seat, but it cracked.
I got a free replacement, but first of all I think that it will be the same if I handle it in the same way as before because there is no countermeasure product, so I will bring my body to the seat center when riding so as not to crush the side of the seat from above Especially when getting off, I put my hand on the door lock striker in the center pillar to prevent weight from being applied to the seat side surface.
When I saw it cracked, I thought it would be nice to make it from cloth.
I was worried about whether to use HVL or HVS, but when I saw this point, I thought it would be nice to use HVS.
However, if you are conscious of countermeasures when getting on and off, it seems that getting on and off so far has put a burden on the side part of the seat, and the shorter the foot, the more the load will be applied until the foot reaches the ground and the side will crack. It was concluded that people with long legs could get off before the load was too heavy and would not crack easily.
It seems that it is necessary to take measures on how to get off rather than expecting countermeasures.”
