The seat on this diwan is a loose cushion, and it is built so that it can be turned four ways without ever looking different.
A fixed seat wears in one place. Whoever uses the diwan sits in the same spot, and after a few years that spot is visibly softer and slightly darker than the rest. There is nothing to be done about it, because the seat cannot move.
A loose cushion can be rotated end for end and flipped over, which spreads that wear across four positions instead of one. But it only works if every one of those four presentations looks the same - and on a patterned cloth that is not automatic. If the pattern is centred on the top face only, flipping it reveals an uncentred underside; if the two ends differ, turning it end for end changes the look.
So both faces of this cushion are cut with the pattern centred, from the same part of the repeat, and the cushion is made symmetrical end to end - piping, seams and fill all balanced.
Turn it however you like. It looks the same, and it wears four times as slowly.
