Flat Purple seat cusion
Quite an advantage when sitting for a prolonged period on hard surfaces.. Not really &#34;soft&#34; but adds a lot of comfort as your weight seems more distributed and hence the &#34;No-Pressure&#34;.  It is very portable and works on many surfaces. My wife sits on it when on a soft sofa and has significantly less lumbar pain. . I have been using 2 different types of the horse-shoe shaped chair cushions (with the sacral cutouts) for about 1 year  and find these to be amazing when sitting for long periods on a wooden chair.. but they are more rigid and do not quite distribute pressure like the purple... To be honest... I put the purple pad on the chair.... then the anatomically shaped butt cushion and together they are the ideal solution. Most comfortable sitting arrangement I have found ever.
