Supportive, but too warm
I adore our Purple Mattress. The seat cushion, though, gets way too warm for me to sit on all day, even though it feels really comfortable and supportive.  I have a mesh chair, so it shouldn't be due to the chair. Maybe it's the kind of cover on the cushion, because our mattress stays really cool. I use the cover that came with the seat cushion. By noon each day, I need to take it off the chair. I just get too warm.
