Okay, so the ZUCA can support 300 pounds, but what if you have to sit for a REALLY long time?  Hey, no problem - make it through those long sit-athons with the addition of a fully reversible seat cushion. (Aaahhh, that's what I'm talkin' about.)  They come in five different color combinations to coordinate with the ZUCA Sport Inserts: Black/Red, Gray/Gloss Blue, Hot Pink/Pale Pink, Turquoise/Brown, and Purple/Lilac.  Now if you want to get even MORE insanely comfortable, you could always buy two.  We promise to wake you up.
