Very happy with these outdoor chair cushions - they have really brightened up our patio area, looking very smart.  We have had several flash floods and showers and the cushions definitely soak through, however they are extremely quick to dry for the most part; the seam/area closest to the back of the chair holds water for a bit longer, but we simply rotate the cushion for a couple of hours to dry it out.  I was initially apprehensive about the thickness as I was replacing 3+" cushions, however for our chairs, which have some suspension, these provide plenty of cushion and look a lot smarter than the super thick pads we replaced.  Recommend!
