Ordered both the 43.75” and 66” length cushion, height 3”. One is a 3” foam cushion in a 2” cover, the 43.75 measures exactly as states. The 3”x 66” x18” actually measures 2” x64” x 18”.  Ordered a replacement which came late and once again incorrect dimensions. Wayfair called the warehouse who are aware of the issue however do not have a the cushion that matches the description listed  on website And have no solution at this time
