I won this chair and loved the pattern and color.  A couple of years ago I changed up my bedroom color to light grey and a soft turquoise.  I decided to find a chair cover instead of recovering the chair which was costly.  My chair dimensions are all within the stated ones on the site 
( no seat depth though so I decided to chance it) but as you can see it does not fully cover the seat to the bottom. My seat depth from top to bottom is 5.5 inches, the cover itself is stretched at the chair seam with little holes appearing once we stretched it over the seat. I LOVE the color and pattern and am still happy that my desk chair matches my over room color and style now.
