I would like to order a new cover and really just can't get the measurements right because it's an octagon. So i want to look up my vita spa dx series and need to know what those original measurements are so i get the right size. Where do i do that? NOTE: It is not in the owners manual for some reason and i need to know if all the dx series are the same exact size because it dosn't state which one i have , the 10, 15 or 30.

If it's a true octagon, all 8 sides the same length, ALL you need is the measurement across the middle, from one side to the other (the only reason some ask for the length of each side is to be SURE it's actually a TRUE octagon, and not a square with cut corners).

I screwed up on that. It is a four sided lounger with the angled corners. The guy at Vita spa thinks it might be 86x78 but not sure. i want to make sure i order the correct size and don't think a tape measure is the correct accuracy. So it's not an octagon! LOL
