Mattress topper corner radius intersection

[Cajundanzman75]

Oliver Univ notes that the corner radius for the twin beds is 16.25".  On the diagram, it even has a dot for the intersection with which to do the radial curve. However, it does not note the measurements down and over for the intersection.  I may not have stated this clearly, but I'll bet someone out there understands my challenge and has the information. We are in the process of preparing ahead for the delivery of our Ollie and have cut the length and width of our topper. Only have radius left.  Anyone know the intersection point measurements for the radius starting point?  See file attached with radius starting point but no indication of measurements to isolate that point.

I don't know if this helps, but all you have to do is subtract the radius of 16.25" from the length and width and I think you have the measurements you are looking for.  

In other words, the radius starts 16.25" from each of the two corners where the radius cut is made.

Are you looking for the location in x/y on the mattress of that little dot for the radius?

If overall width is 29.88 and R is 16.25, then the little dot is located at an X distance of  (29.88-16.25) or 13.63 from the left side of the cushion...and since it's also at the radius the Y distance from the top of the cushion is 16.25.

Forgot to mention we bought our cover and sheet sets from AB Lifestyles who have both top and fitted bottom sheets for Oliver Mattresses in a variety of colors.

Thank you AndrewK and ctshort09.  Yes, my brain was clearly fogged.  HA!  Then I had an epiphany and thought - "Wait! this is simple geometry.  As I write this, both corners are already cut to radius. BTW, as a new owner who isn't even going to take possession until May 14, I must admit to being bummed at the rally cancellation. We have been organizing supplies and outfitting and are 95% ready to go.  Not certain if we will go on to Guntersville anyway or some other direction.  Anyway, thanks for the advice. By the time I got back to my computer it was done . . . but the fast response was appreciated. 

Cheers,  Scott Dyer

I always thought that someone actually stayed awake during that part of class 😁.

I actually just simply traced the radii with a Sharpie and one of the existing cushions that was radiused. Then cut the mattress topper foam with a sharp pair of scissors. It worked like a charm and the topper cover slipped over the 3 in.foam and assumed the shape.
