That sounds like the best option! If you can, get pre-sized strips. I recall it being extremely difficult to cut the wire; I could not do it at all with any snipping tool and had to resort to a grinder, which was hard to use on them because of the shape and the flex.

When sat on, did the springs curve the other way - did they bend down? If so I would consider replacing them, they should still keep their upwards arch when sat on, just flatten out some. Also if they flex quite differently, spring to spring, that's a hint that at least some of them may be wearing out. I don't know if there's a rule for the height of the arc, but they should all have the same arc, and they should all flex quite similarly when pressed on. From your description, I would guess that the middle springs are wearing out... if you don't want to replace them yet it *may* be possible to get more life out of them by swapping with the outside springs, but you'll have to make that judgement yourself.Good luck!

Utterly ridiculous :) I love it

Because I didn't know how to make the PDF print to size. You can alter it on a photocopier that has a zoom feature, or on any photo editing program. There are inch measurements marked on the pattern to show the size it should be.

That looks great! Thanks for posting a pic, it's always lovely to see someone else's work :)

It doesn't have to be at all precise. Any oval that looks reasonably like the pictures will work fine. I usually make it by folding a piece of paper in quarters then cutting a quarter oval, opening it up, and trimming until it looks about right and has about the right circumference.Post a pic when you've made yours!
