We were tasked with replacing the foam cushion and seat covering on a pair of kitchen chairs. Removing the existing fabric seemed simple, until I pulled a dozen staples holding the cardboard cover to the bottom of the chair and exposed the fabric stapled to the MDF plate:
That’s just part of one corner. Obviously, whoever built the chair wanted to be very very very sure the fabric didn’t come loose!
Removing the staples from one corner produced a pile:
Piling up all the staples from the other chair looked even more impressive:
I fired maybe a third as many staples into the new fabric, which seems secure enough.

Definitely not: the fabric wore out on the top surface, but the bottom wasn’t going anywhere!
I was unaware IKEA did food, though …

These chairs used plain MDF, nothing fancy … and even the cat knows better than to chew MDF!
