We have patio chairs and chaise lounges that we like very much.  Trouble is, they are 10 years old and the seating material (called a sling in the trade) began to wear out.  One of the seats was completely ripped.  The frames, on the other hand, were in great condition.

My wife and I went to a patio furniture store to price out a replacement set.  Chairs were $300 each and chaise lounges, $450.  The table would cost another $800.  Total price for a replacement set: $4400.  Not money we wanted to spend.  But there was another answer.

Enter Chair Care Patio, a company that custom manufactures replacement slings and webbing for your patio furniture.  For about $75 a sling (sometimes they run a promo that brings the cost down a bit) I was able to order 6 replacements for my dining chairs, in a pattern that complements the chaise lounges, which do not yet need new seating material.

It took me more than an hour to replace the webbing on my first chair, and about 30 minutes for each of the rest.  Chair Care Patio provides very clear instructions and wonderful pre- and post-purchase support, including free samples of their materials.  They only thing I would add to their instructions is to use work gloves when you are working with the slings - the material is very tough on the hands.
