Amanda...what a great looking old chair. No wonder you want to save it. However, unless you plan on three inches of concrete all around, I would strongly suggest adding some rebar in several critical areas, then a layer of stucco lath before concreteing. The bamboo won't last long in all that alkalai and I'd hate to see it lost after just one season. I know it sounds like a lot of work, but it won't take that much more than you've already planned. Just try and bend and wire some 3/8 ths rebar right to the bamboo following the existing shape. If you place a length of rebar along each of the major bamboo sections and wire them together everywhere they meet, you'll have an heirloom garden piece anyone would be proud of. With rebar and lath, you can probably get by with an 3/4's to an inch of concrete on each side. Good luck and keep us posted. Oh...and you might want to add a drainhole in the seat.

Would you consider repainting the wicker chairs? I think painting them in a bright green or coral would be stunning with your colors on the house, and make them an accent The problem with the cushions is that from any distance, like the street, they won't really show - the color and pattern will be mostly flat on the chair. Your new colors on the house sound very pretty!

Do a search on wicker motion chair and see if that's what you are looking for. Here's one I found... It's a Smith & Hawken from Target. Not sure if it rotates. Here is a link that might be useful: Target

Make sure and wear a full mask and eye coverage and long sleeves. Get the most expensive mask at Lowes with filters. I have used the spray on my wicker and it works great. Will hold well if the surface is clean and intact. There is no protection from just being outside when you spray paint so don't be fooled. If you can smell the odor of the paint then you are breathing in the particles..think paint covered lungs !! I preach on this all the time on the forums and about 50% of the folks listen. It is worth the price of the protective equipment . You really got a great deal !! c
