What is the material of the chair exterior? Does furniture dry quickly? We want it for a porch. Also, is there a store where we can see it near Panama Cry, Fl? I want to be sure it is comfortable. Thank you!

Seating Frame Material: Aluminum Alloy Cushion Upholstery Material: Olifen Rope A little bit of water is found but you better cover or hide them if it rains heavy or extremely hot sun. We don't have a store yet.

Can the legs be removed and replaced on the 4-Pieces Outdoor Sectional Sofa Set with Webbing Seats and Cushions in Beige? Are they screwed onto the frame?

Yes, the legss are screwed onto the frame. You can read the installation guide: https://img2.homary.com/mall/file/2022/05/07/1d007f2fb0ee45cb91bcd172a061ddf5.pdf
