Theres chairs are terrible!  They are making a complete mess of my patio stones. They rusted after inly one week. Wayfair gave me 30 off the first week. At thisnpoint inorefer to return thrm for a complete refund as they have permanently stained my patio stones!  Anytime they rock or i have to move them, rust comes pouring out. 
Save yourself and your patio the trouble!
