outdoor or interior...benches and chairs cut to fit ,frame made from treated lumber 2x6,cut pine planks for back and seat,all sanded and finished to customers like,tell me what u like and ill make it...very sturdy and made to last,all bolted...no screws...ok as for the chairs they are very sturdy and comfy,38hx26wide in the seat x37 total width so they sit really well the one in the pic is old maple stain,i have both pine and maple wood for the seats and backs keep in mind these are all solid wood and for the most the slats are  1" thick and 3 1/2" wide so they are very strong ,maple wood would cost $100.00 more but its really nice...thanks for looking.
