You can find standard weight double folding chairs in various sporting goods stores around the country including Sportsman’s Warehouse, Dick’s Sporting Goods, and Sports Authority. You can also purchase them online from Amazon.com and various other retailers for $26.99 to $34.99. Some of these chairs do not even have an arm rest in between and should be called love seats instead. These lower price point double folding chairs are usually made of 400D nylon and come with their own carry bag with strap.
A camping company in Canada, mosquitocontrol.ca, has what they call a Love Seat with Table that is actually two chairs attached together with a table in between that has various storage options for your camping or sporting event needs. It retails for $64.99 has a powder coated steel frame to prevent rust and has arm supports with mesh cup holders and folds up into a package slightly larger than the single folding chairs you find everywhere.
Firepies.com offers a better alternative to the item from Mosquito Control. Their double folding chair also has a table in between, but it integrates a cooler into the table top and still has storage pockets for other items. It includes extra padding in the seat and back and is rated to 225 pounds per seat or 450 pounds total. The high strength steel frame combined with a strong nylon material attached with reinforced grommets and seams make this a durable seat you can enjoy for years in the outdoors. You can get this model with the cooler for only five dollars more than the item at Mosquito Control.
