VEVOR Camping Folding Chair for Adults, Portable Heavy Duty Outdoor Quad Lumbar Back Padded Arm Chairs with Side Pockets, Cup Holder and Cooler Bag for Beach, Lawn, Picnic, Fishing, Backpacking, Black

There are straps on the bags.

This cup holder can hold a 40oz Stanley beverage.

According to the product description, it is machine washable. Customers agree that it is easy to clean, with some noting its durable construction.

I did not find any information about replacement parts in the product description or customer reviews.

While customer reviews generally don't mention the armrests and cup holder specifically, they do consistently praise the chair's durability overall. Many note that it's sturdy and well-made.
