An armrest is something that helps you to keep your arms comfortable when you sit in a chair.
Imagine you're playing a game or watching a movie, and your arms feel like they're getting tired or sore from just hanging down at your sides. That's when an armrest can come in handy. It's like a little shelf that you can rest your arms on so they don't have to work as hard.
Armrests are usually attached to chairs or sofas, and they can be made from different materials like wood, metal, or soft padding. Some armrests even have cupholders or pockets where you can keep your snacks or remote control.
So, if you ever feel like your arms need a break from just hanging down, remember to look for an armrest!
