Office workers and gamers, if your chair armrests are cracked, uncomfortable, or just ugly, these AAGUT replacement pads are the perfect upgrade! Each pad measures 4 inches wide by 10 inches long, giving you plenty of comfortable surface area for your arms and elbows. They're sold as a pair (left and right are identical), and they come with 8 screws and a handy wrench for easy installation. The mounting screw holes are 4 inches (100mm) apart, and the cut-out area for mounting is 5.9x2 inches (150x52mm) - just measure your existing armrests to make sure they'll fit before ordering. Installation is seriously simple - even if you're not particularly handy, you can probably get these installed in 10-15 minutes with the included tools. The durable materials are crack-resistant and easy to clean - just wipe them down and they look like new. The ergonomic design provides much better support than cheap original armrests, which is crucial if you spend long hours at your desk. The black color matches most office chairs and gaming chairs, and the texture has just the right amount of grip without being sticky. Whether your current armrests are worn out, you want something more comfortable, or you're just refreshing an older chair, these replacement pads make a huge difference in your daily comfort. Your elbows and forearms will thank you during those marathon work sessions or gaming marathons. The quality feels substantial - they're not flimsy or cheap-looking, and they install securely without wobbling. One of those simple upgrades that makes your workspace so much more comfortable without breaking the bank!
