Cheap laptop protector
This is what I use: a back support: they are flexible, adjustable, sturdy, and give you a firm grasp of your laptop so it’s less likely to slip from your hands as our filling your coffee cup with sugar before you sit down to study or work. I use an “Ace” brand and it works great. You have the added benefit of using the brace as a brace while you’re working long hours, and it helps you remember to maintain proper posture. Just compare these to the laptop ’sleeves’ that are sold specifically for laptops. These are far superior.
