For a cheap and comfortable chair that works well for studying, office work, and gaming, you’ll want something that offers support but doesn’t break the bank. Look for an ergonomic chair with adjustable features like height, backrest tilt, and armrests. Here are some options that are generally recommended:

1. **AmazonBasics Mid-Back Office Chair**: It’s affordable, has good lumbar support, and is easy to assemble.

2. **Hbada Office Chair**: A budget-friendly ergonomic chair with decent back support, often praised for comfort during long hours.

3. **BestOffice Ergonomic Chair**: A highly affordable and simple chair with lumbar support and adjustable settings.

4. **Homall Gaming Chair**: While marketed as a gaming chair, it offers great comfort for office or study work as well, with a reclining feature and decent padding.

While budget-friendly, these chairs still give you comfort and support for longer sitting sessions without causing strain. You can find many of them online, and they generally offer decent quality for their price range.
