It's important to get a desk that fits your available space, provides an adequate work surface and appeals to you aesthetically. Consider how you plan to use your desk to find the one that's right for you.
For general-purpose work, a medium-size desk with built-in storage, such as a hutch, is often a good choice. L-shaped desks can help maximize your work space if you like to spread out, while writing desks can work well if you don't need a large work surface and are good choices if space is at a premium.
If you'll be using a desktop computer, make sure to choose a computer desk with enough room for your computer and peripherals. Also make sure that there's enough space left for any non-computer work you'll need to do.
If you'll be using a laptop, you can get away with a smaller desk, such as a computer cart or a student desk. Portable laptop desks can also be good options.
At Walmart, you'll find a wide variety of desks at Every Day Low Prices.
