The type of flooring you choose for your bedroom comes down to personal preference. Many people prefer carpet over hard-surface flooring types (such as hardwood, tile, or stone) in their bedrooms because it’s warmer and cozier. Carpeting also helps muffle sound, which may benefit those who have trouble sleeping.

On the other hand, some folks prefer the look of hardwood over carpet. People with allergies might also opt for non-carpeted flooring since carpet fibers can attract dust, dander, and other allergens.

In most cases, you do not need to put padding or underlayment under carpet tiles. Unlike traditional carpet, which requires a separate pad, carpet tiles are designed to be installed directly onto a firm subfloor like plywood, concrete, or tile. Many carpet tiles come with a built-in underlay and attach with peel-and-stick adhesive, double-sided carpet tape, or glue. For a more comfortable, cushioned feel, especially in residential settings, you can opt for padded carpet tiles that have a thicker underlay attached. While it's generally not recommended to install a separate pad, a compact underlayment might be used in some situations, though this typically requires professional installation. An acoustic underlay may also be considered in commercial spaces or multi-level homes where noise reduction is a priority.

If you’re using a carpet runner instead of a traditional carpet, pay attention to your width measurements. Instead of measuring the total width of your staircase with 2 added inches for foldover, simply measure the width you’d like the runner to cover. Runners generally come in standard sizes, so you may need to approximate what would look best in your space.

There are a couple of color options to consider when installing carpet in high-traffic areas (like entrances and stairways). Medium-toned colors and patterned carpets can work well in these parts of your home because dirt and stains can blend in easily. Dark carpets will also conceal marks and spills, but they show lint and other light-colored debris. Consider a medium brown or tan for your high-traffic areas. Either way, it’s best to avoid paler shades, like white and cream, which get dirty easily.
