Flats!
Flat-weave rugs may not be the softest underfoot, but these thin, durable, low-maintenance rugs are the perfect solution for some spaces. You can find flat-weave rugs in a dizzying array of colors and patterns. Even better, flat-weave rugs often one of the most affordable options in floor coverings. Did I mention they're often reversible?
For allergy-prone people, flat-weave rugs are a great option since dust and dander won't get embedded in thick piles, like other carpets. They still visually define a seating group or space and add texture to a room - something you'll lack if you leave your floors bare.
