modular carpet tiles (Heaven Sent, $14 each; flor.com), which are relatively inexpensive and durable. If a truly disastrous spill leaves a stain, you can replace the individual tile, not the whole rug.
I like the subtle pattern in this and the texture. The original pinner said these were super soft and comfy to walk on. I am worried that floor tiles will feel too sterile or too much like office carpeting in an ad agency, like the surface of a tennis ball. Again, I would need to see and feel the tiles, haven't seen a Flor swatch in at least 10 years. Surely they have come a long way in comfort and coziness
