Is this rug really machine washable?

Yes. It is designed to be washed at home, which is the main reason to pick it over a standard area rug. A 9x12 is large, so check that your washer or a laundromat drum can take it.

Will it stay flat on hardwood or tile?

It has a non-slip backing, so it grips hard floors without a separate pad. On thick carpet or very smooth surfaces, a pad still helps.

Does the floral pattern look busy in a large room?

The multicolored floral print on beige is bold, so it works best as the focal point of a room. Pair it with solid furniture and neutral walls.

Is it soft enough for a living room?

It is a low-pile, printed rug, so expect a flat, firm surface rather than a plush one. It is comfortable for walking but adds little cushioning.

What sizes and colors does it come in?

This listing is the 9x12 in the beige multicolored floral design. Other sizes and colorways exist in the Gaomon line, so match the model name if you want a different one.
