Very good classic rug. Its 12 mm pile makes it suitable for winter or all seasons. It reduces noise if you have small children who stomp on the floor. It protects you if you fall. It does not curl up at the edges so you are not at risk of tripping. Its knots, which are visible from underneath, are nothing like carpets that have non-slip rubber or latex underneath, which in a few years wears out, tears from folding, and leaves plastic dust. There are also classic rugs without knots, with latex. This classic rug is heavy and with furniture on top it stays in place even though it does not have latex underneath.
