• Both sisal and sea grass are great as hallway runners and foyer rugs.
• Natural fibers are not suited for kitchens or baths, but definitely consider them for dining rooms, bedrooms, home offices, and family rooms.
• They should not be used on stairs because their texture can be slippery.
• Both can be installed wall to wall. Remember that natural fibers can scratch hardwood floors, so a thin pad or latex backing is suggested.
• While they feel nice underfoot, natural fiber rugs may be uncomfortable for lounging. So, they're not the best choice for playrooms or TV rooms where you may want to stretch out on the floor. If you have small children, layer softer rugs over natural fiber ones for more color and texture.
