Moroccan rugs on wood, stone and concrete: the floor decides
Which vintage Moroccan rug suits oak boards, polished concrete or terracotta tiles, and what the right rug pad does to keep the floor and the wool safe.
The boards were sanded last spring and oiled twice, and now they glow the colour of honey in the late afternoon. Someone carries a rolled rug into the room, kneels, gives it a push, and the wool runs out across the oak. Before anyone looks at the pattern, the floor has already had its say.
The short answer is this. Warm wood likes a rug with some contrast: a pale Beni Ourain on dark boards, a deep red or plum Middle Atlas piece on pale oak. Cool, hard floors such as polished concrete and stone want thick pile, because there the rug is doing a job as well as looking good. Terracotta and tiles take a flatweave happily and a strong colour even better. And under all of them, a rug pad of felt and natural rubber, never plastic.
Start with wood, the floor most rugs end up on. Oak and walnut are already warm and already patterned with grain, so a rug in the same honey tones disappears into them. Contrast does the work instead. Cream wool with a thin dark lattice sits on walnut like chalk on a slate, crisp at the edges. On pale, almost white oak, the darker rugs come into their own: madder reds, aubergine, the brown and indigo of the old Beni M'Guild pieces, which look on a light floor the way a glass of red looks on a linen cloth.
The pad matters more on wood than anywhere else. Bona, the Swedish floor-care maker, recommends felt, natural rubber or a combination of the two, and warns against PVC and plastic pads, whose plasticisers can migrate into the finish and damage it. Cheap pads can stain the boards or stick to them. Natural rubber grips without adhesives, felt gives the cushion, and together they keep a heavy wool rug from creeping and protect the varnish beneath. Grit is the other enemy. House Digest notes that small stones and hard dirt leave micro-abrasions in a wood finish, and a pad keeps the underside of the rug from grinding them in.
Size the pad a little smaller than the rug. Apartment Therapy quotes a rug specialist who trims about an inch, two and a half centimetres, off every side, so the edge of the rug tapers to the floor instead of stepping off a ledge. Match the thickness too. A deep-pile rug wants a dense pad and a thin kilim a slim one; a fat cushion under a flatweave looks odd and catches toes.
Polished concrete is the opposite case. It is beautiful, grey, cool to the eye and cold underfoot in winter, and every footstep and chair leg rings across it. Here the deep, shaggy pile of a vintage Beni Ourain earns its keep. Wool insulates and softens, and the Designing Buildings Wiki lists improved acoustics in hard-floored rooms among a wool rug's practical uses. Lay a big cream rug on concrete and the room goes quiet, the way a house goes quiet after snow. Keep the rug generous, so the sofa and chairs sit on it, and let the grey show as a wide margin around it.
Stone floors, marble and travertine, behave much the same: cold, echoing, pale. A thick pile does the same work, and a rug with some colour in it keeps a stone room from feeling like a hotel lobby.
Terracotta tiles are warm already, rust and peach and dusty pink, and they can take more colour than any other floor. A Boujad in pinks and oranges sits on terracotta like it grew there. A black-and-cream flatweave cuts through the warmth and sharpens it. Tiles are hard and slick, so a thin rubber-and-felt pad keeps a kilim from sliding when someone walks in fast from the garden.
Whatever the floor, give the room a minute after the rug goes down. Walk across it barefoot. Pull a chair out. Watch where the evening light lands. A rug that is right for the floor stops being noticed as a rug and starts being noticed as the room.
The gallery lists every rug with its pile and its size in centimetres, and the deep cream Beni Ourain pieces and the darker Middle Atlas wool are the ones to look at for each kind of floor.
