Stone may be cold and unyielding, but it can still have comforting qualities. It feels sturdy and durable, with a presence that remains constant as everything else changes around it. In its smaller forms, as river rocks burnished into smooth rounded shapes by the forces of flowing water, stone can be extremely satisfying to hold in our hands. It’s not exactly our first choice as a material for furniture, especially when it comes to seating. But a new furniture series by Sofia Lagerkvist and Anna Lindgren of Front Design renders the pleasing shapes of river rocks in soft, cozy materials for beautiful nature-inspired sofas that are a lot comfier than they first appear.

Lagerkvist and Lindgren’s design process involved researching the therapeutic benefits of nature to determine what people find most calming and relaxing. The designers believe the allure of stone lies in its symbolism, representing “nature’s slow and boundless rhythm.” When translated into malleable materials, those same qualities can feel like the reassuring embrace of Mother Nature herself.

The designers wanted “Pebble Rubble” to transcend the functions and qualities of an ordinary seat, reminding the user to slow down and appreciate the resilience and dependability of the natural world. The shapes of the rocks call to mind the process by which all the jagged edges were polished over long periods of time by the rain and wind, perhaps cloaked by a coating of moss or a layer of fallen leaves.

Imagine we find ourselves upon a massive, mysterious slab of stone,” say Lagerkvist and Lindgren. “As if, in a time long before our own, someone gifted with superhuman strength lifted and positioned it, creating a megalithic seat. Let’s imagine that all this occurs in an unexpected location – in the entrance of a bank, the lounge of a hotel, or in the halls of a library. Lastly, let’s imagine that we are getting closer to its surface and only then becoming aware of their softness.”

“Our new system of furniture for Moroso took its forms from found shapes in nature. As children in our native Sweden, our playground was the forest, and we imagined rocks, moss, and fallen trees to be furniture and places for the body to rest and occupy. For this seating group, we 3D scanned rocks we saw on our many forest walks, and composed these organic shapes together into furniture pieces.”

Designed for Italian furniture brand Moroso, the modular cushions of the Pebble Rubble sofas come in 15 different shapes and sizes, and a range of colors including beige, gray, brown, green, lavender, and orange. Each one is available in 16 new textiles produced by Kvadrat by digitally scanning natural surfaces like moss, minerals, and snow for a realistically organic effect.

You can custom-order your preferred combination to create oversized river rock vignettes that fit your space, choosing from shapes that can act as base cushions, back support cushions, throw pillows, and stools.
