Donald Fowler, the buyer at Nest, an upscale furniture and accessories store in Dallas, never envisioned offering fitness equipment alongside $498 Lazy Susans made from recycled wine barrels and $28,000 crystal foosball tables with 24-karat gold handles. As a runner, Mr. Fowler understood the fitness world’s yen for cheap, utilitarian props like the foam roller — the often grimy-looking logs used to massage tight muscles and connective tissue — but they were to be left at the gym. “Those big black wormy things,” Mr. Fowler said with obvious distaste, “are not something you’d want lying around your living room.”

But he recently found a roller that changed his mind: one that looks like an overengineered bath mat wrapped around a rolling pin, a nubby silicone confection he prefers to describe as “well designed, upbeat, almost 1960s mod.” Instead of the typical factory-made extruded foam, the RolPal, as it’s called, is made by hand in — wait for it — Brooklyn. Price: $365.

“Most everybody now has some sort of fitness regimen that they either cling to or aspire to,” Mr. Fowler said. “There’s a great opportunity for luxury that makes sense to be brought into that arena.”

Amazon offers more than 1,000 kinds of foam rollers for self-massage in various colors and densities, from swimming-pool-noodle gentle to digging-in-an-elbow painful. Most cost less than $30. But exclusive gyms, hotels and 1-percenters are snapping up the RolPal, which can be made just six at a time over two to three days in Sunset Park. The pop star Shakira has one with her name laser-etched into it. At E, Equinox’s $26,000-per-year club at Columbus Circle, which is entered by a retina scan, there are seven on the floor for its 50 members.
