Dutch Design entered the industry with grand ambitions: to build not one but 10 “wellness-first” superyachts called Sea Rovers. Construction on the first 140-footer began in October 2025, with the Amsterdam-based firm now revealing more design details as the targeted April 2028 delivery edges closer.

The inaugural Sea Rover and the nine that are set to follow will all be fitted with mattresses by Savoir Beds, according to an announcement shared on Tuesday. The storied British brand began exclusively handcrafting bespoke beds for the Savoy hotel in 1905, but today has more than 13 showrooms worldwide and two workshops. The luxurious, sometimes seven-figure pieces are still made entirely by hand, with master artisans spending between 30 and 120 hours on each.

Unsurprisingly, Savoir has established a strong presence in the marine industry. Eight out of 10 of the largest superyachts currently in operation are adorned with Savoir beds or mattresses, according to the team. That prevalence is part of what attracted Dutch Design founder Scott Blum and designer Bernd Weel to the brand. The duo also recognized that quality sleep is integral to well-being, making a Savoir a must on the new Sea Rovers.

As each mattress is crafted using only natural materials such as horsetail, wool, cashmere, and cotton, seafarers can expect cloud-like comfort, responsive, bouncy support, breathability, and temperature regulation.

“We have long been the bed of choice for discerning owners who expect the same uncompromising quality at sea as they do at home,” Alistair Hughes, Savoir co-owner and company director, said in a statement. “Dutch Design’s ambition to build the world’s only wellness-first yacht speaks directly to that mindset, and we are proud to be part of bringing that vision to life.”

A good night’s sleep isn’t all one will get on the Sea Rover. The 140-footer will feature a full-scale spa with hot and cold plunges, a steam room, sauna, light therapy, and a massage table, along with a full-size custom-designed gym by Polish brand PENT and deck space for padel, pickleball, or basketball. It will also be decked out with all the regular superyacht features, including a full-beam primary suite and four guest cabins that can sleep up to 12 guests, an open-plan social area with a salon, dining area, and kitchen, plus multiple outdoor terraces, a sundeck with a pool, and a beach club. In terms of decor, performance-driven fabrics by Loro Piana will grace the exterior, while custom carpets with leather detailing by Moore & Giles will run throughout.

Dutch Design says the hull of the first unit was recently turned, marking a major advancement in the build. “With the first build well underway, our team feels more inspired than ever to deliver a vessel unlike anything else on the market,” adds Blum. “Sea Rover represents the evolution of yachting in every sense; once complete, it will introduce a new standard for what it means to live well at sea.”
