A direct marketer and a mattress industry veteran.

Leesa Sleep was founded in 2014 in Virginia Beach, Virginia, by David Wolfe and Jamie Diamonstein, according to English Wikipedia; Diamonstein confirmed in 2023 that he and Wolfe had started the company. The first mattress went on sale in January 2015, Fortune reported that July, when the company was already selling in the United States and the United Kingdom.

The two founders brought different trades to the business. Wolfe, the chief executive, had worked in direct marketing since 1987, and Diamonstein had spent more than twenty years at the mattress manufacturer Paramount Sleep, Fortune said. Its investor that year, TitleCard Capital, told the magazine it saw Leesa not as a mattress company but as “a technology disruption of a mature industry,” and that the pairing of a marketing executive with a mattress-industry expert had drawn it in. The writer, Erin Griffith, placed Leesa among a wave of well-funded online mattress start-ups and noted that its best-funded rival, Casper, was outspending it on marketing. Diamonstein later became Leesa’s chief product officer, a company release of 2018 said.

Griffith also set out how close the early products were. Leesa’s mattress, like Casper’s, used three layers, with a firm foam base and memory foam on top; the two companies had taken different approaches to airflow and coolness, she wrote, “and their mattress covers have different designs.” Among the other new online sellers she named were Tuft & Needle, Loom & Leaf and the British start-up Eve.

From the start Leesa presented itself as more than a mattress seller. Fortune reported in 2015 that Leesa gave one mattress to charity for every ten it sold. Under this One-Ten programme, the company said in 2018, it donates mattresses to nonprofits serving people seeking refuge from homelessness, domestic risk and human trafficking; in a 2018 release it said it had been certified as a B Corp in 2016. When 3Z Brands bought the company in 2023, Bedding News Now reported that Leesa was still donating mattresses through partnerships with shelters and nonprofit organisations across the United States.

From online-only to a furniture-store partner.

Leesa began as an online-only seller and later added physical retail through partnerships, English Wikipedia says. Citing Retail Dive, Wikipedia says West Elm made Leesa its exclusive in-store mattress partner in 2016, taking the place Casper had held, and, citing TechCrunch, that Leesa was later sold online by Pottery Barn, another Williams-Sonoma brand.

In its May 2018 release the company said the original Leesa mattress was on display in West Elm shops and that its Sapira, a hybrid combining foam with pocket-spring coils, had joined it there. The same release described Leesa as offering American-made mattresses delivered to customers’ doors, and listed pillows, sheets, blankets and foundations among its products, with a Hybrid Pillow introduced that February. It also said Leesa offered a 100-night trial with free shipping and returns.

The release also recorded who was around the table: the company had added John Replogle, formerly chief executive of Seventh Generation, and Beth Kaplan, formerly of Rent the Runway, to its board. The same release said that from its start Leesa had measured its success not only by the bottom line but by its overall social impact.

Online mattress brands and their owners.

The seven brands in this group are all mattress names: Silentnight, Relyon, Eve, Layla, Helix, Leesa and Dunlopillo. Mattress brands in general sit at many different points in the trade, from long-established factory names sold through bed shops and department stores to younger companies that began by selling online and delivering a mattress rolled up in a box, and a single name can change hands more than once while the product on the shop floor looks much the same.

A mattress brand’s identity is usually carried less by the product itself, which is mostly hidden under a sheet, than by a name, a label stitched to the side, the box it arrives in and the advertising around it. The company behind that name may have been sold, gone through administration, seen its name pass to different owners in different countries or moved its making elsewhere. That makes the questions behind each name worth asking plainly: who started it, who owns it now, and where its mattresses are actually made.

Each guide separates what independent sources record from what the company says about itself — its founding story, its owners over time, where its mattresses are made and how its look has changed — and marks plainly what rests only on the company’s own word.

Part of 3Z Brands since March 2023.

On 15 March 2023, Bedding News Now reported, 3Z Brands — the group formed when Helix Sleep and Brooklyn Bedding combined in 2021 in partnership with Cerberus Capital Management — acquired Leesa. It was 3Z’s third acquisition in a year, after Bear Mattress in July 2022 and Nolah Sleep in February 2023. Leesa’s chief executive at the time, Michael Akrop, said joining 3Z’s platform would speed up Leesa’s ability to deliver on its mission, calling 3Z a company similarly centred on quality sleep products, value and innovation; Diamonstein said that he and Wolfe had set out to simplify mattress buying, create fresh product designs with new materials and find a way to make a social impact. John Merwin, 3Z’s chief executive, described Leesa as built on delivering better sleep for customers and creating a positive impact in communities, and pointed to its design expertise. 3Z said Leesa would continue to operate under its own brand name alongside Helix, Brooklyn Bedding, Birch, Bear and Nolah.

Production now sits with the new owner. English Wikipedia says Leesa’s manufacturing was consolidated at 3Z’s factory in Glendale, Arizona; in a release dated 7 October 2026, 3Z called that plant its main facility and said it had just completed an expansion there. English Wikipedia gives Leesa’s headquarters as Virginia Beach.

For a design guide, Leesa shows how a direct-to-consumer brand can make a cause part of its identity from the first year, and how a shop partnership can carry an online name into physical rooms. Compare Helix Sleep, its stablemate inside 3Z Brands, and Casper, the rival Fortune measured Leesa against in 2015. For this guide we use a harbour teal with coral and a shell white with a serif, an unofficial interpretation; no product or logo is reproduced.
