Our luxury beds,
The Diamond Collection

The Pinnacle of Sleep, Made in England

At the heart of Marshall & Stewart lies the Diamond Collection six ultra-luxury beds, each a masterpiece of British craftsmanship. Named after the world’s most precious diamonds, every model offers a unique balance of comfort, support, and artistry.

These are not simply mattresses they are complete sleep systems, meticulously handmade using the finest natural materials to transform the way you rest.

The Diamond Collection explained

“The Diamond Collection is the culmination of everything I’ve learned about sleep over decades in the bed industry. Each model represents a different balance of support and comfort, but they all share one goal: to show you what true restorative sleep really feels like.” - Brent Cooper, Founder

Your life-changing sleep solution consists of three essential elements:

Six Bases / Divans

The foundation is everything. Place even the finest mattress on the wrong base or worse, a slatted frame and its potential is compromised. With decades of expertise and thousands of client consultations, we know the base affects the true feel of the bed. That’s why our Diamond Collection offers six carefully engineered divans, each crafted to bring out the very best in its paired mattress.

Three Mattress Systems

The mattress accounts for around 70% of your sleep experience. At the core of each lies the finest spring engineering available anywhere in the world, surrounded by layers of natural horsehair, wool, cotton, and, where required, cashmere. These fibres regulate temperature, wick away moisture, and create that elusive sensation of floating night after night.

One Deluxe Topper

The topper is the finishing touch the icing on the cake. Crafted from loose wool blended with cashmere over a core of hand-teased horsetail, it adds a final layer of indulgence. As one client described, the effect is a “sensation of floating absolute luxury.”

Together, these three elements create a complete sleep system endlessly configurable, uniquely yours, and built to outlast generations.

Koh-I-Noor

The Crown Jewel of Marshall & Stewart

Our flagship bed, where no expense is spared. The Koh-i-Noor mattress features a 3,000-spring system for unparalleled depth of comfort, paired with the legendary hand-lashed divan base whose star-formation hourglass springs are built to last a century. A masterpiece that easily rivals the £500,000 Hästens Vividus despite being 1/10th of the price.

The Cullinan

Built around a 3,000-spring mattress and a dual-layer divan with both Bonnell and pocket springs, the Cullinan delivers exquisite depth of support and lasting resilience. Designed to surpass Hästens’ celebrated 2000T.
