Natural Fusion Reserve Collection Adjustable Bed

Kingsdown Natural Fusion Reserve Adjustable Bed

Handcrafted comfort, naturally. Engineered for the way you actually sleep.

The Natural Fusion Reserve is our exclusive edition of Kingsdown's flagship Earth Tech II collection — a mattress built the way mattresses used to be built, before shortcuts. Hand-tufted. Naturally cooling. Layered with materials that breathe, contour, and last. Paired with your choice of premium adjustable base, this is the bed we'd put in our own homes.

Available exclusively at Leva Sleep.

What's inside the mattress

Every Natural Fusion Reserve is built on Kingsdown's 8" Wave coil system with Full Body Surround® edge support, then layered with materials chosen for comfort, temperature regulation, and longevity:

• FR High Loft and Joma wool fibers — naturally breathable, naturally flame-resistant, naturally temperature-regulating. No chemical fire retardants needed.
• Qualatex and gel-infused foams — pressure-relieving layers that stay cool through the night
• Natural latex comfort layer — responsive, durable, and antimicrobial by nature
• Needled cotton pad — a traditional craft layer that adds breathability and feel
• Hand-tufted construction — the old-world technique that prevents shifting, sagging, and the dreaded "body impression" that ruins cheaper mattresses years before their time
• Six reinforced handles, white chenille tape, and signature embroidery — the finishing details of a mattress built to last

Choose your comfort: Luxury Firm or Medium Plush

The Natural Fusion Reserve comes in two distinct feels, both built on the same premium foundation:

Luxury Firm (Level 2 Firm) — A supportive, traditional feel with a 13.5" profile. Ideal for back and stomach sleepers, heavier body types, or anyone who prefers sleeping on their mattress rather than in it. Built with firmer gel foam and 24 ILD latex for responsive support without sacrificing the natural-fiber comfort layers above.

Medium Plush (Level 2 Plush ET) — A cradling, contouring feel with a 15.5" Euro-top profile. Ideal for side sleepers, couples with different sleep preferences, or anyone who wants that "sinks in just right" sensation. Built with softer 14 ILD latex and an extra layer of plush gel foam for deeper pressure relief at the shoulders and hips.

Choose your adjustable base

Every Natural Fusion Reserve ships as a complete adjustable bed package. Select the base that fits how you live:

Elite 250 — The essential adjustable. Head and foot articulation, wireless remote, zero-gravity preset, and a whisper-quiet motor. Everything you need to upgrade how you sleep, read, and recover — nothing you don't.

LX Elite 500 — Upgraded comfort, smart features. Adds full-body massage with wave and pulse modes, USB charging ports, under-bed lighting, and programmable memory positions. The sweet spot in our lineup.

The Ascent — Wall-hugging design with premium support. Wall-hugger technology keeps your nightstand within reach as the base articulates. Adds lumbar support adjustment, dual massage zones, and a sleeker profile that disappears into the room.

The Evolution LX — Our flagship base. Everything in the Ascent, plus pillow-tilt head articulation, anti-snore preset, Bluetooth app control, ambient under-bed lighting, and our quietest motor system. For customers who want the most refined adjustable experience available.

Each base ships with free white-glove delivery and setup, and pairs seamlessly with the Natural Fusion Reserve mattress.
