Graceful Spiral Design

Sienna's signature spiral cutout on top transforms this aromatherapy diffuser into an elegant sculptural piece. The flowing, organic pattern evokes natural movement – like water ripples or wind patterns – creating a sense of harmony and flow in your space. The smooth, rounded shape with rich dark wood grain brings an earthy, grounding presence with sophisticated depth that complements contemporary, modern, and natural interior styles.

Mesmerising Light and Mist Display

Watch as the LED lights illuminate through the spiral cutout, creating a hypnotic, flowing light display that promotes relaxation and mindfulness. The gentle mist rises through the center, swirling upward in a calming visual that enhances your aromatherapy experience. This oil diffuser doesn't just fragrance your home – it creates a focal point of tranquility with its soothing spiral light patterns.

Large Capacity, Compact Profile

Sienna combines a generous 500ml water capacity with a sleek, low-profile design at just 11.5cm tall. This space-efficient aromatherapy diffuser delivers up to 10 hours of continuous fragrance while the curved, organic shape takes up minimal space – perfect for coffee tables, bedside tables, desks, or shelves. The wide, stable base ensures safe operation while the elegant proportions make it a beautiful addition to any surface.

Organic Shape for Natural Harmony

The smooth, flowing curves of Sienna's design create a sense of natural balance and harmony in your space. Unlike angular or geometric diffusers, the organic rounded shape feels soft and welcoming – perfect for creating calming, restorative atmospheres in bedrooms, meditation spaces, or anywhere you want to promote relaxation and wellbeing. The earthy aesthetic brings a touch of nature indoors.

Advanced Ultrasonic Technology

Our ultrasonic oil diffusers use water vibrations to break down essential oils into a fine mist, preserving their therapeutic properties without heat. Unlike traditional heat-based diffusers, this technology maintains the full benefits of your oils while safely and quietly filling your space with beautiful fragrance.

Aromatherapy Benefits

Use with our 100% pure essential oils for therapeutic benefits, or choose from our premium fragrance oils for long-lasting home fragrance. Perfect for relaxation, focus, sleep support, or simply creating your ideal atmosphere.
