Mammoth Comfort Collection: Elevate Your Sleep Experience
Discover unparalleled comfort tailored for your health and well-being with Pronto Beds' a Mammoth Comfort Collection.
From the moment you lie down on a Mammoth mattress, you'll notice its premium high-performance fabric. Not only does this fabric feel cool to the touch, but it also actively regulates your body temperature throughout the night. This innovative design reduces night sweats by up to 50%, ensuring you stay hydrated and promoting optimal brain function. Crafted with a hypoallergenic and breathable polyester layer, made from at least 70% recycled materials, this sustainable feature encourages healthier sleep while supporting eco-friendly initiatives.
Unlike many mattresses on the market, our fabric is not overly taut, allowing you to move freely as you sleep. The state-of-the-art Pro-Bio Fabric cover provides unmatched protection against allergens, bacteria, and odours, ensuring a clean and fresh sleep environment.
Key Features of the Mammoth Mattress:
- Signature Medical-Grade Foam: At the heart of our mattress lies our unique medical-grade foam, designed with posture cells technology. These innovative cells, shaped like tear drops, open fully when you lie down, facilitating air circulation to keep you cool. With five distinct comfort zones, our mattress delivers targeted support where it matters most, alleviating pressure points and ensuring full-body support.
- Pressure-Relieving Halofoam: Our elastic viscose Halofoam offers added flexibility, allowing you to move freely and enjoy uninterrupted sleep.
Our medical-grade foam isn't just about comfort, it is backed by science. Independent studies have shown that users fall asleep 29% faster, experience a 7% increase in sleep efficiency, and enjoy 21% more restful sleep. Additionally, our foam provides 47% better pressure relief and cools 69% faster than traditional foams.
