The ARENA mattress from Senttix offers two unique firmness levels in a single product: a softer feel for winter and a firmer one for summer. At the heart of its design is a reversible, zip-off topper that can be easily detached and flipped to suit your comfort needs. One side, made with cotton and a cool thread, provides a fresher sensation, while the other, a viscose fabric, offers more warmth.

This mattress features a Multispring® core of 158 robust, durable pocket springs. Each spring acts independently, providing firm and adaptable support, reducing motion transfer, and enhancing internal breathability and hygiene. The topper’s interior is made with Blue Moon Foam, offering elastic softness and high absorption and ventilation thanks to its hydrophilic structure. The mattress is also crafted with 100% natural viscose fabric, which is soft, breathable, and ideal for sensitive skin, combining comfort and sustainability. Organic cotton, a highly breathable and hydrophilic vegetable fibre, helps to draw away excess moisture, while natural Merino wool acts as an excellent thermal insulator, regulating body temperature to prevent heat variations.
