## Features

- Cooling and breathable – Mattress cover with the new Nanotex Coolest Comfort Technology is moisture-wicking and dries quickly to balance your body temperature throughout the night. The sleeping surface is treated with an embossing process usually applied to sports fabrics, making it more breathable and stylish than ordinary material and brings an advanced dynamic atmosphere to your bedroom.
- ULTRA SOFT & FLUFFY We use 120 gr/m2 thick brushed microfiber as a sleeping surface. Overfilled with 340g 5D spiral fibre. The fibre filling maintains excellent softness and resilience, making this mattress topper super fluffy. Enjoy the comfort of a luxury hotel at home.
- UNIQUE 3 ZONE DESIGN This mattress topper is ergonomically designed with three zones. The head and foot areas use a wavy design that can ensure that the edge is not deformed. The body area in the middle uses cloud-shaped quilted design to provide a larger body support area that distributes the pressure of the body and prevents sagging. It helps to naturally stretch your body for a deep and relaxed sleep.
- Deep pocket, easy to care for – quilted, stretchable (8" - 21"): The knitted skirt pocket is up to 21" deep and can be easily placed on most mattresses. The 4.1 cm wide high-quality elastic sports trim holds your bandage securely in place, and its excellent elasticity makes the bandage easy to attach and remove. It ensures the most restful and refreshing sleep. Machine wash cold, do not use bleach, tumble dry on low heat.
- SATISFACTION PROMISE - SLEEP ZONE has over 40 years of experience designing and manufacturing high quality bedding. Our products are Oeko-Tex certified. - -
