The Cooler Springs model is provided with a pocket spring casing, with five honeycomb-shaped lumbar areas. The 380 gr Cooler fabric and the Koules fabric, with which this mattress is made, is a special fabric that gives off a pleasant sensation of freshness, which helps us to rest better during the summer season, while on the lower side it has a fabric more typical of winter. It is therefore a reversible mattress, which is essential to turn over, depending on the time of year. It is also equipped with 3 cm of memory foam on both sides.
