Mattress Spring System

The 16 cm Aloy® 3.0 is our latest innovation in advanced spring systems. It takes care of the entire body, including the hips, which just like the shoulders, are a vulnerable part of the body. This mattress is composed of triple pocket springs distributed into Jensen’s Original 5 Zone System providing support for the arch of the lower back in combination with a soft shoulder zone. These triple springs soften the entire mattress surface since the inner springs only comes into contact with your body when you sink into the mattress. The secret behind our upgraded Aloy® 3.0 spring system is an extra soft shoulder zone to reduce pressure on this part of the body, particularly important for those who mostly sleep on their side.

Jensen TempSmart™ Mattress Topper Protector Jensen Store

Mattress Topper

This bed comes with our TempSmart™ Topper. The TempSmart™ Topper is a mattress topper with a thermo-regulating cover which helps balance body temperature changes that can interrupt your sleep. The cover of this topper is composed of millions of microcapsules adapting constantly to your skin’s microclimate by absorbing, storing or releasing surplus body heat. These microcapsules form a buffer against overheating/perspiration as well as against becoming cold or shivering. The result is better body-temperature management to help keep you in deep sleep for longer so you wake up fully rested and ready to tackle the day. TempSmart™ is particularly recommended for those who have trouble maintaining a constant body temperature throughout the night but also those who reside in very hot and/or humid climates.

The core of the topper is composed of Innergetic® Latex with an open cell structure that ensures optimal air and moisture transportation. It is perforated throughout to ensure optimal ventilation with one side grooved and the other smooth, resulting in a softer and firmer side, respectively. Latex inhibits bacteria and dust mite, resulting in a cleaner and healthier bed climate.

Dacron Quallofil® Allerban® fibres in the topper cover also hinder the development of mould and dust mite.
