Details

The Relax Sensac Mattress is the most sophisticated model in Relax's pocket spring collection. It brings together a Spiral Adapt pocket spring core for exceptional motion isolation, Visco Gel thermoregulating layers, and an exclusive textile technology that sets it apart from anything else in the range: the Relax Antistress Ion Repair system.

The Stretch fabric with Ion Repair treatment integrates a technology that releases negative ions gradually during sleep. These negative ions are known to help improve sleep quality, reduce accumulated fatigue and anxiety, and promote a more restorative and refined sleep experience night after night.

The Spiral Adapt pocket spring core delivers outstanding motion isolation: each spring responds independently to the weight of each body zone without transferring movement from one side to the other. The Relax Square perimeter reinforcement protects the edges, prevents lateral sagging, and maximises the usable sleep surface.

The comfort layers combine Visco Gel foam with memory effect and gel particles that regulate body temperature, alongside Confort Super Soft for an enveloping feel, Confort Medium for a progressive transition, and Confort Firm for a stable base. Together they deliver high firmness and excellent breathability. The mattress features a Tapa-Tapa reversible design — same configuration on both sides — which extends its useful life and ensures even wear over time.

Available at Colchón Exprés with free delivery, installation, and removal of your old mattress. If you're looking for a similar model with a summer/winter double-sided design, take a look at the Relax ThermoBalance.

Couples sharing a bed: the Spiral Adapt pocket springs ensure one sleeper's movement won't disturb the other.
Active and sporty sleepers: the combination of high firmness, adaptability, and excellent breathability supports recovery.
