Details

The Flex WBx FIT Pocket Mattress is the most complete model in Flex's Wellness BioCeramics® range for those who want independent spring support without giving up active recovery technology. It combines a Pocket Premium® Top spring core with the exclusive Stretch BioCeramics® upholstery — a technical fabric that integrates bioceramic particles capable of emitting long-range infrared (FIR) waves to boost cellular hydration, stimulate circulation, and accelerate tissue recovery while you sleep.

Its individually encased Pocket Premium® Top spring core — 17 cm deep — delivers excellent motion isolation: each spring responds independently to the weight of each body zone without transferring movement across the surface. This makes it the ideal choice for couples with different sleep schedules or habits, or for anyone who moves frequently during the night.

The Zone Support Pro® system differentiates three sleeping zones with varying firmness levels, providing targeted lumbar reinforcement and adapting to different body areas for optimal spinal support. The gel viscoelastic upholstery adds a fresh surface feel and reduces pressure points, while Commodo+® delivers progressive cushioning, Total Protect provides antibacterial protection, and hypoallergenic fibres complete the comfort package.

At medium-high firmness and 32 cm in height, the Flex WBx FIT Pocket is built for sleepers who want the balance of support and adaptability — with the added benefit of an active recovery fabric that sets it apart from any other pocket spring mattress on the market. Available at Colchón Exprés with free delivery, installation, and removal of your old mattress. If you prefer greater firmness without independent springs, explore the Flex WBx FIT Multielastic.

Who is it recommended for?

Couples who need motion isolation: one sleeper's movement won't disturb the other.
Physically active people seeking active muscular recovery during sleep through BioCeramics® FIR technology.
Those with lower back discomfort: Zone Support Pro® provides targeted reinforcement across three differentiated zones.
Restless sleepers: the pocket springs absorb movement locally without transmitting it across the surface.
Sleepers who want more precise adaptability than a continuous coil system offers, at medium-high firmness.
