A taller Lifestyle tight-top mattress with a 16 cm 5-zone pocket-spring core.
Relax is the middle construction in the Lifestyle progression. It keeps the straightforward tight-top format used by Cozy but increases the 5-zone pocket-spring core from 12 cm to 16 cm.

Relax stays simple in its surface layering while providing a taller spring core than Cozy. It remains less layered than Fresh, which adds latex, an additional foam layer and a Euro top.
Consider Relax if you…
Relax uses a 16 cm 5-zone pocket-spring core versus Cozy's 12 cm core.
The model keeps the quilted-surface and felt-layer direction simple.
The workbook specifies a 5-zone pocket-spring system with 5 cm 3080# foam encasement.
Moving down to Cozy: choose the simpler / lower construction if you do not need the added layers or top-design changes in Relax.
Moving up to Fresh: choose it if you want the additional verified construction layers or deeper build introduced above Relax.
