Luxus Premium keeps the multi-pocket spring core of the base Luxus - zoned, individually wrapped springs that respond to where your body actually presses - and thickens the comfort build above it: 1cm of coconut fibre plus 3cm of latex, a full centimetre deeper than the entry model's 2cm.
That extra latex buys more cushioning before the firmer spring layer is felt underneath. The firmness rating itself does not move - still medium-firm (4/5), so it remains best matched to back and stomach sleepers, and to heavier builds, exactly as the base Luxus is; only the amount of give above the springs changes.
Think of it as the middle ground in the Luxus range: more cushioning than the entry model for anyone who found its 2cm layer thin, without going as deep as Luxus Supreme's 4cm. Cover, size options and spring construction otherwise carry over unchanged from the rest of the family - linen-and-Tencel knit, identical feel whichever face you sleep on.
MattressCenter covers it for 5 years, and if the medium-firm feel needs adjusting after delivery, the comfort layer alone can be swapped within the first 30 nights.
