Most mattresses support you evenly — but your body isn't evenly weighted. Your hips and waist carry the most mass, and that's exactly where an ordinary mattress gives out first: it hollows, your lower back loses its line, and you wake up stiff.
The SK-2601 is built around that problem. Its coil unit is split into five zones, and the comfort layers above are genuinely medium-soft — around 4.5 to 5 out of 10.
1 · Five Zones, Two Wire Gauges
Each coil is wrapped in its own fabric pocket and moves independently, so the zones work separately rather than pulling on each other. Weight is distributed where it actually falls, and movement is absorbed at the source — a partner turning over doesn't send a ripple across the bed.
2 · 9.5 cm of Comfort, Quilted In
Quilted into one panel rather than stacked loosely, so the surface stays flat and even over time. Total profile: 31 cm.
3 · 7 cm of Foam Around the Edge
The perimeter is where ordinary pocket spring beds fail first. This one uses a 7 cm-wide #35 high-density foam encasement — a solid foam rail, not just heavier springs. Sitting on the edge feels solid, the full width is usable (a Queen genuinely feels wider), and the bed resists the outward bulge that develops over years.

Side sleepers · lighter body weights · anyone whose lower back feels unsupported on a uniform-firmness bed · couples who want less disturbance.
Back and stomach sleepers over about 230 lb (105 kg) will usually prefer something firmer.
Single-sided — never flip it, just rotate 180° every 3–6 months. Arrives compressed and roll-packed in one reinforced carton: sleepable within hours, full height in 24–72 hours. A faint new-mattress smell for a day or two is normal; ventilate and it clears.
At 31 cm, this is a tall mattress — deep-pocket or "extra deep" fitted sheets are recommended. Standard sheets may not tuck fully under the corners.
Because the comfort layers are thicker than a standard bed, give it two to three weeks to settle; it will feel slightly softer as the foams break in.

What does 5-zone lumbar support do? It puts firmer coils under your waist — the heaviest part of your body — and softer coils under your head, shoulders and legs, so your spine stays level instead of sagging in the middle.
How soft is medium soft? About 4.5–5 out of 10 — cushioned on first touch, but it doesn't swallow you.
Is 31 cm too thick for my sheets? It's about 12 inches, so deep-pocket or "extra deep" fitted sheets are recommended. Standard sheets may not tuck fully under the corners.
Do I need to flip it? No. Single-sided — just rotate head-to-foot every few months.
How long until it's ready? Sleepable within hours; full height in 24–72 hours.
