Here's how the Sleep Balance TFK helps you get through the night

A spring core that adapts

Inside is a 7-zone barrel-shaped pocket spring core approximately 12 cm high, containing about 500 springs (for a 100×200 cm mattress). Each spring reacts independently—the core yields where pressure is applied and provides support where needed. The shoulder and pelvic zones are specifically contoured. This can reduce pressure points and keep the spine in a more natural position. For you, this means: you sleep more soundly and wake up less often feeling stiff.

Two mattresses in one—you decide

One side is softer, the other firmer: this reversible design ensures you get the most out of your mattress. If your sleeping experience changes, simply flip the mattress. Available in two combinations— H2/H3 (soft to medium-firm) and H3/H4 (medium-firm to firm). Which one is right for you depends on your weight, sleeping position, and preferences—the decision guide below will help you make the right choice.

Foam that makes all the difference

Each side of the spring core is topped with approximately 5 cm of foam. The softer side features supple 7-zone comfort foam (RG30)—soft and comfortable, ideal for lighter individuals. The firmer sides feature durable 7-zone hybrid foam (RG40), which provides more stable support while still relieving pressure. This way, you can help determine how your bed feels by choosing which side to sleep on.

A cover that stays fresh

The cover is quilted with moisture-regulating climate wadding and features an all-around climate band—this promotes air circulation and helps create a drier, more comfortable sleeping environment. You can completely remove the cover using the 4-sided zipper and wash it at up to 40°C. This ensures that the bed you lie down in at night stays hygienically fresh.

How does it feel to lie down?

To be honest: The Sleep Balance TFK is more supportive and springy than deeply sinking. The pocket spring core provides feedback, while the foam layer absorbs the initial firmness. On the softer side, it cradles you a bit more; on the firmer sides, you feel noticeably more stable. If you’re looking for a very soft, almost enveloping mattress, you’re better off looking elsewhere—we’ll be honest about that. But if you want a balanced, well-ventilated mattress whose firmness you can adjust yourself, this is exactly what you’ll find here.

How to find the right model for you

• Body weight: Lighter people often find the softer sides more comfortable, while heavier people prefer the firmer ones.
• Sleeping position: Side sleepers need more relief for their shoulders and hips, while back sleepers need continuous support.
• Hardness combination: H2/H3 for soft to medium, H3/H4 for medium to firm.
• Shared use: With double beds, the reversible design helps accommodate different preferences.
