To give this true Hybrid pocket-unit an unequalled flexibility we have taken away the need for any further top layers in a bed or mattress.

By fusing a smooth latex pillow on top of every single coil this spring unit will adapt to the shape of your body in a sensational way.


Do you already know our most flexible spring unit? By varying the coil preload, instead of using different wires as in traditional zones, we can secure a distinct difference between the zones whilst keeping a smooth transition from one zone to another. This gives you as bed maker the possibility of in one spring unit using three different firmnesses that you can divide in an almost unlimited amount of zones. Now you can create a unique and perfectly designed zoning in so that you can build the best bed or mattress ever.

How to build the S-matic cassette in to a mattress

The S-matic is a new technology, but it’s easy to make adjustments on the surrounding materials to build a traditional bed or mattress. And these are probably the greatest strengths of the S-matic.


We are always trying to help our customers to be the forefront in the latest technology. Right now we at Starsprings are convinced about what is the future in bedding technology. It is not about digital solutions or gadgets. It is about improved sleep, better health. It is about adjustable firmness.

Adjustable firmness will help every single user to adjust the mattress to fit the body shape and taste.


"My name is NilsEric Stjerna. I am the CEO of Starsprings.

Five years ago we decided to find out exactly the unsatisfied needs that people have regarding sleeping and mattresses. We let an independent company perform market surveys in several countries.

The results from the market investigation are very clear. If we develop products that solve the problem and have a reasonable cost and good quality, we will have a product that can be a game changer in the bedding market. After several years of development and testing, I now welcome the S-Matic.
