Jensen Signature J4 Lean

Most of our beds can be ordered with adjustable functionality through either the introductory Jensen Dream or the more luxurious Jensen Active II. If you experience recurring body aches this type of bed is an especially interesting choice, but anyone can benefit from its functionality. As we go through life we all experience change to our bodies, making it a great advantage to be able to change the way your bed gives support to your current needs. With just the push of a button you can raise or lower the bed from both ends to adjust the bed to your liking. 

The adjustable bed also opens up for using the bed in new ways, for example watching TV or reading with comfort that is simply on another level. 

Jensen Lean has all the advantages of an adjustable bed – but without the bulky design. The low base gives an elegant impression while our new Ease-concept provides unique qualities in both sleep comfort and bed care. The mattress and frame are assembled as a single piece of furniture, preventing the mattress from sliding while you sleep. The innovative Ease-concept also features a connected double spring system that does not need turning the mattress to keep its lifespan intact.

The Jensen J4 is sleep comfort made affordable. The inclusion of the Aloy® 2.1 spring system sets it apart from the lower models in the J-series. Despite the slight decrease in spring height compared to the J5, (12,5 cm) it still offers the great feeling of sinking into the mattress while receiving accurate support. High quality materials and fabric colours inspired by Norwegian nature makes the J4 the centerpiece of your bedroom. 

J4 is equipped with the Aloy® 2.1 Spring System (12,5 cm) that supports and adapts to your body. The extra soft and long shoulder zone provides great flexibility and space for your shoulders. The spring system also features built-in support for the lower back. 


 The headrest function adapts the bed so that your neck and head are always in the right position when sitting upright. 

 Stepless adjustment up/down for both head and foot end, individually or together. 

 Two beds can be connected and controlled in sync by one remote.

Jensen Aloy® 2.1 Spring

The spring system softens the entire mattress surface, since the firmer zones only come into function when your body sinks into the mattress.

Did you know that the shoulder joint is the most flexible of the body, and that this area is the one most exposed to injuries? This unstable joint is constantly exposed to pressure, especially if you sleep on your side. That is why we are launching Aloy® 2.1. The secret is an upgraded Aloy® spring system, with an extra soft shoulder zone - that gives your shoulders plenty of space.
