The best comfort for your bed

With the CosyLift, you can easily transform your bed into an electrically adjustable multifunctional space. It’s ideal for gamers, students, streaming, nursing moms, home office set-ups, and of course, anyone who would rather just spend the day in bed. With the best quality from Cosyworld, you can take your comfort to the next level – developed in Germany, produced in Europe.

Small, powerful and comfortable: The upgrade for your bed

  • The CosyLift is suitable for all beds and all mattresses with a width of 80 to 120 cm. For mattresses with a width greater than 120 cm, two CosyLifts can be combined and controlled simultaneously using the Synchro cable (also available here in the shop). The Synchro cable is essential for a double bed with a full-length mattress.
  • The CosyLift can be adjusted electronically from 0 to 59° with intermittent steps and by hand switch. It can also be controlled via app (using a required Bluetooth dongle). The app is available for free download on the App Store and Google Play.
  • The patented drive technology in the CosyLift is whisper-quiet, which means you can barely hear the motor as you adjust the lift.
  • The CosyLift weighs just 9.5 kg and can lift an area load of up to 150 kg (distributed over the entire lying surface of the bed).
  • The dimensions of the CosyLift are 102 x 70 x 3 cm; in the engine area, it has a height of 6.5 cm. That means it can be placed in a handy package and delivered by post.
  • The CosyLift was developed in Germany and is produced in Europe. The short supply chains enable the best quality for your home.

The press is also impressed by the CosyLift

With it, I transform my normal sleeping place into a wellness oasis. Via a button, the electric motor lifts the mattress, even if it weighs up to 150 kilos. The whole thing is compatible with all bed constructions, including box spring beds.

Frequently asked questions

The CosyLift is suitable for anyone who wants to adjust their bed electrically and experience more comfort. It fits into any bed.
The CosyLift is a multifunctional addition to any bed. If you have a slatted frame bed, you do not have to replace or even throw away your slatted frame base. It can simply be placed under the mattress on the spring strips of the slatted frame base.
With the CosyLift, you can also adjust your double bed electrically. A single CosyLift measures 102 cm (length) x 70 cm (width) x 3 cm (height) and can be combined with a mattress width of up to 110 cm. If you want to electrically adjust wider mattress sizes or two individual mattresses next to each other, you can connect and synchronize two CosyLifts with our synchronization cable. This allows you to adjust the double bed evenly over the entire width. You can get the necessary cable as an optional accessory in our shop.
The CosyLift has been extensively tested in our laboratory and is equipped with a patented drive technology, which is certified by TÜV and is CE-compliant. It’s also equipped with a mechanical emergency lowering. If the power fails or a malfunction occurs, it can be lowered manually with two handles. Further information can be found in the instructions in our video tutorial.
