The angle can be manually adjusted in 14 steps from 9 to 23 degrees according to your physical condition.
The base of the main unit has a hammock-like structure made of a rectangular metal frame with tapes about 1 cm wide stretched in a grid pattern. Urethane is applied on top of this, so it sinks like a sofa, enveloping your body for a soft sleeping experience. This makes it softer than the sister product, Rakuui.
It is lightweight at 4.0 kg, making it easy to store and move. The inner cover is antibacterial and deodorizing, and the outer cover is made of absorbent and quick-drying fabric. Both covers can be removed and washed, ensuring cleanliness.

2. For beds, place the unit under the mattress to prevent the metal plate at the waist from pressing against your body.
3. If your mattress is thick or hard, place the unit on top of the mattress and then place a bed pad or similar item on top before sleeping.
