Description

Elastic adjustment bed

The invention relates to a piece of furniture, in particular an elastically adjustable bed.

Background technique

The existing beds on the market are designed to improve the comfort of the bed. Generally, springs or sponge mattresses are added to the harder bed, but the elasticity and softness of the mattress are still not enough, especially in summer. Because it is airtight, it can't be used. In addition, some brown beds, rattan beds, and wire beds have softer bed surfaces. However, when used for a long time, the bed will collapse to the heavy load and cannot be restored. This will cause the body to stretch without being used for a long time. It affects the circulation of human blood and damages the health of the body; and the bed tension of the existing bed can not be adjusted, that is, its elasticity and softness cannot be arbitrarily changed, so it cannot meet the needs of different habits in various situations.
