Bonnell Spring Mattress: the end diameter is large, and the middle diameter is small. The spring has strong resilience, excellent supporting performance and good force balance.
Pocket Spring Mattress: Olive type (waist drum type) spring is put into a special cloth bag independently. The spring point expansion and contraction, independent support, fit the human body curve, effectively support various parts of the human body, and disperse the pressure; Anti interference (does not affect sleeping partners) mute.
Spring in spring: the spring is packaged separately and sealed. There is a spring in the spring. Each spring responds to each movement of the body independently and does not interfere with each other.
Wire drawing lifting spring: It is made of a continuous steel wire, with the best force balance. It can make appropriate expansion according to the weight and body shape, support the body evenly, and increase comfort.
Open spring: The appearance is very similar to Bonnier spring, but the difference is that its end face is not knotted, and the vibration and load sensitivity of a single spring are better (good micro inductance, light pressure can be sensed), which can better offset human pressure and improve comfort.
Double layer spring: composed of two layers of Bonnier springs, the upper and lower layers share the weight of the human body. The upper layer of spring supports the weight of the human body and is effectively supported by the lower layer of spring. The force balance is better, and it can provide double support force and comfort. The spring will not collapse and has a longer service life.
Interlocking spring: refers to the mattress made by connecting individual springs to form a whole. Each spring is connected by a spiral snake line, which is divided into vertical and horizontal connection. The horizontal connection is that the snake line connects the spring along the parallel direction of the width of the mattress; The longitudinal connection is parallel to the length of the mattress, which has the advantages of good support and durability.
