As preferably, also comprise two rollers and the roller shaft that is connected two rollers, described roller shaft is located between two cross bars, and the inboard, middle part of described two cross bars is equipped with locating slot or the locating hole of positioning roller axle.Roller shaft stretches into locating slot or locating hole is propped chair, can alleviate the later sense of aching that produces of sitting, loosen health, can Effective Raise working and learning efficient.

As preferably, described locating slot or locating hole are to be located at the conduit that extends along cross bar to the foreleg direction on the madial wall of cross bar, described conduit is communicated with the upper surface of cross bar, the end face that is positioned at place in the middle of the cross bar on the described conduit formation vault that all upwards arches upward, described roller shaft enters conduit from the upper surface of cross bar and is stuck in vault cross bar is propped.Roller shaft is after the opening of conduit enters conduit and is stuck in the vault place that is positioned at the cross bar middle part on the conduit two cross bars are erected, and the people is sitting in the sensation that rocking chair is arranged on the chair, and is pleasant.When needs were moved chair, the vault place that only roller shaft need to be entered conduit propped chair, and the people hauls chair and walks about and get final product, and is more laborsaving, is particularly suitable for the physical less people such as the elderly, Ms; And chair and roller shirk conveniently.

As preferably, the end face that is positioned at cross bar and foreleg junction on the described conduit formation vault that also upwards arches upward, described roller shaft enters conduit from the upper surface of cross bar and is stuck in vault the link of cross bar and foreleg is propped.

As preferably, two rollers are between two cross bars.Simple and reasonable.

Beneficial effect:

A kind of seat that the present invention adopts technique scheme to provide, the gradient of seat support can regulate, movable, can effectively reduce the sense of aching that sitting produces later on, can loosen health, pleasant, energy Effective Raise working and learning efficient, simple in structure, economical and practical.
