A furniture system for optimizing sound levels and acoustics in a learning environment. The system includes a plurality of pieces selected from a toy shelf, a bridge/tunnel structure, a sandwich board shelf unit, a tunnel with interior shelves, a toy box with leaning bendable posts, a bench/tunnel with combination seat, tunnel, and shelf, a listening center, a stealth chair/cave structure, stealth leaning surface/cave, a multifunctional zigzag chair, and a multipurpose chair/easel.

The present invention is directed to a novel workstation which incorporates an acoustical dome for increased acoustic and visual privacy for the user. The workstation further is adjustable in height such that it is able to accommodate a range of users from the 5.sup.th percentile seated female to the 95.sup.th percentile standing male according to the dictates of ANSI/HFES100-2007 national ergonomic standard. The workstation is further designed to be in electrical and data communication with other workstations to optimize the workstation density in an open working environment without compromising user privacy.

The present invention is a secure work pod that is a flexibly private, moveable, personal office. The secure work pod allows a user to have visual and acoustic privacy in an otherwise open workspace. The secure pod is constructed of flat panels that are constructed in a workspace by connectors that allow for 90-degree connections of the panels. Panels may have windows for visibility inserted in the front and back panels. The windows may have semi-glazed windows for privacy or may be left open. The work pod has an acoustic door that provides privacy for the user. The secure work pods can be organized into small layouts having a few pods or in large layout neighborhoods having multiple work pods.

A damper with hidden rail, comprising a shell and a damper, the damper comprises a tension piece, a sliding block, a telescopic cylinder and a limiting piece, the sliding block is slidably mounted in the shell, and the tension piece is connected to the shell and the sliding block; the tension piece is capable of pulling the sliding block to move; the limiting piece is connected to the sliding block, and the telescopic cylinder is mounted on the shell; the limiting piece is provided with a compression surface, one end of telescopic cylinder abuts against the compression surface directly or indirectly, and the telescopic cylinder and the limiting piece have a first relative position and a second relative position; in the process that the tension piece pulls the sliding block, the telescopic cylinder moves; and in the process that the telescopic cylinder moves, the telescopic cylinder is gradually compressed.
