A moveable anti-fatigue mat that can be moved by a user's foot without the need for the user to bend over. In one embodiment, the anti-fatigue mat comprises a cushioned top layer affixed to a high friction bottom layer, wherein a low friction activation pad is positioned on or within the bottom layer. The activation pad can be attached so that a bottom surface protrudes below or is flush with the bottom surface of the bottom layer, and the activation pad is preferably located near the edge of the bottom layer. The anti-fatigue mat may be slid laterally on a floor or surface by a user's foot when a user places his foot on the mat directly above the activation pad and applies pressure downward and in the direction the user wishes the mat to move.

A pad is provided for supporting heavy loads and is capable of supporting loads of 100 tons or more. The pad has a core having a bi-directional grid formed from parallel fiberglass materials, with a first set of material at right angle to a second set of fiberglass materials and which grid surrounds a closed cell material, which is infused with resin to form a core. A fiberglass top surface, bottom surface and at least one sidewall is provided. The result is a pad able to distribute very heavy loads, is resistant to bending, durable and light weight.

Mat (10) for gymnastics and physical rehabilitation and re-education, apt to perform appropriate treatment in order to strengthen and re-educate the muscle and tendon structure of the human body. The mat is made from a tray delimited by a perimetric frame (70) of polyethylene containing at least one layer (90) of viscoelastic or memory, glued on underlying layers (80) of polyethylene and polyurethane glued together, always contained inside the said tray, and at least one step removable (100, 200) and repositionable firmly on the mat, and at least one insert (300) also removable and repositionable firmly into the mat. The perimetric frame of density higher than of the layers of the material contained, allows the feet resting astride the perimetric frame, a flexion movement, extension of the tibiotarsal articulation along its transverse axis, exerting a pressure massage due to the body weight standing upright on the foot plant, at vascular vesicles level, obtaining a venous return increase.

In some embodiments, the inventive subject matter is directed to an arrangement of discrete elements of fill material on a substrate consisting of a sheet material wherein the discrete elements are fixed relative to the sheet material by pilings, fusion, and/or entanglement to fix the insulating elements in a layered arrangement over the sheet material. A second sheet of material may be used to create a sandwiched assembly of the discrete elements. In some embodiments, the inventive subject matter is generally directed to discrete elements of fill material that are engaged together to form a cohesive sheet-like or layered arrangement of the elements.

A lightweight sound absorbing surface material, having an excellent sound absorbing property and moldability, and a sound absorbing material using the sound absorbing surface material, are provided in the present invention. The sound absorbing surface material 6 is manufactured by laminating stretchable paper(s) which is (are) creped and/or embossed (such as a creped paper 1b) onto one or both sides of a fiber sheet 3. The degree of creping of the paper is in the range of between 10 and 50 %, and the height of projections of the embossed paper is in the range of between 0.02 and 2.00 mm, with the number of the projections being in the range of between 20 and 200 projections/cm 2 . Further, the sound absorbing surface material 6 is laminated onto a air permeable sheet of porous material 7, to manufacture a sound absorbing material 8.
