A resilient mat system where a mat has overall mat thickness T, and the mat has an upper layer with an upper layer thickness t, and a plurality of supporting resilient substructure columns, each column having a relatively uniform height h, such that T=t+h, wherein the ratio of h:t>3.5 for values
A resilient mat system where a mat has overall mat thickness T, and the mat has an upper layer with an upper layer thickness t, and a plurality of supporting resilient substructure columns, each column having a relatively uniform height h, such that T=t+h, wherein the ratio of h:t>3.5 for values of T>about 0.9 inch. Each column has a column wall that surrounds a central void in the column with the void opening at a bottom of the column. The column has lower zone that is a more compressible, relatively collapsible zone, and an upper zone that is a less compressible, relatively uncollapsible zone. There is a fenestrated mat connector with connector fenestrations sized and numbered to receive the bases of a plurality of columns from two mats therein.

We claim: 1. A resilient mat system comprising at least one mat, the mat having a mat thickness T, the mat having an upper layer with an upper layer thickness t, the mat further comprising a plurality of supporting resilient substructure columns, each column having a relatively uniform height h, such that T=t+h, wherein the ratio of h:t>3.5 for values of T>about 0.9 inch (2.3 cm); each column having a column wall, the wall surrounding a central void in the column, the void opening at a bottom of the column, the column having in a bottom region of the column wall a lower zone that is a more compressible, relatively collapsible zone, and in an upper region of the column wall above the lower zone an upper zone that is a less compressible, relatively uncollapsible zone; the mat system further comprising a ramp structure bordering at least one mat on at least two sides, at least a portion of the ramp structure attached to the mat; the mat system further comprising a fenestrated connector, the connector fenestrations sized and numbered to receive the bases of a plurality of columns therein, the connector having a bend forming a lip wherein an edge of the ramp is interengaged for attachment of the ramp to the mat. 2. The mat system of claim 1 further comprising a set of single ribs connecting a peripheral outer border of columns to a base of the integral ramp. 3. The mat system of claim 1 further comprising a vertical stiffening rib along a portion of the upper zone of the column wall. 4. The mat system of claim 1 wherein the column is tapered upwardly, both inside and out, with an outside draft angle>1 degree and <5 degrees, and an inside draft angle>0 degrees and <5 degrees. 5. The mat system of claim 4 wherein the outside draft angle is greater than the inside draft angle. 6. The mat system of claim 1 wherein the substructure is comprised of elastomeric material having compression modulus of between 0.5 and 0.9 and a Shore A durometer of 40-50. 7. A resilient mat system comprising at least one mat, the mat having a mat thickness T, the mat having an upper layer with an upper layer thickness t, the mat further comprising a plurality of supporting resilient substructure columns, each column having a relatively uniform height h, such that T=t+h, wherein the ratio of h:t>3.5 for values of T>about 0.9 inch (2.3 cm); each column having a column wall, the wall surrounding a central void in the column, the void opening at a bottom of the column, the column having in a bottom region of the column wall a lower zone that is a more compressible, relatively collapsible zone, and in an upper region of the column wall above the lower zone an upper zone that is a less compressible, relatively uncollapsible zone; the mat system further comprising a fenestrated connector, the connector fenestrations sized and numbered to receive the bases of a plurality of columns from at least two mats therein, such that with column bases of two mats engaged within the fenestration of the same connector, the two mats are thereby joined in a selected spaced relationship. 8. The mat system of claim 7 further comprising an integral ramp upon at least one edge of the mat. 9. The resilient mat system of claim 8 further comprising a set of single ribs connecting a peripheral outer border of columns to a base of the integral ramp. 10. The mat system of claim 7 further comprising a ramp structure bordering at least one mat on at least two sides, the ramp structure attached to a floor base to retain the mat, whereby the mat is removable from the border of the ramp. 11. The resilient mat system of claim 7 wherein the selected spaced relationship is for the two mats to be held to have a selectably sized gap between them, the width of the gap depending upon the spacing of the fenestrations in the connector. 12. The mat system of claim 7 further comprising a vertical stiffening rib along a portion of the upper zone of the column wall. 13. The mat system of claim 7 wherein the column is tapered upwardly, both inside and out, with an outside draft angle>1 degree and <5 degrees, and an inside draft angle>0 degrees and <5 degrees. 14. The resilient mat system of claim 13 wherein the outside draft angle is greater than the inside draft angle. 15. The mat system of claim 7 wherein the substructure is comprised of elastomeric material having compression modulus of between 0.5 and 0.9 and a Shore A durometer of 40-50.
