0.25英寸到大约3英寸宽之间，最好在大约0.35英寸宽到大约2英寸之间英寸宽，甚至更好的是在大约0.45之间英寸宽，约1英寸宽，并具有高度在约5英寸和约12英寸之间，优选在大约7英寸到大约10英寸之间，甚至更大优选在约8英寸至约9英寸之间。其他尺寸也可以使用。在所示的实施例中，中间台阶大约14英寸宽，大约7英寸长，坐在大约8英寸的高度，上面有支撑24a和24b的宽度约为0.5英寸，约为8.5英寸高。可选地，中间台阶30可以包括上表面32，该上表面32具有具有适当的摩擦系数以阻止正常使用期间的运动或滑动的材料（在本文中也称为“防滑”表面或材料）。这样的材料可以仅附接到中间台阶30的某些部分或仅施加到中间台阶30的某些部分。例如，在所示的实施例中，每个桌脚2la-1d具有施加到其底侧的相应的防滑材料32。4.0示范性的上级台阶34参照图2，图1的示例性可转换家具片10的上部台阶40的透视图。显示了1。上台阶40可以包括可以是基本上平坦的上表面42。优选地，上台阶40固定地附接到基座21。例如，在所示的实施例中，上台阶40通过桌腿26c和26d固定地附接到基座21的桌脚22c和22d。在一些实施例中，基本上所有的上台阶40都位于底座所限定的覆盖区的正上方。通过将基本上所有的上台阶40保持在基部21的覆盖区的正上方和/或通过将上台阶40固定地附接到基部21，来增加部件10的稳定性。上台阶40用作台阶或办公桌/工作区域。如上所述，上部台阶40也可以附接到中间台阶40，并且优选地可以
