Head support pad with air access conduit

A support pad comprising:

• (A) a generally planar upper support surface, a generally planar lower surface, pad side walls joining said upper support surface to said lower surface, an inferior end and a superior end, which in combination define a pad for supporting the torso and head of a user in the face-down, prone position wherein said inferior end is shorter than said superior end such that said support pad is generally wedge-shaped;
• (B) a generally U-shaped face recess positioned in said upper support surface and extending through said pad through said lower surface, said recess comprising opposing recess side walls defining a breathing void in said pad and a recess open end extending through said superior end, said recess having a configuration to receive the face of a user while laterally supporting the user's head;
• (C) a pair of internal air flow conduits positioned within said pad, one of said pair of air flow conduits having an exterior opening in one of said pad side walls and a recess opening in one of said recess side walls, and the other of said pair of air flow conduits having an exterior opening in the other of said pad side walls and a recess opening in the other of said recess side walls;
• and
• (D) filter means combined with said pair of internal air flow conduits to prevent particulate matter from entering said pair of air flow conduits.
