CLAIM OF PRIORITY [0001] This application claims the benefit of U.S. Provisional Application No. 60/736,103, filed on Nov. 10, 2005 and the benefit of U.S. Provisional Application No. 60/784,059, filed Mar. 17, 2006, both of which are incorporated by reference. FIELD OF THE INVENTION [0002] This invention relates to seats that include heating, cooling or ventilation, and more particularly to vehicle seats that include a cushioning layer that increases the comfort of the seat. BACKGROUND OF THE INVENTION [0003] For many years the transportation industry has been concerned with designing seats for automotive vehicles that provide added comfort to occupants in the seats. Various innovations in providing seating comfort are discussed in U.S. Pat. Nos. 6,893,086; 6,872,882; 6,869,139; 6,857,697; 6,828,528; 6,676,207; 6,619,736; 6,439,658; 6,164,719; 6,064,037; 5,921,314; 6,064,037; 5,921,314; 5,403,065; 6,048,024 and 6,003,950, all of which are expressly incorporated herein by reference. In addition, other innovations in providing seating comfort are discussed in U.S. Publication No. 2002/0096931, filed Jan. 5, 2001, titled "Ventilated Seat"; U.S. Pat. No. 6,629,724, issued Oct. 7, 2003, titled "Portable Ventilated Seat"; U.S. Patent Publication 2004/0070236, filed Oct. 8, 2003, titled "Automotive Vehicle Seating Comfort System", U.S. Patent Publication 2005/0067862, filed: Apr. 12, 2004, titled "Ventilated Seat"; and U.S. Patent Publication 2005/0066505, filed: Apr. 12, 2004, titled "A Method For Ventilating A Seat", each of which are expressly incorporated herein by reference for all purposes. [0004] In the interest of continuing such innovation, the present invention provides an improved insert and system for a seat, which are preferably suitable for employment within or as part of an automotive vehicle seat and which assist in providing comfort control to an occupant in the seat. SUMMARY OF THE INVENTION [0005] The present invention includes a seat for a vehicle having at least one temperature conditioned component. The temperature conditioned component comprises a cushion, a trim surface, an insert located beneath the trim surface and a cushioning layer. The cushioning layer comprises one or more pouches with a filler material, and preferably a liquid filler material, that distributes the downward pressure of the occupant across a larger area of the seat. This distribution of downward pressure reduces or eliminates pressure points in the seat. The seat may also include an air mover assembly that facilitates the heating, cooling or ventilation function of the seat by blowing air to or drawing air from the seat. BRIEF DESCRIPTION OF THE DRAWINGS [0006] In the drawings: [0007] FIG. 1 shows a perspective view of one embodiment of a pouch useful in a cushioning layer, the pouch having through holes; [0008] FIG. 2 shows a top view of one embodiment of a ventilating insert with a cushioning layer located on the occupant side of the insert; [0009] FIG. 3 shows a perspective view of a non-ventilating insert with a cushioning layer on a base layer; [0010] FIG. 4 shows a cross section of a pouch in a non-ventilating insert attached using rivets; [0011] FIG. 5 shows a cross section of a pouch in a non-ventilating insert attached using two-sided tape; [0012] FIG. 6 shows a cross section of a pouch in a non-ventilating insert attached using welding to a polyurethane film; [0013] FIG. 7 shows a cross section of a pouch in a non-ventilating insert attached using an adhesive; [0014] FIG. 8 shows a cross section of a pouch in a non-ventilating insert attached using a sewing method; [0015] FIG. 9 shows a top view of a pouch attached using a sewing method with a heating element. DETAILED DESCRIPTION [0016] Vehicle seats may comprise at least one temperature conditioned component such as a seat component, a backrest component, a bolster, an armrest, a headrest or the like. In one embodiment, the temperature conditioned component is a non-ventilated component which does not utilize a mechanism to move air into, out of or through the component. Each non-ventilated component may provide heating, cooling or combinations thereof to the occupant. For example, a heating element may provide heat to the occupant. [0017] In another embodiment, the temperature conditioned component is a ventilated component which utilizes a mechanism to move air into, out of or through the component, such as a blower in an HVAC system of the vehicle or a blower in the seat. Each ventilated component may provide heating, cooling, ventilation or combinations thereof to the occupant. For example, a blower may blow cooled air from a thermoelectric device to the occupant. [0018] Each temperature conditioned component comprises a cushion and a trim surface to cover the component, as well as an insert. The insert may be a non-ventilating insert or a ventilating insert. The present invention relates to a cushioning layer for incorporation into the seat, and preferably, for attachment to or incorporation into the insert.
