The inflatable pad includes an inflatable frame having a length and width that defines a pad area suitable for supporting a person lying thereon. A plurality of internal support members are configured to support the weight of a person lying thereon and elevate the person above the ground. The inflatable pad includes non-supporting regions that require less fill volume than regions that support primary support regions such as the hips and shoulder.

1. An inflatable sleeping pad configured for supporting a person sleeping thereon, the inflatable sleeping pad comprising: a frame comprising a first sheet of material joined to a second sheet of material at a plurality of bond lines to form a plurality of fluidly connected air inflatable support members, each air inflatable support member defined between at least two bond lines of the plurality of bond lines, wherein at least some of the air inflatable support members are configured to support a person lying on the inflatable sleeping pad;a first valve coupled to the frame and in fluid communication with the air inflatable support members for inflation thereof;wherein the frame includes a pattern of non-supporting regions defined by non-inflating regions, the plurality of bond lines, and/or cutouts of the first and second sheets;wherein at least some of the bond lines comprise a rounded first end having a diameter, a flared second end having a width, and a transitioning portion therebetween, wherein the width of the flared second end is greater than the diameter of the rounded first end; andwherein the frame has a ratio of a fill volume/pad area in a range from about 0.4-4.0 ml/cm2 where the fill volume consists of the volume of air contained within the air inflatable support members at a pressure of 2 psi. 2. The inflatable sleeping pad of claim 1, wherein each non-supporting region has a length and width of at least 2 cm. 3. The inflatable sleeping pad of claim 1, wherein at least a portion of the non-supporting regions are provided in the form of the bond lines between the first and second sheets, each bond line including the rounded first end, and the diameter of the rounded first end is at least 10 mm. 4. The inflatable sleeping pad of claim 1, wherein the frame is elongate in a longitudinal direction and the pattern of non-supporting regions form a plurality of horizontal rows. 5. The inflatable sleeping pad of claim 1, wherein an average maximum vertical thickness of the support members is in a range from 2.5 cm to 8 cm. 6. The inflatable sleeping pad of claim 5, wherein the average maximum vertical thickness of the support members is at least 3 cm. 7. The inflatable sleeping pad of claim 1, wherein one or both of the sheets of material are a polyurethane or a polyester. 8. The inflatable sleeping pad of claim 1, wherein at least a portion of the support members are elongate and oblique. 9. The inflatable sleeping pad of claim 1, wherein a weight of the frame is less than 750 g. 10. The inflatable sleeping pad of claim 1, wherein the frame has a weight to surface area ratio less than 0.08 g/cm2. 11. The inflatable sleeping pad of claim 1, wherein: the first and second sheets are made from fabrics suitable for fabric welding;at least a portion of the non-supporting regions are bond lines with a width and length of at least 2 cm;the frame has a maximum width in a range from 40 cm to 60 cm and a maximum length in a range from 150 cm to 200 cm;a weight of the frame is less than 750 g; andan average maximum vertical thickness of the support members is in a range from 2.5 cm to 8 cm. 12. An inflatable sleeping pad configured for supporting a person sleeping thereon, the inflatable pad comprising: a frame comprising a first sheet of fabric material joined to a second sheet of fabric material to form a plurality of fluidly connected air inflatable support members, the frame having a maximum width of at least 40 cm and a maximum length of at least 150 cm, wherein a portion of the support members are configured to support a person lying thereon;a first valve coupled to the frame and in fluid communication with the air inflatable support members for inflation thereof;wherein the frame includes a repeating pattern of non supporting regions formed from fabric welds between the first and second sheets, the repeating pattern including rounded welds with a diameter of at least 10 mm; wherein a portion of the fabric welds comprise at least one of the rounded welds at a first end and a flared weld at a second end having a width, wherein the width of the flared weld is greater than the diameter of the at least one rounded weld, wherein the flared and rounded welds reduce torsion when the inflatable pad is inflated;wherein an average maximum vertical thickness of the support members is in a range from 2.5 cm to 8 cm;wherein the frame has a weight to surface area ratio less than 0.08 g/cm2; andwherein the frame has a ratio of a fill volume/pad area in a range from about 0.4-4.0 ml/cm2 where the fill volume is defined as the volume of air contained within the frame at a pressure of 2 psi. 13. The inflatable sleeping pad of claim 12, wherein one or both of the sheets of material are a polyurethane or a polyester. 14. The inflatable sleeping pad of claim 12, wherein the frame has a maximum width in a range from 40 cm to 60 cm and a maximum length in a range from 150 cm to 200 cm. 15. The inflatable sleeping pad of claim 12 wherein a weight of the frame is less than 750 g. 16. An inflatable sleeping pad configured for supporting a person sleeping thereon, the inflatable pad comprising: a frame comprising a first sheet of fabric material joined to a second sheet of fabric material at a plurality of fabric welds to form a plurality of fluidly connected air inflatable support members, each air inflatable support member defined between at least two fabric welds of the plurality of fabric welds, the frame having a maximum width of at least 40 cm and a maximum length of at least 150 cm, wherein at least some of the air inflatable support members are configured to support a person lying on the inflatable pad;a first valve coupled to the frame and in fluid communication with the air inflatable support members for inflation thereof;wherein an average maximum vertical thickness of the support members is in a range from 2.5 cm to 8 cm and the frame includes fabric welds between the first and second sheets, wherein the fabric welds taper from a flared end having an individual width to a transitioning portion, the transitioning portion located between the flared end and a rounded end having a diameter, the flared end being at least 5 mm in length and the fabric welds increase in width at least 2 mm from the transitioning portion to the flared end, wherein the individual width of the flared end is greater than the diameter of the rounded end;wherein a portion of the fabric welds comprise a flare toward one end of the fabric weld wherein the flare reduces torsion when inflated. 17. The inflatable sleeping pad of claim 16, wherein the fabric weld increases in width by at least 5 mm from the transitioning portion to the flared end. 18. The inflatable sleeping pad of claim 16, wherein the frame has a ratio of a fill volume/pad area in a range from about 0.4-4.0 ml/cm2 where the fill volume consists of the volume of air contained within the air inflatable support members at a pressure of 2 psi. 19. The inflatable sleeping pad of claim 16, wherein one or both of the sheets of material are a polyurethane or a polyester.
