1. A collapsible chair comprising: a base and a back connected along a hinge, which hinge comprises a central hinge portion, a first and a second hinge end, and a hinge axis of rotation, the base being configured to collapse around an axis perpendicular to the hinge axis of rotation when the collapsible chair is not occupied but strong enough along the hinge axis of rotation to help prevent planar deformation of the base when the collapsible chair is occupied;a first adjustment strap connected to a first corner of the base distal to the hinge and connected to a first corner of the back distal to the hinge, wherein the first corners of the base and back distal to the hinge are configured to support the base on a first adjustment strap plane perpendicular to the hinge axis of rotation when the collapsible chair is not rolled up;a second adjustment strap connected to a second corner of the base distal to the axis and connected to a second corner of the back distal to the axis, wherein the second corners of the base and back distal to the hinge are configured to support the base on a second adjustment strap plane perpendicular to the hinge axis of rotation when the collapsible chair is not rolled up and when the first and second adjustment strap planes are parallel;a top strap comprising a top strap fastening device, which top strap fastening device may be used to releasably attach the collapsible chair to a luggage;a side strap comprising a side strap fastening device, which side strap may releasably encircle the luggage;a first closure along a first perimeter of the base between the first corner of the base distal to the hinge and the first hinge end, along a second perimeter of the back between the first corner of the back distal to the hinge and the first hinge end, along a third perimeter of the base between the first corner of the base distal to the hinge to a middle of a side of the base distal to the hinge, and along a fourth perimeter of the back between the first corner of the back distal to the hinge to a middle of a side of the back distal to the hinge; anda second closure along a fifth perimeter of the base between the second corner of the base distal to the hinge and the second hinge end, along a sixth perimeter of the back between the second corner of the back distal to the hinge and the second hinge end, along a seventh perimeter of the base between the second corner of the base distal to the hinge to the middle of the side of the base distal to the hinge, and along an eighth perimeter of the back between the second corner of the back distal to the hinge to the middle of the side of the back distal to the hinge, wherein the first and second closures may close at least one set of corresponding perimeters of the base and back together. 2. The collapsible chair of claim 1, further comprising: a first rigid stay and a second rigid stay within the base, wherein the first and second rigid stays are perpendicular to the hinge axis of rotation. 3. The collapsible chair of claim 1, wherein the collapsible chair is configured as a backpack. 4. The collapsible chair of claim 1, wherein the base is folded around the axis perpendicular to the hinge axis of rotation so that the collapsible chair is configured to be stowed away in a pocket of the luggage. 5. The collapsible chair of claim 1, wherein the base includes padding configured to help prevent planar deformation of the base when the collapsible chair is occupied and also configured so that the base can collapse around the axis perpendicular to the hinge axis of rotation when the collapsible chair is not occupied and not connected to the luggage. 6. The collapsible chair of claim 1, wherein the base contains rigid stays configured to keep the base from folding on itself and wrinkling when the collapsible chair is occupied and also configured to collapse around the axis perpendicular to the hinge axis of rotation when the collapsible chair is not occupied and not connected to the luggage. 7. The collapsible chair of claim 1, wherein the base contains rigid stays perpendicular to the axis of rotation but does not contain rigid stays along the hinge axis of rotation, the rigid stays perpendicular to the axis of rotation configured to keep the base from folding on itself and wrinkling when the collapsible chair is occupied and also configured so that the base can collapse around the axis perpendicular to the hinge axis of rotation when the collapsible chair is not occupied and not connected to the luggage. 8. The collapsible chair of claim 1, wherein the base is rolled up around the axis perpendicular to the hinge axis of rotation and wherein the collapsible chair is not occupied and not connected to the luggage. 9. The collapsible chair of claim 1, wherein the top strap fastening device releasably attaches the collapsible chair to the luggage, wherein the top strap forms a loop that goes around a telescoping handle, the telescoping handle being an attachment point on the luggage. 10. The collapsible chair of claim 1, wherein the top strap includes a length adjustment mechanism built into a buckle of the top strap whereby the top strap is adjustable in length to accommodate the size of the luggage. 11. The collapsible chair of claim 1, wherein the top strap includes a length adjustment mechanism that includes one or more removable lengthening pieces of the top strap whereby the top strap is adjustable in length to accommodate the size of the luggage. 12. A collapsible chair comprising: a base and a back connected along a hinge, which hinge comprises a central hinge portion, a first and a second hinge end, and a hinge axis of rotation, the base being configured to collapse around an axis perpendicular to the hinge axis of rotation when the collapsible chair is not occupied but strong enough along the hinge axis of rotation to help prevent planar deformation of the base when the collapsible chair is occupied;a first adjustment strap connected to a first corner of the base distal to the hinge and connected to a first corner of the back distal to the hinge, wherein the first corners of the base and back distal to the hinge are configured to support the base on a first adjustment strap plane perpendicular to the hinge axis of rotation when the collapsible chair is not rolled up;a second adjustment strap connected to a second corner of the base distal to the axis and connected to a second corner of the back distal to the axis, wherein the second corners of the base and back distal to the hinge are configured to support the base on a second adjustment strap plane perpendicular to the hinge axis of rotation when the collapsible chair is not rolled up and when the first and second adjustment strap planes are parallel;a top strap comprising a top strap fastening device, which top strap fastening device may be used to releasably attach the collapsible chair to a luggage;a side strap comprising a side strap fastening device, which side strap may releasably encircle the luggage;a first closure along a first perimeter of the base between the first corner of the base distal to the hinge and the first hinge end, along a second perimeter of the back between the first corner of the back distal to the hinge and the first hinge end, along a third perimeter of the base between the first corner of the base distal to the hinge to a middle of a side of the base distal to the hinge, and along a fourth perimeter of the back between the first corner of the back distal to the hinge to a middle of a side of the back distal to the hinge; anda second closure along a fifth perimeter of the base between the second corner of the base distal to the hinge and the second hinge end, along a sixth perimeter of the back between the second corner of the back distal to the hinge and the second hinge end, along a seventh perimeter of the base between the second corner of the base distal to the hinge to the middle of the side of the base distal to the hinge, and along an eighth perimeter of the back between the second corner of the back distal to the hinge to the middle of the side of the back distal to the hinge, wherein the first and second closures may close at least one set of corresponding perimeters of the base and back together, and wherein the collapsible chair is configured as a handbag.
