A leg assembly includes four legs, each of the legs configured to couple to an outer edge of a generally planar member to form an assembly that has a surface supported by the four legs. The leg assembly also includes an adjustable strap coupled to and extending between two of the four legs to form a bracing structure to provide enhanced structural rigidity for the assembly for attachment to a planar element includes four legs.

1. A leg assembly comprising: a generally planar member including a top surface and a bottom surface;four legs, each of the legs including an upper plate coupled to the top surface and a lower plate coupled to the bottom surface, wherein each leg receives a corner of the generally planar member between the upper plate and the lower plate to couple the generally planar to each of the legs; anda first adjustable strap coupled to and extending between two of the four legs that are diagonally-opposed to each other to form a bracing structure to provide enhanced structural rigidity for the assembly; anda second adjustable strap coupled to and extending between the other two of the four legs that are diagonally-opposed to each other;wherein each of the first adjustable strap and the second adjustable strap each include a strap portion and a tightening member for adjusting a tension of the strap portion to hold the associated legs against the generally planar member; andwherein the strap portion and the tightening member do not contact, and are not coupled to, the generally planar member. 2. The leg assembly of claim 1, wherein the upper plate is substantially coplanar with the lower plate. 3. The leg assembly of claim 1, further comprising a thumbscrew threadably coupled to the lower plate, wherein the thumbscrew couples the generally planar member to the leg by clamping the corner of the generally planar member between the upper plate and the lower plate. 4. The leg assembly of claim 3, wherein the thumbscrew includes a threaded portion threadably coupled to the lower plate and a flat member disposed at a top end thereof between the upper and lower plates, and wherein the flat member engages the bottom surface of the generally planar member by adjusting the thumbscrew so as to clamp the corner of the generally planar member between the upper plate and the flat member. 5. The leg assembly of claim 1, wherein each leg has a generally L-shaped cross-section that defines two perpendicular sides, and the cross-section of the legs engages the corner of the generally planar member. 6. The leg assembly of claim 5, wherein each side of the cross-section of each leg includes an elongated opening for receiving a portion of the adjustable strap to secure the two legs together. 7. A leg assembly comprising: a generally planar member including a top surface and a bottom surface;four legs, each of the legs including an upper plate coupled to the top surface and a lower plate coupled to the bottom surface, wherein each leg receives a corner of the generally planar member between the upper plate and the lower plate to couple the generally planar to each of the legs; andan adjustable strap coupled to and extending between two of the four legs to form a bracing structure to provide enhanced structural rigidity for the assembly;wherein the adjustable strap includes a strap portion and a tightening member for adjusting a tension of the strap portion to hold the two legs against the generally planar member;wherein the strap portion and the tightening member do not contact, and are not coupled to, the generally planar member; andwherein the adjustable strap is coupled directly to the legs without any intermediate member. 8. A table comprising: a tabletop including a top surface and a bottom surface;four legs coupled to the tabletop, each of the four legs including an upper plate coupled to the top surface and a lower plate coupled to the bottom surface; andat least one adjustable strap extending between and coupling a plurality of the legs to each other to resist outward movement of the legs relative to the tabletop to provide enhanced structural rigidity for the table;wherein the adjustable strap includes a strap portion and a tightening member for adjusting a tension of the strap portion to hold the plurality of the legs against the tabletop;wherein the strap portion and the tightening member do not contact, and are not coupled to, the generally planar member; andwherein the adjustable strap extends between two of the four legs that are diagonally-opposed to each other. 9. The table of claim 8, wherein the upper plate is substantially coplanar with the lower plate. 10. The table of claim 8, further comprising a thumbscrew threadably coupled to the lower plate, wherein the thumbscrew couples the tabletop to the leg by clamping the tabletop between the upper plate and the lower plate. 11. The table of claim 10, wherein the thumbscrew includes a threaded portion threadably coupled to the lower plate and a flat member disposed at a top end thereof between the upper and lower plates, and wherein the flat member engages the bottom surface of the tabletop by rotating the thumbscrew so as to clamp the tabletop between the upper plate and the flat member. 12. The table of claim 8, wherein each leg has a generally L-shaped cross-section that defines two perpendicular sides, and the cross-section of the legs engages a corner of the tabletop. 13. The table of claim 12, wherein each side of the cross-section of each leg includes an elongated opening for receiving a portion of an adjustable strap to secure the two legs together. 14. The table of claim 8, wherein the adjustable strap does not contact the tabletop. 15. A method of coupling a plurality of legs to a tabletop, the method comprising: inserting a first corner of the tabletop between a first upper plate and a first lower plate of a first leg;inserting a second corner of the tabletop between a second upper plate and a second lower plate of a second leg, the second corner located opposite the first corner; andbracing the first and second legs to the first and second corners, respectively, using a first adjustable strap extending between the first and second legs;wherein the adjustable strap includes a strap portion and a tightening member for adjusting a tension of the strap portion to hold the first and second legs against the tabletop;wherein the strap portion and the tightening member do not contact, and are not coupled to, the generally planar member; andwherein bracing the first and second legs to the first and second corners includes coupling the adjustable strap directly to the first and second legs without any intermediate member. 16. The method of claim 15, further comprising: clamping the first leg to the first corner of the tabletop between the first upper plate and the first lower plate using a first thumbscrew adjustably coupled to the first lower plate; andclamping the second leg to the second corner of the tabletop between the second upper plate and the second lower plate using a second thumbscrew adjustably coupled to the second lower plate. 17. The method of claim 15, wherein the first adjustable strap acts as a cross-brace between the first and second legs.
