Product trolleys include a base, a sling assembly, and a roller assembly. The base includes a first sidewall, a second sidewall opposing the first sidewall, and an endwall extending between the first and second sidewalls. The base defines an inner surface, a first open end, a second open end opposite the first open end, and a top opening opposite the endwall. The base includes a spring action between the first sidewall and the second sidewall, such that the base is configured to be flexed to receive and releasably secure the product between the first and the second sidewalls. The sling assembly is secured to the base and includes a substantially flexible body formed of sheet material. The roller assembly is secured to the base proximate the endwall.

What is claimed is: 1. A product trolley comprising: a base including a first sidewall, a second sidewall opposing the first sidewall, and an endwall extending between the first and second sidewalls, the base defining an inner surface, a first open end, a second open end opposite the first open end
What is claimed is: 1. A product trolley comprising: a base including a first sidewall, a second sidewall opposing the first sidewall, and an endwall extending between the first and second sidewalls, the base defining an inner surface, a first open end, a second open end opposite the first open end, and a top opening opposite the endwall; a sling assembly secured to the base, the sling assembly including a body extendable along a back of a product; and a roller assembly secured to the base proximate to a transition between the first sidewall and the end the endwall; wherein the base includes a spring action between the first sidewall and the second sidewall, such that the base is configured to be flexed to receive and releasably secure the product between the first and the second sidewalls, and wherein the base includes a support surface proximate to a transition between the second sidewall and the endwall, the support surface defining a lowermost extension of the endwall that is cooperable with the roller assembly to support the product trolley on a substantially horizontal surface. 2. The product trolley of claim 1, wherein the body of the sling assembly is substantially continuously formed as a single piece and is foldable into the base of the product trolley to transition the product trolley to a compact state. 3. The product trolley of claim 1, wherein the first sidewall extends to a terminal end, the first sidewall extending toward the second sidewall at the terminal end. 4. The product trolley of claim 1, wherein the second sidewall forms a grip projection extending from the inner surface of the base toward the first sidewall, the grip projection formed widthwise along the second sidewall. 5. The product trolley of claim 4, wherein the first sidewall extends to a terminal end, and further wherein the terminal end of the first sidewall and the grip projection of the second sidewall are positioned such that the terminal end is laterally opposed to the grip projection. 6. The product trolley of claim 1, wherein the endwall forms a toe portion proximate the first sidewall and a heel portion proximate the second sidewall, wherein the toe portion protrudes distally opposite the top opening more than the heel portion projects distally opposite the top opening. 7. The product trolley of claim 1, wherein the body of the sling assembly defines an upper portion and a lower portion, wherein the upper portion has an opening adapted to receive a hand, wherein the lower portion of the body is secured to the base. 8. The product trolley of claim 7, wherein the body of the sling assembly defines a first side and a second side, the first side opposing the second side, and further wherein the sling assembly further comprises: a first strap connected to the first side of the body and a second strap connected to the second side of the body, each of the first and second straps being substantially flexible and adapted to be wrapped about the product; wherein at least one of the first and second straps includes a connector for securing the first strap to the second strap. 9. The product trolley of claim 1, wherein the roller assembly comprises: an axle guide having an inner lumen extending through the axle guide, the axle guide projecting from the base; an axle coaxially received in the axle guide, the axle defining a first end and a second end; a first wheel secured to the first end of the axle; and a second wheel secured to the second end of the axle. 10. The product trolley of claim 9, wherein the first sidewall, the second sidewall, the endwall, and the axle guide are substantially continuously formed as a single piece. 11. The product trolley of claim 1, wherein the endwall of the base defines a thickness, wherein the endwall has a handle opening sized to receive a hand, and further wherein the handle opening is formed through the thickness of the endwall. 12. The product trolley of claim 1, further comprising a support projection substantially extending across a width of the base and disposed adjacent the support surface, the support projection adding stability to the base and cooperatively supporting the product trolley with the support surface.
