Cushioning-type suspension packages are described that include (a) a product-supporting platform having first and second opposed faces; (b) two end panels, each pivotally connected to a respective end of the product-supporting platform; (c) two side panels, each pivotally connected to a respective side of the product-supporting platform; and (d) an elastomeric enclosure mounted between the two end panels and extending over the first face of the product-supporting platform. The two side panels are configured to pivot towards the first face of the product-supporting platform, such that the two side panels may be configured substantially perpendicular thereto. The two end panels are configured to pivot towards the second face of the product-supporting platform, thereby tensioning the elastomeric enclosure, such that acute angles may be formed between the second face of the product-supporting platform and each of the end panels. Retention-type suspension packages, suspension systems, cushioning panels, and methods of packaging products are also described.
