The Original is Casper’s OG and bestselling mattress — and for a good reason. From its deepest layers, this mattress is designed for a good night’s sleep. It features a comfy knit cover, the brand’s breathable foam, and a layer of pressure-relieving memory foam. The Original comes in two comfort levels: Original Foam (a medium-firm consistency) and Original Hybrid (a blend of foam and springs). Sadly, the Hybrid is not included in this sale, but the Foam is customers’ preferred choice with its supportive and firm bottom foam layer (as opposed to the Hybrid’s inner springs). As for logistics, it ships for free and quickly within one to two days with free returns and a 10-year warranty.
