Common options include built-in pet caves or nests integrated into the footboard and oversized human-and-pet loungers with bolstered sides designed for co-napping.
Frames and platforms are often polyester or plywood; upholstery commonly uses velvet, faux fur, or other textile fabrics; and internal support is provided by various foam types.
Shared loungers typically use bolstered walls with foam cores such as eggshell memory foam, orthopedic foam, or high-density foam to provide pressure relief and structural support.
Most require adult assembly (tools may be provided or required), and platform designs generally do not require a box spring.
Some models include silicone-grip or embedded silicone-particle bases and non-slip PVC bases to help anchor the bed on hard floors or carpet.
