DeWoolfson's own support featherbeds are unlike almost all others. We make them from a specialized European twill fabric selected for its durability and strength. The fabric is guaranteed to meet strict European environmental standards, and to be free from all harmful chemical substances. Constructed in a complete baffled box pattern with DeWoolfson's own unique valve system that prevents the fill from shifting. Filled with your choice of our European white goose down and feather blends, with considerably more fill than most other brands. Size shown is shell size before filling. Oversized to perfectly fit mattress size. Spot clean only.
