Our take on the Isotonic Indulgence Down Alternative Side Sleeper Pillow

The Isotonic Indulgence is a down-alternative side sleeper pillow filled with synthetic down fiber meant to mimic European goose down. It has a medium firmness, a removable 500-thread-count cotton cover and an antimicrobial-treated inner cover, and it is machine-washable. It suits side sleepers who want a soft, hypoallergenic pillow and prefer to avoid real down. Owners are split: many long-time buyers find it comfortable and free of neck pain, but a number of recent buyers say it flattens under the head and loses loft faster than earlier versions.
