- Sizing Options: Available in Full Size, Midsize, and Petite to accommodate different body frames and shoulder widths.
- Firmness Variants: Comes in “Standard Firm” How exactly to beat the fake tracking number scam? and a “Gentle” version (which contains approximately 20% less fiber for a softer feel).
