This is a review of the B540 Compass Ultra Adjustable Folding Booster made by First Years/Learning Curve.
The B540 model is very similar to the B530 (they actually share the same instruction manual) but there are a few notable differences.
- B540 has more padding built into the cover
- B540 headwings are 2″ deeper for better SIP and sleep support
- B540 has EPP foam lining the headrest (B530 has EPS). Both EPP and EPS foam are energy absorbing materials but EPP is more durable and is less likely to crack under normal wear and tear conditions.
