Buying Guide: Key Purchase Considerations
- Safety standards and materials: Look for CPSIA/ASTM compliance and non-toxic, odor-free foam. Soft surfaces with rounded edges reduce injury risk for toddlers.
- Block counts and shapes: Sets vary from 4-piece to 138-piece packs. Consider your child’s age, space, and desired complexity. A mix of cubes, stairs, arches, and rectangles expands creative options.
