Yes, high chairs and booster seats can be used for travel, but their suitability depends on several factors. 
High chairs are generally bulkier and less portable, making them less ideal for travel unless they are specifically designed to be compact and foldable. Travel high chairs are available that are lightweight, easy to fold, and can be attached to tables or chairs, making them convenient for use in restaurants or hotels.
Booster seats, on the other hand, are more travel-friendly due to their compact size and lightweight nature. They are designed to be easily portable and can be used in various settings, such as cars, airplanes, or dining establishments. Some booster seats are inflatable or collapsible, further enhancing their portability.
When choosing a high chair or booster seat for travel, consider the following:
1. **Portability**: Look for models that are lightweight, foldable, or inflatable for easy transport.
2. **Ease of Use**: Ensure the seat is easy to set up and secure, especially in unfamiliar environments.
3. **Safety**: Check for safety features like secure straps and non-slip bases to ensure the child's safety.
4. **Versatility**: Some booster seats can double as car seats, providing added convenience for travel.
5. **Durability**: Choose materials that can withstand frequent use and are easy to clean.
In summary, while traditional high chairs are not ideal for travel, travel-specific high chairs and booster seats offer practical solutions for feeding and seating children on the go.
