5. Operating Modes (6 Stages of Use)
The Graco DuoDiner DLX Highchair offers exceptional versatility with six distinct modes to accommodate your child's growth:
- Infant Highchair: Designed for newborns and young infants, this stage utilizes the plush infant body support and offers 3 recline positions for comfortable feeding or resting.
- Traditional Highchair: For babies ready to sit upright and begin solid foods. The soft fabrics and cozy, machine washable seat pad provide a comfortable and secure environment.

- Toddler Booster: As your child grows, the booster can be used without the infant insert, providing a perfect elevated seat for toddlers at the table, suitable for home or travel.
- Youth Stool: The highchair frame converts into an elevated youth stool, offering a dedicated seat for older children at the dining table or counter.
- Seating Two Kids at Once: This unique feature allows the highchair (Stage 2) and the Youth Stool (Stage 5) to be used simultaneously, providing independent seating for two children.
6. Adjustments
The DuoDiner DLX offers multiple adjustment options for optimal comfort and fit:
- Recline Positions: The seat offers 3 recline positions, ideal for infants who need more support or for comfortable bottle feeding. Adjust by pressing the recline buttons on the sides of the seat.
- Height Positions: With 5 adjustable height positions, the highchair can be easily positioned to match various dining table heights, ensuring your child is always at the right level for family meals. Adjust by pressing the height adjustment buttons on the side of the frame.
- Adjustable Footrest: The footrest can be set to 3 different positions to provide proper support for your child's feet as they grow.
