3DTMT Seat Cushion
About this project
A soft, removable seat cushion + cover designed specifically for the 3DTMT: 3D-Printed Toddler Mobility Trainer. This updated cover design features a fold-over construction, making removal for washing easy.
The challenge
Many young children who use early-mobility devices benefit from improved stability, pressure distribution, and gentle postural support. A dedicated cushion helps reduce fatigue, increase comfort, and encourage longer, more engaged use of the device.
Who it helps
Toddlers and young children who use the 3DTMT, particularly those with limited core strength, mobility challenges, or conditions that make prolonged sitting uncomfortable without added support.
How it works
This Product is compatible with the 3D-Printed Toddler Mobility Trainer.

The cushion adds comfort and light postural support, reducing pressure points so children can sit upright and use the device for longer. Its removable, washable design makes it easy to maintain in home or clinical settings.
