Use long zip ties to make it easy to reach under the chair and thread the tie through the inner hold that you've just drilled.

In the chair I drilled two holes about an inch up from the bottom of the base. As the material is relatively soft, I used a couple of washers to give a bit of additional strength.

I used one hole and zip tie at the front.

Snip off the excess zip tie with wire cutters and you're good to go. To keep things clean, I had the zip tie ends meet underneath the base.

The finished product – works well and my grandson loves it. Of course, he needs a lot of support while he's in it as his upper body strength is also challenged by SMA – the main point of this was to provide him with another opportunity to expand his horizons. On that front, we certainly have success!

I have a 2 year old daughter who has spina bilfda and i am looking for a toddler wheel chair and i like to know prices on the wheel chairs.
Hi Lissette,
As I mentioned in my email to you, check out Bella’s Bumbas. This is a charitable organization and they provide toddler chairs similar to what I’ve built here, for the cost of shipping. It is an incredible organization.

Hi Rebecca,
Bella’s Bumbas is an incredible organization and I am proud to be able to share about it whenever I can. When I initially built this for my grandson, I went through a lot of online searching and in doing so discovered Bella’s Bumbas. I will try to contact you through your website.
