DIY Yuba Mundo Soft Spot Seat

Posted on Updated on

My husband gifted me with a brand new Yuba Mundo cargo bike last week. I love it. My three boys can all ride on it and they are asking daily to go for a bike ride. I plan to get a child seat for my middle son, but for my oldest, I plan for him to sit directly behind me on a seat pad. He will also have stoker bars that are attached to my seat post for him to hold on to. I’m a DIY kind of gal and new I had the materials on hand to make a similar style seat pad that Yuba offers on their website called a Soft Spot.

I unpacked my sewing machine yet again, (we are moving this weekend but I can’t seem to go a week without needing my sewing machine).

Materials used:

Old pink yoga mat
Thin green foam padding
Handprint oil cloth
Gutterman Thread.

I measured off the amount of padding I needed for the seat by laying the yoga mat onto the bike. I cut the yoga mat twice as wide as I needed so I could fold it over, sandwiching the thin green foam padding in a single layer between.



I laid this padding on top of the oil cloth and cut it with about a 0.5 ” to .75 inch seam allowance all around, and cut it lengthwise twice as long. I folded the fabric right sides together, placing five pieces of Velcro around the edging, making sure to sandwich it between the fabric. I sewed around the edges, leaving one side open so that I could stuff the two layers of yoga mat with the thin foam between. The Velcro proved a bit tricky because I didn’t think about how I wanted to attach the Velcro to itself properly. I ended up ripping out stitches and made sure that the Velcro was not sticking to itself when I stitched it in.


Before turning the sleeve of fabric inside out, I clipped the corners so that when I turned it inside out, the corners would look better. I stuffed the foam and yoga mat inside the sleeve and stitched the open end closed. It fits perfectly on the Yuba, now I just need to get more Velcro to make another one for my middle son until I can purchase a real seat for him.

    Just what I’ve been looking for! We recently got a Kona MinUte and I was thinking I should be able to make a seatpad rather than ordering the Yuba Soft Spot. Thanks for the instructions! How is it working for you? Is the velcro strong enough to hold it securely in place? I was trying to decide if I had to make it more complicated and sew in buckles to webbing straps…

      The seat pad has been doing really well staying in place. Only complaint from the five year old that his legs were hurting on the sides. Since we got a peapod for the back, I had an extra pad, so I crossed it over the top of other one and velcroed it down.

      I would mess with buckles, as long as you make the Velcro long enough, you can curl it around itself.

        Thanks again very much for the idea to use yoga padding! I made a version of this on the weekend and my son loved how much more comfortable it was than the wooden deck :).
