A used Special Tomato soft sitter with a base for sale. It was once bought in November of 2015 for my nephew, who no longer fits in it. The chair is for children 2 to 6 years old. The soft chair is easy to take away from the base, just unbuckle strap and pull from the base. The base has two large Velcro tapes to it, to lend a hand keep the chair from moving. The harness at the sitter is easy to take away, making the harness easy to put within the washing machine. I used disinfectant wipes to scrub the chair and base. I recently washed the straps of the sitter as well. The sitter itself is antimicrobial. Also, since the sitter is removable from the base, you’ll buy accessories to put the sitter on, such as a car seat, large push chair, and so forth.
