Hi Aileen! Unfortunately, I don’t think there are any specific products on the market that are made for benches. However, I would recommend looking for a booster that has safety straps. You could hopefully use one of the straps to go around the bottom of the bench. Look for non-skid bottoms and buckles so your little doesn’t slide out. Hope that helps!

Hi Charli! What about purchasing a cheap folding chair specific for use with your toddler and their booster seat. It will protect your antique chairs and be big enough for modern booster seats. If that’s not a possibility, make sure to get a booster that can be strapped down below the seat and around the back of the chair. That should ensure no tip overs. Hopefully that helps!

Sonia — I wouldn’t think you’d have a problem with upholstery, but I suppose it would depend on the exact fit with the chair… I think you’d *likely still have a good fit! Good luck!
