I installed a couple of these in my kitchen. It might be a good solution for you in the dining room. I also have 3 ikea high chairs that fit perfectly underneath. It's been on of the best ikea purchases we've made so far.

I can only have a max of 3 children under 2, and 5 in total under the age of 6. I knew that I wanted little ones, because they're my favourite. So I took the max number of 1 year olds I could find. Now most of my kids are two year olds, and that is interesting.
