At my previous school, I had to deal with the same situation you are in David. For student work tables I decided to go with 18" metal stools (standard science lab model) and 40" high tabletops. The tabletops were 2" butcher block, 30" x 60", steel frame, and on lockable casters. Like Tracy mentioned, stools were optimal (especially in our small classroom foot print) since they could fit under the tables all the way when not used. Or be stacked. Students often stand up when using tools and working on construction projects. I found the dimensions worked were just fine for MS. The 18" stools worked for LS but the 40" table height was challenging for using some of the tools (saws and drills) since kids are too short to get the proper leverage. But we all coped. LS can also use the stool seat to saw/drill on. The 18"/40" is poor laptop ergonomics but it was the best we could do. Adjustable height sounds good but it either compromises the sturdiness of the table or can be a serious chore, sometimes a 2-person job, to adjust. For daily transitions back and forth between LS and MS I knew I would not adjust them.
A makerspace (like any classroom) shouldn't have to accommodate that large of an age span, but we were stuck with the limitation of space. Sounds like you are in a similar situation. I only hosted classes for grades 1-8. Even if I had to teach K classes I would have insisted tech/make class happen in the K classroom. The equipment and furniture in the Lab would not have worked for K in my opinion.
The school worked with One Workplace in SF who contracted the tables from a small shop in Morgan Hill. If you are looking for similar work tables, I could probably track down the contractor name.
