New to raised bed gardening, really raised!
Had some waist high wooden bins made so husband can continue to garden outside but not bend down. Depth to bottom is around 18”. Do we lay some inorganic matter in the bottom then soil, or all soil? How should we mix the soil, like bagged garden soil, a mix of some kind? Looking for suggestions on any/all aspects. Thanks

If the bins are sitting on concrete, brick, or blacktop you should fill them with a 50:50 mix of compost (Leafgro, mushroom compost, or the compost at the landfill are all good) and a soilless growing media. The latter contains some of the following ingredients: peat moss, coconut coir, pine fines, vermiculite, perlite.
If the bins are sitting on soil and roots can grow into the soil you can fill the bins with a 50:50 mix of compost and good topsoil from your yard or use commercial bagged topsoil.
You can remove the turf around the bins, turn it upside down and let the turf die completely and then add it to the bins. Then use wood chips for a walkway around the bins.
