Marcella, where did you get your knee stand? I assume it’s a foamy sort of base that you kneel on with two rails that you can hold on to to get yourself up?
It's the best thing since sliced bread. It's stationed right now in front of my TV set and it's hardly noticeable. It just ended up there but that's not where I'll have it. It is hard metal that comes up on both sides with two soft enough cushions. You use it two ways. Put it with the cushions next to the floor and you can easily kneel holding onto the two sides. Getting up using the sides is totally easy.
Then, you can turn it over, which gives you two long sides on the floor and a raised seat. Ordered it from Walmart $28.53 and worth every penny.
