Thank-you Violet and Sam for posting what works for you as a meditation space. I agree with both of you, the meditation space does not have to be specific, it just needs to meet our needs as a contemplative.
When I was a householder, I had a room that was set aside only for meditation yoga, like Violet's. It was the rear room at the center of the house so that it was the quietest room in the house. Additionally I rented a house that was on the edge of town, in a quiet, rural neighborhood, and nature trails were right outside.
At that time I worked out of my home, so that when my children were at school, then the whole house was quiet, so that I could meditate at any time, when I was not occupied with serving a customer, who were few and far between.
Now that I live in a van, then, like Sam, my bed is my meditation place. I prefer to sit cross legged, but I have in the past used a meditation bench, like Violet.
I prefer to meditate in nature now, so when I have a chance, which I often do, I camp in the wilderness and there I find the most conducive environment for meditation.
However, I once lived in an apartment in San Francisco. There I found an apartment in the center of a quiet neighborhood, where I had a room that was in the center of the apartment, and it was dedicated to meditation and yoga.
