I've had the best sleep for my spine on a single futon matress directly on the floor. If you look on craigslist you can often find people giving them away.

a real nice sealy bed that i scored out of my divorce

I have a quality thick futon mattress. My fiance thinks it's too hard so we've got a layer of memory foam on top to help him sleep better. But for me, the firm mattress is definitely the way to go.

There is a balance between firm support and comfy cushion that is healthy, but everyone finds comfort at different levels. You may want to try out different mattresses at hotels and see what type is best for you.

I son't know what a "KY yogi" is, so I'm not sure if I qualify to reply to your question.

My first trip to India, at the train stations, we'd sleep on a straw mat llike everybody else,...with maybe a sleep bag if it got cold. Yogis in the forest sleep on the forest floor. Sadhus sleep how they can.
Americans insist on their comforts. Many feel that conscious resting as opposed to deep slumber, is un-American. In the last 20 years, even the Army started to provide those isolation mats for bivouac....but I think there's still no law against sleeping au naturale... maybe even some yogic/meditational benefits.

Comfort kills? Luxurious furniture is the opposite of yoga?

Let Spirit guide you.... if the world will let you.

I have a sleep number bed. Expensive but worth very cent. Not very zen but if I don't sleep I'm not worth much.

When I first began yoga I had a lot of back work to do. Sleeping on the floor really helped me. I've slept on the floor now for over three years. I love the extra space it leaves in my bedroom. And now I actually get a back ache if I sleep in a bed.
