Yoga mat is about perfect for me IF sleeping on my back. Floor not bad. Bed is much better for sleeping on my side though. Absolutely hate sleeping cold though. Cold will wake me up every time.

Try sleeping in a hammock. It may be uncomfortable at first, but the body gets used to it, and may grow to prefer it. It provides maximum air circulation around the body during hot nights.

After my spinal damage from a crash, I can't lay on the hard floor any more. I have bones and muscles shift around in weird ways that seem to stay out of place. In many ways, my chronic issues are like someone that is much older than myself. You're likely to experience similar at some point much later in life, when your body physically needs that extra support to stay in one piece effectively.

Some natural cushioning is needed to appreciate the comfort of the floor, I imagine. I'm too boney for that.

Not really a temperature thing, but I also can't sleep shit on soft bed or I'll just get the worst sleep quality and everything hurts in the morning. I'm rather ligh-weight but I've always gone for the stiffest possible mattresses because it feels more comfy to sleep on.

And I love to sleep on those thin foam sleeping pads, just the best shit and you wake up so fresh

Guy, some of us have AC lol. And a firm mattress is far more comfortable unless you are way overweight.

Im on the edge but leaning toward upvoting. Sometimes the floor is great and temp is a big reason as well as sometimes the firmness but then there is just being with the dog or having my legs elevated on the couch. Its sorta fun to. All the same I really like my bed and would not want to give it up day to day.

Huh, nice timing. I'm laying on my floor typing this because my bed was too soft. I like the firmness of the floor sometimes.

I've discovered the wonders of a coconut husk mattress. It is hard with some give.

Fantastic for my back. Can't sleep on soft beds anymore.

Also I use a rolled up towel under my neck for support.

A tatami mat might work for you.

"Room temperature" is such an odd way to refer to a temperature.

It never drops below room temperature in a room. Because, you know, room temperature is the temperature of the room.

Agreed. Couches and cushions make poor posture, carpet collects dust, and most fabrics shed microplastic. Never be ashamed of your thirst for clean hard wood.

I love my bed. I do though sit on the floor in the lounge. I vary better the floor and the sofa. I find it comfortable.

I think it stemmed from when I was younger. My mum was quite obsessive with being tidy. To not mess up the sofa and cushions,.I'd just sit on the floor.

I live in the UK where generally our lounges are carpeted so it's not a solid floor. Our weather is typical crap though so it's due to being hot.

I have a shikibuton and a very expensive mattress. I vastly prefer my shikibuton and sleeping on the floor. It tends to be cooler as you say, and my cat comes and lays right next to me sometimes rather than on me. Plus the floor is more supportive than the mattress without being overbearing.
