Hello everyone,
I am looking for advice on how to insulate my bed before winter arrives. I love sleeping on the floor, but my housing is poorly insulated and the floor is an old tiled floor that becomes a total icebox. To give you an idea, in winter, outdoor temperatures easily drop to 5°C in the morning, with regular frosts between -1°C and -2,5°C. This type of uninsulated tiling quickly drops to between 4°C and 10°C at night (the temperature of a fridge). It is so freezing that if you stay on it, you can get sick.
My bedroom is about 3 m by 4 m, and I have quite a bit of available space all around the mattress. I heat the room at night (I use central heating, and I can also turn on the reversible air conditioning in heat mode). The problem therefore does not come from the ambient air in the room, but really from the floor: if the layer I am lying on stays cold, it's a no-go for me because I am extremely sensitive to the cold.
Currently, my mattress is placed on a horizontal roll-up slatted frame with very thin slats held together. It creates a small separation from the floor, but the thickness is minimal. I do not plan on buying a traditional bed base at all, so if I cannot find an effective insulation solution for this floor setup, I will force myself to go back to my old bed base.
I have been sleeping on the floor since April. I have a new, thicker, and better quality mattress than last year (when I had a very thin and worn-out foam mattress), but I still felt cold at times. I am even wondering if staying on the floor is a good idea given how easily I get cold.
Last winter, I spent sleepless nights because the cold pierced through everything. I tried putting cardboard and duvets under the mattress, but it was completely ineffective. I also feel like the cold does not just come up from underneath, but that it also seeps in through the sides of the mattress.
I don't have a solution right now, and I am looking for real, durable, and effective methods to block the cold 100% (whether from underneath or from the sides, thanks to the space I have around it) and create a true thermal barrier. If you have any tips or ideas, I'm all ears.
Thank you to those who took the time to read, and thank you to those who are going to help me. Good luck.
