I feel comfortable question

On my former old just plush pillow top mattress, sometimes I feel cold when I was sleeping.
On my brand new ultra plush pillow top high 17.5 mattress, I feel really comfortable temperature when i was sleeping, i don’t feel hot or cold, is it just me or it just my brand new mattress?

With all else being equal, a more plush mattress will allow you to sink a bit further into the mattress which can result in you sleeping warmer. As your body is more deeply enveloped in the comfort layers of the mattress it can feel relatively warmer since air flow is more limited and your body heat is captured.


Oh ok I know now. Thank you for reply
