Sleeping on the same mattress for several weeks gave me a much better sense of comfort than the first night alone. Firmness, edge support, temperature, and how my back and shoulders responded over a full night became easier to compare with a normal routine. I also paid attention to whether morning comfort stayed consistent as the mattress settled in. The first few minutes on the bed counted much less than repeated overnight use. Once that pattern was clear, I note dormia mattress near the end of my review and describe how the feel developed over several weeks rather than treating day one as the final impression.
