How sleep is built
A good place to sleep lets the night be forgotten.
Carry first
A solid frame holds the mattress and the body without collapse. When support fails, comfort scatters with it.
Then the surface
Shoulder and hip need a little descent. Too much leaves the morning heavy. Too little cuts a side sleeper short.
A way out for heat
Breathable fabrics and open builds give the air a path.
Size and the house
The bed sits in the room you already have. 160 or 180 is not only a number. It is the distance between two people.
Choosing a model is not reading a chart. It is imagining a night together.
