Start with evidence

Research the exact mattress by name.

Construction, policies, independent findings, owner patterns, and missing evidence kept separate, so you can make a more informed choice.

The matcher

Three questions. One shortlist.

How you sleep, side, back, stomach, or a mix.

Your build, under 130 lb, 130–230 lb, over 230 lb.

What hurts, pressure, heat, motion, edges.

Matched against the same evidence records you can read yourself.

How we work

We show the evidence, including the gaps.

We document products and policies, and we do not pretend to have slept on mattresses we have not physically tested.
