About
A measurement atlas, not a mattress review site
Bed Size Lab separates local labels from the dimensions that actually determine fit.
What we publish
Source-backed adult bed, mattress, bedding, and pillow dimensions; proportional diagrams; conversion and fit calculators; and transparent uncertainty notes.
What we do not publish
We do not publish infant or child sleep guidance, medical or therapeutic advice, ergonomic claims, firmness recommendations, fire-safety or weight-capacity claims, code or accessibility determinations, or untested “best” rankings.
