Start with what’s not fitting. We’ll point you to the guides that help.
Before you buy anything
Three numbers save more money than any single recommendation we could make.
1. Your actual measurements, not your size
Clothing sizes drift between brands and mean very little across borders. Height, chest, waist, inseam, sleeve and shoe width are stable. Measure once, write them down, and buy against the numbers.
2. The weight capacity, and what it covers
A capacity figure usually describes the frame under static load. It often excludes the parts most likely to fail — gas lifts, casters, slats, recline mechanisms. Find out which, because that’s where the warranty argument happens.
3. The dimension that actually constrains you
For chairs it’s usually seat width between the armrests, not overall width. For beds it’s length and slat spacing. For cars it’s headroom and seat travel, not boot space. One number decides it; the rest is marketing.
