How We Verify Specs
Every bed in the database carries a source URL and a check date. The specs in our tables were read from that page on that date. That is the whole method, and it is stricter than it sounds: no spec enters the database from a review roundup, a retailer listing or memory.
What the dash means
When a manufacturer does not publish a number, the table shows a dash. We do not estimate, interpolate or copy a figure from a third party. A dash is an honest answer. If a spec matters to your decision and the row shows a dash, ask the manufacturer before buying, or check the source link on the bed's page in case they have since published it.
Check dates
Manufacturers change specs, prices and warranties without notice. The check date on each bed's page tells you how fresh our reading is. We re-verify on a rolling basis and the date only changes when a human actually re-reads the source.
Commercial and editorial claims never merge
If a bed is ever promoted for commercial reasons it will be labeled as such. That label will never imply its specs were verified more deeply than others. A spec source and check date cannot be bought.
How complete the database currently is
Method is easy to claim, so here is the result of ours. Across 73 models from 10 makers we look for 934 individual figures and the manufacturers publish 618 of them, which is 66%. The missing 316 are shown as dashes rather than filled in, and we would rather publish an uncomfortable completeness figure than a tidy table with invented numbers in it.
The figures manufacturers withhold most often, and how many models each is missing on:
- assembly time, absent on 65 of 73 models.
- the mattress weight window, absent on 54 of 73 models.
- maximum mattress thickness, absent on 30 of 73 models.
- panel materials, absent on 29 of 73 models.
Where it gets difficult
Three situations come up repeatedly and each has a fixed rule. When a maker publishes a dimension only inside a drawing or a photograph, we leave it blank rather than measuring the image, because a number read off a picture is a guess wearing a lab coat. When a spec sheet gives shipping carton dimensions but not assembled ones, we do not substitute the carton, since a carton is not a cabinet. And when the same page states a figure twice with a small discrepancy, we take the primary specification table and note the conflict on the record rather than silently picking one.
Prices get the same treatment and need the most caution from you. This category runs near permanent promotions, so a price here is what the manufacturer showed on the check date, not a quote and not today's number. Where a model sells only through dealers we publish no price at all rather than a range we cannot source.
What we are not
We have not slept on these beds, taken one apart, or run a mechanism to failure. Nobody publishing at this scale has, and a site that implies otherwise is telling you something it cannot know. What this database does is put every maker's own published figures in one place, in the same units, with the gaps visible. That is a narrower claim than a review site makes and it is one we can actually stand behind on every row.
