A Hawaii-based mattress retailer is pitching a body-scanning tool that promises to take the guesswork out of buying a bed.

• BedMart, a family-owned Hawaii chain running since 1992, is promoting an in-store tool called SmartMatch.
• The tool takes 18 body measurements and factors in lifestyle, then narrows its 50 showroom mattresses down to the ones that fit you.
• The scan takes about three minutes, after which a sales consultant walks you through the matching options.
• The pitch: mattress shopping doesn't have to be high-pressure or confusing, and most people wait too long to replace an old bed.

Outlook: Expect BedMart to keep leaning on SmartMatch as its main draw across its Hawaii stores and website.
