B&M Mattress Co. was established in 1932 in San Antonio, Texas. It was a factory-direct maker of handcrafted Posturest innerspring, memory foam and latex mattresses, plus custom sizes. It later joined the Cantwell Mattress family at 4915 McCullough Ave. Its original website is offline as of September 2026. So you'll want to shop Cantwell directly. Call ahead to confirm what's available, since we found no current B&M listings.
Best for San Antonio-area shoppers who wanted factory-direct, made-to-order mattresses, custom sizes for antique beds, RVs and boats, and orthopedically correct support without retail markups; walk-in buyers welcomed. Not for online-only shoppers, as no current B&M e-commerce page was found; consider Cantwell Mattress instead.

Comfort and firmness: which mattress fits you
Why this matters to you: Feel names are the brand's words, not measurements. Use them to shortlist two or three beds, then let your body decide.
Choose Posturest Orthopedic Innerspring if you prefer traditional innerspring with orthopedic positioning; choose Posturest Memory Foam for conforming foam feel; choose Posturest Natural Latex for resilient latex with pressure-point relief; choose Custom-Sized for antique, RV or boat fits; choose Adjustable Beds for head/foot elevation and massage. Firmness, sleeping-position and body-weight guidance Not published as of Sept 2026.

Which B&M Mattress feel fits you?
Weight chart not yet researched
Weight and sleep position can change how a bed feels. We have not yet checked whether B&M Mattress publishes a fit chart by body weight, so use a trial, where one is offered, to test the bed the way you sleep at home.
Neck: on your side, your nose should line up with the middle of your chest, not tip up or down.
Shoulders: your bottom shoulder should sink in. Tingling or a numb arm means the bed is too firm for you.
Lower back: on your back, slide a flat hand under your waist. A big gap means too firm; no room at all can mean too soft.
Hips: ask someone to look from the side. Hips lower than shoulders means the bed is too soft for you.

What do the warranties cover?
Why this matters to you: A warranty is only as good as its terms. Read the written terms and use a supported base, because the wrong frame can end coverage.
The brand doesn't publish a warranty length, coverage, sag threshold, claim steps or exclusions (checked September 2026). We found no B&M warranty page.
Warranty length, coverage, sagging threshold, claims process and exclusions Not published as of Sept 2026. No B&M warranty page was located; successor Cantwell advertises a 365-day comfort guarantee on select two-sided models and in-house power-base warranty, which applies to Cantwell, not verified for legacy B&M units.

Strip the bed down to the mattress and wait a few hours so the top layers can recover.
Lay a straight edge (a broom handle or long level) across the dip, resting on the flat parts.

B&M Mattress vs. other mattress brands
Why this matters to you: A fair comparison needs the same facts for both beds. Line up price, trial and warranty for each one.
Vs. Cantwell Mattress: B&M announced it joined the Cantwell Mattress family in South Texas, sharing the 4915 McCullough Ave showroom; Cantwell now lists Sleep by Cantwell, Memory Foam, Latex Foam, Traditional Double-Sided, Never Flip Single-Sided and Custom models. Vs. national innerspring brands: B&M was local factory-direct and custom-size focused, not a national bed-in-box brand.
