B&M Mattress Review

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.

If you like a traditional innerspring with orthopedic positioning, look at Posturest Orthopedic Innerspring. If you want a conforming feel, choose Posturest Memory Foam. If you want resilient latex with pressure-point relief, choose Posturest Natural Latex.

Choose Custom-Sized for antique, RV or boat fits. Choose Adjustable Beds for head and foot elevation and massage. Firmness, sleeping-position and body-weight guidance aren't published (checked September 2026).

Prices aren't published (checked September 2026). The archived B&M homepage claimed factory-direct with no middlemen or retail-store markups. It also said every mattress was manufactured fresh when ordered.

We found no price grid, sizes, financing or value comparison. For current pricing, you should contact the successor, Cantwell Mattress, directly.

Per the archived B&M homepage, Posturest Memory Foam uses NASA-developed foam for orthopedically correct support. Posturest Natural Latex uses natural latex. Posturest Orthopedic Innerspring uses an innerspring for orthopedically correct support. Custom-Sized is for antique beds, RVs and boats, and Adjustable Beds come with a massage unit.

Full layer stacks, densities, coil counts, covers and certifications such as CertiPUR-US or GOTS aren't published (checked September 2026).

The brand doesn't publish durability, sag resistance, edge support, cooling, motion isolation or expected lifespan (checked September 2026).

The archived site said each sleep set was manufactured fresh when ordered. It also offered a Refurbish it option instead of sending an old mattress to the landfill. It published no years-of-use data, test results or durability ratings.

We couldn't find customer ratings, review counts or complaint summaries (checked September 2026). We found no verifiable B&M Mattress reviews, BBB profile, Yelp ratings or testimonial pages. The archived site invited walk-in customers but showed no reviews.

You should treat Cantwell Mattress reviews separately, and verify in store.

The historic address, per the archived homepage, is 4915 McCullough Ave, San Antonio, TX 78212. The phones were 210-824-0201 and 800-680-2337, and walk-in customers were welcome. The brand announced it joined the Cantwell Mattress family, with a combined showroom at the same McCullough address.

Current B&M availability isn't published (checked September 2026). You'll want to contact Cantwell Mattress at 4915 McCullough Ave or 6728 San Pedro, San Antonio, TX, to confirm.

The brand doesn't publish delivery areas, shipping costs, setup or old-mattress removal terms (checked September 2026). The archived site promoted made-to-order manufacturing and a refurbish option.

It listed no delivery zones, fees, timelines or haul-away policy. You should confirm with Cantwell Mattress directly.

The brand doesn't publish a sleep trial length, returns, exchanges, fees or refund terms (checked September 2026). We found no B&M trial or return policy in the archived homepage image or on the live domain.

Confirm any comfort guarantee with Cantwell Mattress before you buy.

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.

The successor, Cantwell, advertises a 365-day comfort guarantee on select two-sided models and an in-house power-base warranty. That applies to Cantwell, and we haven't verified it for older B&M units.

Against Cantwell Mattress, B&M announced it joined the Cantwell family in South Texas and shared 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.

Against national innerspring brands, B&M was local, factory-direct and focused on custom sizes. It wasn't a national bed-in-a-box brand. Detailed spec-to-spec comparisons aren't published (checked September 2026).

We read the brand's own product, policy and warranty pages, then checked retailer listings and public complaint sites like the Better Business Bureau. We last checked everything here in September 2026. Prices and policies change, so confirm them on the seller's page before you buy. You can read more in our methodology and editorial policy.
