Our original 12-inch AmazonBasics mattress had a softer feel than many similarly built budget foam beds. The reviewer, then around 200 pounds, found it supportive enough while noticing substantial cushioning. This is a historical test of a specific model; current Amazon-branded listings may use different materials and firmness.
What we tested
Yawnder purchased and reviewed the 12-inch AmazonBasics memory-foam mattress. Our reviewer found it on the softer side compared with several other three-layer foam beds. Thinner versions were available at the time, but this review’s findings do not establish how those versions feel or perform.
The mattress may appeal to someone who likes to sink into foam. A sleeper who prefers a firm surface, or who compresses the comfort layers more deeply, should compare alternatives and the seller’s return terms.
Original construction
The tested mattress used memory foam over two sculpted support-foam layers. The original description included ventilation holes and contoured surfaces intended to encourage airflow. These design features do not prove a particular overnight temperature; room conditions, bedding and personal preference all affect heat.
Sinkage and motion
Our 14-pound bowling ball created noticeable compression, consistent with the soft surface observed in the original test. The reviewer found the foam absorbed movement better than a traditional spring mattress, though it was not the most motion-deadening foam bed tested. A bowling ball is a visual demonstration, not a standardized measurement of how every sleeper will feel.

What to check if buying today
Amazon has listed multiple mattresses under its own branding, including models with different thicknesses and stated firmness. Confirm the exact model, dimensions, construction, seller, condition and return terms rather than assuming the current listing is the same as our sample. Compare the complete delivered price and the foundation requirements.
