AmazonBasics Memory Foam Mattress Review: Original 12-Inch Testing Restored
The AmazonBasics page had lost the specific 12-inch hands-on review that originally made it useful.
What we bought
Yawnder purchased/reviewed the 12-inch AmazonBasics memory-foam mattress rather than the thinner 8- or 10-inch versions.
Soft feel
Among similarly constructed three-layer foam mattresses, the 12-inch AmazonBasics skewed soft. At around 200 pounds, the reviewer still felt adequately supported, but cautioned that the thinner versions would likely feel less substantial for heavier sleepers.
Three-layer construction
The mattress used memory foam over two convoluted support layers, with ventilation holes and sculpted surfaces intended to increase airflow.
Sinkage
Our 14-pound bowling ball produced substantial compression, consistent with the softer feel.
Motion transfer
The foam construction controlled movement far better than a traditional spring mattress, although the lower-density feel meant it was not the most motion-deadening foam bed we had tested.
Current-shopping note
AmazonBasics/Amazon-branded mattress SKUs change frequently and may not be sold in the same configuration. Use this as a historical review of the 12-inch model.
