Quick Pick
Purple Original Mattress (Check it out)
The standout alternative with superior pressure relief via its GelFlex Grid, temperature regulation, and responsive feel at a competitive price. Perfect if you're eyeing the AS3 but want more innovation.
Getting a good night's sleep starts with the right mattress, and medium firmness hybrids like the Amerisleep AS3 (around 5/10 on the firmness scale) strike a balance for many sleepers.
