What customers say
The Amerisleep AS5 is overwhelmingly praised by consumers seeking a truly luxurious, ultra-plush sleeping experience, successfully fulfilling its promise as the softest mattress in the Amerisleep lineup. Side sleepers, in particular, report exceptional satisfaction, frequently describing the feel as 'cloud-like' and noting significant relief from pressure points in the shoulders and hips. The proprietary Bio-Pur memory foam is often highlighted for its responsiveness and ability to minimize motion transfer, making it an excellent choice for couples. Furthermore, many users appreciate that the AS5 sleeps cooler than traditional memory foam mattresses, addressing a common industry complaint. However, the mattress’s defining characteristic—its extreme softness—is also the source of its primary criticism. Consumers who are heavier or primarily sleep on their stomach or back often find the AS5 lacks the necessary foundational support, leading to complaints of slight sinking or misalignment over time. This polarization means that while satisfaction is extremely high among its target demographic (those needing maximum cushioning), the mattress is unsuitable for those requiring a medium-firm or firm feel. The high price point is frequently mentioned, positioning the AS5 as a premium investment, but for those who prioritize deep pressure relief and plush comfort above all else, the consensus is that the AS5 delivers a high-quality, specialized sleep solution.
