Below, we explore the key features that make the AS3 a popular choice. Each feature targets a specific need for better sleep.
Construction And Materials
The AS3 uses a five-layer foam design. The top layer is made of Bio-Pur foam, which feels soft and breathable. This foam is eco-friendly and reduces pressure points. Below that, memory foam offers gentle contouring to the body. The support layer is made of high-density polyfoam. This layer keeps the mattress durable and stable. The cover is made of soft, stretchable fabric for extra comfort.
Comfort Level And Firmness
The AS3 has a medium firmness, rated around 5 to 6 out of 10. This level suits side and back sleepers well. It balances softness with enough support to keep the spine aligned. The top foam layer cushions pressure points, helping reduce aches. It feels plush but not too soft, avoiding sinking too deep.
Support Technology
The mattress uses a special foam called HIVE technology. It has hexagonal zones that change firmness in different areas. This design supports the hips and shoulders better. It also helps keep the spine in a neutral position. The support layer adds extra lift to prevent sagging. This technology aims to reduce tossing and turning during sleep.
Temperature Regulation
The Bio-Pur foam is open-celled, letting air flow easily. This helps keep the mattress cool at night. The cover fabric also improves breathability. The mattress does not trap heat like traditional memory foam. Sleepers can expect a cooler and more comfortable rest. It suits people who often feel hot while sleeping.
