However, the mattress is not compressed into a smaller box for delivery, which could make it cumbersome to move and set up. Its heavier weight at 119.4 pounds adds to this challenge. The edge support and motion isolation features are effective due to the combination of pocketed coils and memory foam, which can be advantageous for couples sharing the bed. In terms of durability, the mattress is designed to last, but proper care and the use of a mattress protector are recommended to maintain its lifespan.

This mattress may be challenging to handle due to its weight of over 100 pounds and its non-compressed delivery format. Some users may also find the firm feel too stiff if they prefer a softer mattress.

Durability seems promising, but long-term performance might vary based on individual usage and care. This mattress is best for those who prioritize firmness, cooling features, and robust support in a hybrid mattress.
