    Falls down in one week

    The worst ever mattress , falls down in less than one week do not buy it

    Customers say

    Overall sentiment is mostly positive, with most reviewers praising comfort, supportive firmness, and easy in-box setup. The main drawbacks mentioned are that one mattress reportedly failed quickly and a few people found it softer than expected or slightly short on the listed height.
