We bought a mattress in 2018 and as per the product tag sheet it says manufactured in 2017. Though the company claims50 years of blissful sleep, within a span of 3 years the mattress has crumpled on 1side , lost its firmness/ resilience making it absolutely uncomfortable and impossible to sleep on thatside causing one to roll off the mattress towards the edge and lose balance.
Do not be taken in by the fancy advertisement and fall for a poor quality product and a 100 percentwrong buy.
