Sleepwell — Sleepwell mattress

Really disappointed on entire experience with team Sleepwell. After lot of research and guidance from the store we purchased Serenity mattress which cost around Rs.32k. After few months the mattress started loosing firmness and now is the cause for major spine problem as it does not provide required body support and feels like sinking inside the mattress. Even after explaining detailed issue on the customer care, the complaint was handled poorly with standard rebuttals
While we understand limitations for free exchange, all we were looking for a solution and now feel helpless with the monetory loss + discomfort. Complaint #46945 with all contact ans issue details registered with Sleepwell. Need a resolution ASAP
