Worst mattress ever i had

¡Look what happened to us! At ten months of purchase Simmons Melissa mattress plush firm, the mattress began to divide it, being half of the mattress more sunken than the other half. When my husband lies forms a hole in which I spend the night at the edge of the mattress struggling to avoid me as if you were on a cliff. We claimed to Simmons and although they agreed that there was a compaction and answered that the filling of this mattress is prone to compaction, they decided the compaction the not exceeded the established tolerance to honor the warranty. We bought a firm mattress and have to wait for Simmons to decide when it is that I can get out of the hole and sleep like everyone deserves. This is the worst mattress I bought in my life and the worst are the Puerto Rico people of Simmons, who sent me a letter and not even be deigned to sign it.
