Very disappointed and sad 😔 😟

I am very disappointed with your bed, I bought sealy posture premium at Bradlows in 2020 around November but since last year I no longer enjoy my sleep because of waist pains and I have already rotated the bed now 4 times and I thought I am the only one but even my husband is complaining about the same pains l, how long does your bed last actually? I am so disappointed I can't afford to buy a new bed but I wake up with pains my beauty sleep is gone it's not even 5 years using this bed and my husband he only comes on weekends so I am the only one who sleep on this bed all the time nah, what a waste of money
