Sir/madam
I purchased bed in amazon
When i am using memory foam mattress my backpain got increased and unable to sleep more than 3 hours
My backpain got increased while using this bed
I contacted the seller, he said use the bed for atleast one week then only your body will adjust, i used for 10 days but still i am facing the severe pain, i am not using the bed since 3 days, now he is not responding

I asked refund for this product because its a defective, if they fail to provide refund i asked replacement, but they are rejecting for that

I raised amazon a-z guaranteed claim policy, but they denied my claim
In sleepycat official website they mentioned 30 days free night trail but they are not agreeing for their policies
I am sharing 30days free night policy and refund policies
