Is it true that a mattress or a bed leads to most sinful actions?

[An online spiritual discussion was conducted on May 30, 2021, in which several devotees participated. Devotees’ questions answered by Swāmi are given below.]

[Smt. Ramasundari asked: Swami, I was listening to the Bhāgavatam being explained by one of the famous spiritual preachers (pravacanakartās). While explaining, he said the mattress or the bed is the most sinful object in this world. He said that being more associated with it leads us to do sinful actions. I remember very well that in my childhood, upon waking up in the morning, beds and cots would be kept aside and would not even be touched until it was time to sleep at night. Nowadays, these mattresses are a part of everyone’s home décor. Is what that scholar said, correct, Swami?]

Swāmi replied: I also don’t know how mattress is sinful. Please ask him and pass on his answer to Me also. I know one thing scientifically and also through experience that these spongy beds transfer heat into our bodies, which brings some illness like body pain.
