Is sleeping on a mattress for free and sweating a scam?

Free mattress sweating is a scam. In order to allow consumers to buy a satisfactory mattress when purchasing a mattress, some manufacturers have come up with a solution called a 100-day free trial. This means that within 100 days, as long as you are not satisfied with your sleep, you can return it for free with free shipping. This seems to be a good decision and reduces a lot of decision-making costs for consumers. You can even sleep on a mattress for free for a hundred days or more without spending a penny. However, I believe that except for those who do reviews, no one buys a mattress to sleep on. You can return it within 100 days, which is great, but then you still need to make a decision again, read countless guides, compare N products, rely on other people's evaluations to imagine whether its sleeping sensation is suitable for you, and spend countless hours in it. , energy, even money. Reducing decision-making costs is obviously doubling the decision-making costs.
