/kloc-is it a gimmick to try to sleep for 0/00 days?

100 days of trial sleep is really a good thing, not a gimmick. I bought a Heveya latex mattress before, and it is precisely because of the policy of 100 day trial sleep that I dare to buy it with confidence. I bought it and slept for a few days. It feels really comfortable to sleep, but my husband doesn't think it's suitable because he likes a harder mattress. At this time, the role of 100 day trial sleep comes, and Heveya can make changes according to the soft and hard needs of both parties. Now the mattress we sleep on is soft on one side and hard on the other. We are all satisfied.
