Kluft mattresses are designed to last for more than 10 years where the industry standard, is typically 6- 8 years. However, if you notice an uneven wear in the mattress, feel that your comfort is compromised or wake up with chronic back or neck pains, it is an indication that you might need a new mattress. So listen to your body always. You can also rotate your mattress from head to toe every three to six months to ensure that the weight is distributed evenly across both sides and prolong the life of your mattress.
