I agree that lately quality of the mattress has been going down. I have a 7-year old Klassic Plus mattress (Double) and it is still perfect. Whereas I bought another Klassic Plus (Double) in December 2009 and it has aleady sagged in the middle. After a complaint and multiple phone call follow-up for nearly one month, a person from Kurl-on visited to see the mattress. And after one week there was a letter from Kurl-on that the company is ready to replace the mattress but the transportaion cost (both ways) has to be borne by us ! What if the replacement mattress is also defective ? Is the customer again required to pay for the quality defect and fault of Kurl-on ? This is clearly an indicator of falling quality of Kurl-on mattresses. There are many good quality options (substitutes) available in the market and anyone who is planning to purchase a quality mattress (which cost anything from Rs. 15, 000 to Rs 20, 000) should go for them rather than choosing Kurl-on. On top of this, Kurl-on website sucks and no one responds to the complaint/feedback provided on the website. Kurl-on dealers also suck who think that after they have sold a mattress to a customer, he will never need another mattress again...they should be taught that there is something called after-sale service and word of mouth advertising which will come to haunt them if they act badly in attending to after sale complaints/feedback.
