I'm angry because I've only had my mattress for about 4 years and it's starting to sag in the middle (I weigh <70kg).
I spent $500 for a single size mattress, so definitely not budget but obviously not high-end either.
Dug up the receipt and see warranty is one year. Now I'm even more angry! Is there anything I can do?
What brands do you recommend that won't break the bank but will last?
