Both of our bed mattresses are around 13 years old (Diana's is in our guest room). While hers sags in the middle, making it difficult for two people to sleep in, mine is plagued by uneven springs that make funny noises when you roll around.
The outcome of this bed tragedy is that we're both waking up with funny aches and pains all of the time. It's particularly bad for her given the previous vertigo-induced string of neck and shoulder pains.
So between the honeymoon and carpet debt, I'm obviously in no hurry to shell out for a bed, but as soon as Diana pays off the debt she incurred for the wedding, she vows to buy a new mattress. I feel bad because I'm used to being the provider, and if I were making day job money I'd just run right out and we'd buy one.
