Different and the Same

When is the last time you replaced your mattress? My husband and I decided that ten years was long enough between our last mattress and a new one. And before that, it was ten years between mattresses. So, today, a new mattress is being delivered to our house and the old one is going away.
The old one was purchased when I was pregnant with my daughter. It has dips on each side where my husband and I have slept over the last decade. The springs aren't as comfortable and the pillowtop is more flat than cushiony. It was time. My shoulders every morning concur in their aches and stiffness.
The thing is, in the last ten years, mattresses have changed and improved quite a bit.

We walked into the furniture store and the salesman immediately showed us to one of the most expensive types of mattress, just to see if we liked that style. It's memory foam and is supposed to conform to your shape, keep you cooler at night, and make sure you sleep better. Add in the adjustable frame to go under it, and you're guaranteed to sleep better than you ever have before.
We didn't go with the highest end mattress, but we did get one higher than we'd considered before. Thing is, it's a totally different style than the pillow-topped spring mattresses we've had in the past. And, supposedly, this one will last thirty years as opposed to ten. That also sounded good, considering how much it cost up front. And we applied a store credit to the bed frame so we can prop ourselves up on nights when we're congested.
That said, I teased my husband about us having to agree how much we want it propped up and how much we'd adjust things since it adjusted the whole bed and not just one side or the other. The store clerk informed us most couples don't argue over that, but tend to agree very quickly about how the bed should be.
I don't know if that was just a sales pitch or if it's true, but we'll soon find out. We've been married almost 20 years now. If this mattress lasts as long as promised, we won't have to replace it until we celebrate 50. That sounds good too.
So, as much as things stay the same, they also change and evolve in our marriage. Sometimes they improve like the mattresses. Sometimes there are added things to test us like how much to adjust. But either way, as long as we stay together and work it out, it's fine. And it will only continue to get better.
How about you? Have you had to go mattress shopping lately? Did you give in and get a fancy one like we did?
