You never forget that feeling of your first time.
But getting back to mattresses, all foam mattresses will degrade over time. It's the nature of foam elastomers. They take a set, can't avoid it. We went to the cheaper route and got a signature sleep matress from Amazon. It was great at first, but after 4 years it's time to replace it. But at $350, it's easier to justify replacing more often than some of the big name options.
Replacing a mattress early is the killer expense. We laid down some good money for a mattress we were ready to burn in 3 years.
I shopped and tried out the Purple, but it was very bouncy. Not our style. The iSeries worked well for us. Still have it in our guest room. Still like that one.
Fingers crossed for the new mattress. I'm not a huge fan of buying mattresses because they turn out bad.
