Poor mattress longevity

We have a split king on an adjustable base. We think it was a good purchase, but not a great purchase. The mattresses are about 13 years old (Jul 2020). I had to have the material on the bottom of the mattress replaced as it wasn't much more than a heavy paper and it failed within about 5-7 years. It then wouldn't hold the mattress together. I took them to a local upholstery shop and had them fixed. The side foam isn't standing up. Also, the pump controller display started to fail within 6 years. Some of the LED elements failed to light. It eventually got to where most had failed and you couldn't determine the pressure. We replaced the pump/controllers with an off brand, that works better than the original. We're now looking for complete mattress replacement units.
