I've had my Kingsdown latex and foam mattress for at least 12 years. There is an indent where we sleep now, but it's still extremely comfortable. I bought it on a whim because it was on clearance and it's the best purchase I've ever made. It's insanely heavy and has no carry spots; it took 3 adults struggling to carry it when we moved. That's my only gripe!
I've been very happy with Kingsdown, which you can also get at Sleep Country among other chains. It's also Canadian, along with a bunch of other manufacturers that've been listed here
We are currently replacing two Kingsdown mattresses - one is twenty years old and one is twenty five years old. They were warriors and I don’t regret the purchases. I have no idea how they are made these days but they were made very well when we bought them.
We recently moved , and went to pick out a new mattress. Together at the store, we laid on several, and selected a Kingsdown mattress. It’s been a wonderful one! I’m menopausal, and take medication that causes even more night sweats, and the mattress is still comfortable. It’s the perfect firm / soft combo as well.
Of course, I always use a mattress cover to protect the mattress.
We’ve had our Endy for 5 years. It’s quite comfortable. I am 200# and have noticed a bit of a depression where I sleep, but I rarely wake with a back ache. Had a Kingsdown before, was more expensive, and broke down in just 3 years.
