Fair point. It lasted 4-5 years solid. 6-8 clearly rapid failure.

Quickly is relative to the 10 year warranty.

I paid (usd 5k plus - king size) with a warranty in mind. Was told ‘our material is different, worth it’ - Full sales job. I’m technical, but details matter and they’re proprietary. I trusted the warranty + brand, which was a bad, expensive move.

Realistic expectations - memory foam lasts 4-5 years, more or less depending on pressure and humidity, and should be priced accordingly. YSK!
