Hi Dixie, happy to hear you are having a good sleep.
Your Lux 14" is Haven's most plush pillow top and was designed to maximize pressure relief for lux sleepers. One way we achieve this is using a secondary layer of bio-foam under the top latex layers, this specialty foam was selected as it remembers a body impression. Having the foam soften in a way to conform to the body shape, reduces pressure points and prevents tossing and turning through the night.
Now that your Haven is fully broken in, when the sheets and mattress protector are removed. lower sections will be visible. Between these slight wells, a higher lifted area is common. Much like a leather shoe or sandal will conform to the ball, heal and toes.
For an even distribution of these contoured areas, we recommend rotating the mattress 180 degrees every 3 months.
