Novosbed medium firm vs Silk & Snow hybrid

I’ve spoken with both companies and would like to provide the following updated information so that others may benefit:

Novosbed: confirmed the specs you provided are still accurate.

1" - 1.95 lb / 9 IFD - 5th generation premium airflow foam
1" - 4 lb / 11 IFD - 5th-Generation high-density visco-elastic memory foam
2" - 4 lb / 11 IFD - 5th-Generation high-density visco-elastic memory foam
7" - 1.75 lb / 32 IFD - Premium support foam

Silk & Snow provided the following specs for the hybrid:

Coils
Twin - 600 pocket coils
Twin XL – 621 pocket coils
Double - 800 pocket coils
Queen - 1000 pocket coils
King - 1200 pocket coils
California King – 1204 pocket coils

Coil Gauge
Outer Thirds - 14.5
Middle Third - 13.5

Zoned Lumbar Support
The middle zone (middle third) of the mattress uses thicker coils. This guarantees reliable and balanced support. Sink in just enough in just the right areas, with extra support under the hips and slightly softer coils under the shoulder.

Mattress Construction
Cover
Polyester/Spandex/Antimicrobial Cover

Top Layers
1" Luxury quilted cooling gel foam and hollow fibre that helps keep you perfectly cool
2" Gel memory foam that provides superior relief for pressure points

Edge support
Same density as in the middle.
