Hi Paul, I've done some research on the Salus you've been looking at it's hard to be exact as the details around their components are very minimal, for example it doesn't tell you the density of the foam or the gauge of the springs.

The main differences between that and the hybrid 7 are: Hybrid uses coolblue which is a hybrid foam, more advanced than memory foam in that it is more responsive.

Hybrid comes with a 7.5cm topper which is removable and turnable.

Hybrid has fully boxed FEPs the Sallus doesn't state this so we assume its tray FEPs, though we can't be certain.

Hybrid is 32.5cm deep.

In terms of tension based on its description I'd assume it was 70kg memory foam and with that would say our tension is similar for coolblue.

I'd summarise by saying you get a lot more bed for your money with the hybrid given the topper and depths.

I hope that helps Paul.
