How firm is the 600 Lux mattress?

Why are REM-Fit springs superior to your counterparts?

Unlike our counterparts we use tall pocket springs constructed from triple tempered steel. Each spring is contained within its own pocket of fabric which prevents the spring system from rubbing against each other, nothing worse than a squeaky mattress! Tall pocket springs compared to mini springs (only) provide superior support and will isolate partner disturbance movement more effectively. Don't worry about feeling the springs through the mattress, you can't, we place them deep beneath the top layers of the mattress so that they are never noticeable.

What base can the mattress go on?

Thanks to the high-density foam layer of the mattress you can confidently use the mattress on any bed base including adjustable beds!
