Nothing but the best? Kavaro's the one for you. It has a pocket sprung centre that’s sandwiched between an indulgent mix of cotton, wool, silk and cashmere. It’s made with 2000 pockets, each one housed in a fabric ‘sock’. This keeps them separate so each one can drop or raise individually as you move. So you can toss and turn without waking anyone up.
We both have slept well since first night ;supportive but not too firm.
On my side
Can change positions without disturbing other person, more a medium-firm mattress than a very firm mattress.
Its a long matress. I'm 6ft and my feet don't go over the end!
