Edendale Backcare Extra Firm Mattress

I've just purchased a sealy edendale extra firm and it's pretty much cured my bad back overnight

Are you rotating and flipping? I just got a sealy edendale extra firm for my bad back, and I'm 90kg. Yet to notice any issues in 3 months so far

I spent almost £2000 on a king-size Sealy mattress from Benson's for Beds a few months back. It's the most comfortable mattress I've slept on, more comfortable than the hotels I've slept in. It should last me many years to come, and so it's worth every penny to me. The ottoman bed frame I bought with it is also fantastic.

We are on an old watered frame with osb covering the frame.   We have an old Sealy extra firm king size box spring and mattress. We really liked the set up. But it's about 10 years past it's lifespan.  Do you have any recommendations for what to buy and/or where?
