We have just bought our second super king, firm pocket sprung mattress (after 12 years of great sleep) and it is the best thing we have ever bought, twice! We also have an Isobella bed frame that is 12 years old. This has moved house twice and it is a good a new with no noises or squeaks. Impressive quality, built to last (both mattress and bedframe!). I was delighted to find LandF still selling these mattresses as they really are built to last and give an amazingly good nights sleep. The person next to you will not be disturbed or woken up if you move as the mattress is so well built!
