^^^^ I've got a good mattress, but a sh1t bed frame, so I cannot wait for the new one. I have a feeling when you get into your bed, it will feel pretty epic!
The difference just changing the bed frame from a divan to a proper metal bed was amazing I woke up feeling rested instead of feeling knackered, so I thought I would treat myself and replace the 10 year old mattress as well.
When I took the old bed to the tip I had to chop it up to get it into the car and after seeing how it was built I wont be buying another divan, it didn't have the support it should that's for sure it was crap for what it cost.
My new bed has 2 rows of proper slats, the divan was 2 wooden boxes with cardboard stapled to the top and then covered in fabric
The new mattress is sprung then it also has a layer of memory foam on top of that, I had a devil of a job getting a fitted sheet that would fit over it as it is a lot deeper that a standard mattress.
