These mattresses that come in boxes. I'm thinking Emma, Simba and Eve.
I've currently got an IKEA mattress and it's sunk a lot in the middle. I am overweight but I cannot sleep with my hips dipping down. My mattress is only 2 years old (and I'm a size 16).
I'm at a point where I can spend a bit extra if needed to get comfort and a product that lasts a long time.
Looking for something quite firm as neither of us like to sink into a bed, but do like the memory foam feel.
Thanks
