I have a ~$200 Ikea spring mattress and it is terrible and has given me serious neck problems (pillow aren't an issues I use proper latex ones). Looking to upgrade, I know I qualify for Ikea's exchange program but I was wondering if there were any good alternatives out there e.g. Koala etc
Happy to spend at the upper range of my budget as I currently hate my current mattress.
I think your best bet would be to go to a mattress store and try out all the beds there. Mattresses can be very subjective.
