How much do I need to spend on a mattress

[Tinks]

I found with the cheaper mattresses at shops like Amart you can feel the springs when you lie on them. WIth the Ikea ones you can't feel the springs.

I always go by the rule of thumb of "as much as you can afford".

Personally I wouldn't go to AMart, but Bev Marks Beds have good quality affordable mattresses.
