IKEA Vesteröy

I bought this mattress based on Choice's 2nd place rating in their 2025 mattress review. What a piece of garbage! My partner & I are both under 70kg but after just one month it was starting to sag where we lie and there was a hump down the middle. It's on an Ikea base and the slats are firm, but I put a board under the whole mattress, just to be sure, and it made no difference. After 3 months, despite rotating it lengthwise several times during that time, the hump is more obvious and there is definite sagging both sides. Now I'm back to mattress shopping! Ikea lets you swap within a year of purchase, but even if I pay another $1050 for their top of the range mattress, I can't trust that the same thing won't happen. Very disappointed Ikea!
