Which IKEA mattress is very firm?

[Zamaos]

The kids have an IKEA bunk bed would really like a very firm mattress. They currently have an IKEA memory foam one which has sagged in the middle and really needs changing.

Does anyone know which IKEA mattress is genuinely firm.

Bump!

I had an ikea mattress that sagged. I found if I turned it over (even though it wasn't "Meant" to turn over) often once every couple of months it seemed to refirm. This did mean that I had to sleep on the side that wasn't meant to be slept on, but actually it was fine (you could use a blanket or something as extra padding if necessary). It meant I could use it for years beyond what I would have otherwise.

@ethermint thanks. I actually have turned it over regularly but I think it's just sagged now to the point that it really does need replacing.

I think there's a Which recommended ikea mattress but can't recall the name of it. Might be worth doing a google.

I have a SULTAN Ikea mattress which is very firm. Had it for 8 years and still quite firm. Not sure if they still do it as they seem to change the whole lot every few years. I find it so firm, I use a Simba topper on it so that it's soft but firm underneath,
