IKEA memory foam mattress...?

I was wondering if anyone has a memory foam mattress from IKEA or has laid on one before. I’ve been on a Tempurpedic one before and they’re amazing… but quite outta my budget. So the cheaper alternative would be from IKEA (minus shipping and handling :frowning: )

I need a new mattress for my new frame and would like to get some feedback on these specific mattresses if anyone has experience w/ them.

My other question is, the smallest one is 5" thick, now I’m 5’8" 200lbs, think it’ll bottom out?
