Hi Syracusa,
The foundation post here has more information and suggestions about foundations that would be suitable for different types of mattresses and also includes a link to the guidelines I would use for a metal bedframe (near the end). In the case of a latex mattress I would make sure a slatted wood foundation had gaps between the slats that were no more than 3" (preferably less). I’m not sure if the Ikea Aram foundation would meet the criteria but I would guess that it doesn’t and I would avoid a foundation that used a cardboard surface that doesn’t allow the mattress to ventilate. Any of their slatted bases on a suitable bedframe would be fine.
