Hi scherzo,
I’m not familiar with this foundation and the quality of the wood it uses, the distance between the slats, the amount of flex it would have on the support surface, or how much weight it could support so I really don’t know. There are a number of complaints about the quality of the wood and materials and the time and effort it takes to put together but the good news is that if you are one of those that run into the same problem then WalMart has a great return policy.
There is more information about foundations that would be suitable for different types of mattresses and some sources that I’m more familiar with in the foundation post here that you can use as a reference.
If the distance between the slats isn’t more than about 5" or so (and that would be on the edge of what I’d be comfortable using with a mattress with a polyfoam base and smaller gaps would be stronger and more evenly supportive), the quality of the wood is good, and the manufacturer indicates it will support the weight that would be on it (the mattress and the people sleeping on it) then it would likely be OK.
