Hi. If I buy a Brooklyn Bedding Aloe Alexis mattress, would I need a foundation, or if I can just put it on my vintage bed frame, which has wood slats (they are loose, not attached). They may not be close enough together, but I can buy more to supplement. It’s either that or remove the slats and put a wire foundation (like the Powerstack sold by MyGreenMattress) within the old frame. (Note added later: this is a discontinued product from My Green Mattress Products)
Thanks for any advice!
Hi cathye,
It’s always best to check with a manufacturer about a foundation you are using to make sure it satisfies their warranty requirements but it would probably be fine for a latex hybrid such as the Alexis (which has polyfoam on the bottom of the mattress). If the mattress was all latex (including latex as the bottom layer) then the slats should be a maximum of 3" apart and preferably less. I would also try to secure them so they don’t shift and either fall through or create larger gaps and if your bedframe is one of the larger sizes then it should also have a good midbeam with support legs to the floor to make sure that the frame stays level and doesn’t sag in the middle over time.
Some of the better foundation choices I’m aware of are listed in the foundation thread here (which you may have already read if you know about the powerstack at My Green Mattress which is listed there).

Thanks, Phoenix. The slats on one of my beds are too far apart, so I was looking into a bunkie board. However, I didn’t like the solid ones, as I want the mattress to breathe. Then I found this – maybe a good option for people to know about! This item is unavailable - Etsy
Hi cathye,
Thanks for the link 
… although they aren’t really a bunkie board (which is solid and not flexible and goes over slats on a bedframe) but more of a slat set similar to some of the options that come up with a google search on “slatted bunkie board”. There is an example of a 2" slatted bunkie board with suitable spacing here but it is quite costly. There is also a bunkie board here with 2" spacing that is much less costly. Perhaps the best value option that could be used as a bunkie board I’ve seen is here which is available in a bare “slat conversion” version and upholstered version that can be used to add airflow under a mattress on a solid surface platform bed or as a bunkie board to add additional height or more even and solid support under a mattress (you can see the prices in post #6 here). Even one of the Ikea slatted bed bases here (which has some flex which may change how the mattress feels and performs) can provide good support and airflow under a mattress and are also economical
The slats you linked would certainly work if the spacing was good (and it looks OK based on the picture) but you would need to remove and replace the slats you currently have because they couldn’t lie on top of them.
