Good morning new mattress owner. That’s exciting! Remember, mattress protector, rotate, and maintence. Ok enough of the lecturing.
Foundation. Personally, I like the KD wood foundation you discussed. The semi flex foundation TM Mattress Makers Learn about Foundations Naturepedic video, how they build it Naturepedic - Notice the slatted foundation
Let’s look at it this way. Their warranty states in part
EOS® Product Limited Warranty
Who and what does this Warranty cover? This Warranty is not transferable and only covers you if you are the original purchaser and owner of the EOS (“Product”) and purchased it directly from Naturepedic or from an authorized dealer. Because we strongly believe in the quality, design and craftsmanship of our products, the EOS components when used normally for its intended purpose are warranted against defects in workmanship and material, as follows:
- A visible indentation in the mattress or topper greater than one and a half inches (1 ½”) that is not associated with an indentation or sag which results from use of an improper or unsupportive foundation or adjustable bed base. Normal wear requires that the mattress be continuously supported by a foundation or adjustable bed base with a proper bed frame sufficient to support the collective weight of the user, mattress, and foundation. Sufficient support is deemed to be a solid platform, a “bunkie board,” or a slatted base, with unyielding slats thick enough to support you and the mattress.
- However, the slats or supports must be no more than 3” apart. If they are more spread out than that it will not provide enough support and will void your warranty. In all cases Naturepedic may decide in its sole discretion whether sufficient support was used.
You purchased a $3000+ mattress. Do you want to risk that “conversation” should an event happen down the road? For under $800 additional for a foundation or less.
Full disclosure, I am using my previous semiflex box spring on my Plank Luxe, but both BB and Yawnder (where I bought it said my semiflex was better than BB’s slatted box spring). Would I do it again. No. I just changed my Mother in Laws BR semiflex with a low profile slatted (bargain zinus) and she noticed an instant improvement on her 3 year old mattress, but it made it easier to get in an out of bed with the lower profile. If I were to do it again, despite what I was told. I am going with a box spring such as the one you saw at @DLX mattress. It is just way better built, no issues with the base foam pushing through the wider spaces of the semiflex and no sleepless nights worrying if that semiflex got bent, or has any wear and tear issues over previous use.
Could you use you old semiflex, sure. My advice, it is just not worth the risk. I forgot what happened with the mattress that was on that foundation to begin with, but poor foundations are sometimes the weak link in a bedding system. Although you could swap out any layer of your EOS as @TheCleanBedroom Katie mentioned in one of her previous as always knowledgeable responses.
Hi, punkrockrosebud, welcome to TMU. @Maverick mentioned us as an option, so I wanted to chime in, especially with Naturepedic. Since you have some preferences regarding latex, I wanted to mention that any layer of latex in the Naturepedic EOS mattress or EOS Pillowtop can be swapped out for coils to make that layer and/or the mattress latex-free, or lessen the number of latex layers. As Norm mentioned, you can swap out the layers after purchase also if something is not working.
The one issue I have with if something goes wrong, just swap theory, you dont know which layer is caused the problem, if one presents itself, and you end up swapping more than you bargained for.
Hopefully, this is some food for thought.
Good luck and congratulations on your new mattress!
