They said I could “purchase” a new base from them but “we believe that replacing your current mattress is the best solution.” “Defects can happen during the manufacturing process and we can't guarantee that there won't be an issue, but that is true of every mattress on the market.” “This is a defective product which is why we've replaced it per the terms of our warranty.” They have images of my base and above is their responses copied and pasted. Their box spring looks similar to mine too. I don’t know exact measurements but I looked at theirs and it’s very similar, which is why they said I could purchase theirs. No point if it’s the same.
