I’m building a DIY mattress using pocket coils (15.5 gauge) with a memory foam topper, but it’s coming out too firm. I think I need a transition layer between the coils and memory foam but can’t decide between 2" or 3" thickness.
How much does the thickness actually matter for comfort/support?
Also considering latex for the transition layer - what’s the real-world difference between Dunlop and Talalay latex? Is one better for a transition layer specifically?
Thanks!
Hello lcs207,
The thickness of a transition layer does impact the overall comfort of a mattress. In your case, a 2" medium Dunlop layer may work well as a transition layer—especially if your memory foam topper is 3" thick or more.
Dunlop latex is heavier, denser, and inherently firmer, which can provide added support beneath the topper. Talalay latex, on the other hand, has a more open-cell structure, making it softer and more pressure-relieving. This would create a noticeably softer overall feel beneath your memory foam topper.
Let us know how it works out, and thanks again for reaching out!
