DIY Build - 5'11" - 160lbs - 22BMI - Side-Sleeper in Canada 10 Jun 2022 13:18 #1

Hi all!

I've been creeping for the last couple of days, ingesting all the info on this awesome site (amazing that this exists, by the way). I was hoping to get a bit of advice on a build I'm contemplating. Money is fairly tight, but I also want something of good quality that will last.

Quick backstory: I bought a Douglas before I knew anything about mattress construction. It was great for the first 30ish days, but the top 2 layers (2" 10ILD and 2" 11.5ILD) have since softened up, and I just feel the 32ILD support base under my shoulders and hips, with very little lumbar support. So it's going back since I'm still in the window.

5'11" - 160LBS - 22BMI - pretty much exclusively a side-sleeper - Thin with broad shoulders.

Mario at MFC was very helpful with all my questions about foam types and configurations, but I didn't want to bug him further haha. I'll be using MFC for everything since he was so helpful.

I have my 5 year old Sealy Posturepedic Optimum, which I'm going to do some surgery on and hopefully use the opticore, which Sealy's brochure on this model says is an 8" with Coresupport, which I couldn't find any info on (The smaller, 6" Opticore is: 4" of 32ILD poly under 2" of 20ILD poly) but if that doesn't work out, I want to have the full DIY build figured out so I can move on that quickly and not buy anything I don't need.

For the full DIY build (bottom to top):

3" - HD 2lb / 40 ILD
3" - HR 2.75lb / 28 ILD
2" - HR 2.75lb / 20 ILD
2" - Organic Dunlop 4lb / 20 ILD

I'm hoping for a mixture of support and no pressure points, with a cooler sleep surface than with memory foam (high bar on a budget). Talalay is very expensive and not super available in Canada by the looks of things.

All I have for reference is my Sealy (cheap materials, wore out much faster than I hoped) and the Douglas (top layers too soft, 32ILD hurts when there's no cushioning or support)

Does this mixture sound in the ballpark?

Thanks in advance!

Hi SleepyChrister.

Welcome to our Mattress Forum. :)

We are so glad you have found the resources useful and that Mario at MFC has been a guide in your journey towards a DIY!

For the full DIY build (bottom to top):

3" - HD 2lb / 40 ILD
3" - HR 2.75lb / 28 ILD
2" - HR 2.75lb / 20 ILD
2" - Organic Dunlop 4lb / 20 ILD

I'm hoping for a mixture of support and no pressure points, with a cooler sleep surface than with memory foam (high bar on a budget). Talalay is very expensive and not super available in Canada by the looks of things.


This looks like a very supportive and durable build. The latex will definitely sleep cooler than a poly/memory/gel foam. I think the 20 ILD foam under the 20 ILD dunlop will help create a solid "cradle" for the curvatures in a side sleeping profile.

What's your Sealy surgery plan?

Hi Nikki!

Thanks for replying!

Perfect, that's exactly what I'm hoping for. I've had both piriformis syndrome and a tear in my deltoid before, so finding the balance of support and while allowing the sensitive areas to sink in and not just get smashed against a firm surface is tricky.

For the Sealy surgery:
I think the coresupport is shot, which also means the quilted cover, and possibly the first 2" of comfort layers might also be worn unevenly. Hopefully the shoddiness stops at those layers.

Ideally, the coresupport is still intact, so I can use that 8" core again, and just rebuild the top 4" of comfort layers for now. But I'll need to figure out what the top layer of the supportcore's firmness is. My idea for that scenario is this:

- 8" core support (assuming 32 ILD)
- 2" HR 2.75lb / 20 ILD
- 2" Organic Dunlop 4lb / 20 ILD

In the event the opticore is shot as well, the alternate budget build I thought of was:

- 6" HD 2lb - 30 ILD
- 2" HR 2.75lb / 20 ILD
- 2" Organic Dunlop 4lb / 20 ILD

I should be getting the Dunlop topper this week, so the surgery can begin and I'll see what I'm working with.

I totally messed up the nomenclature in this sentence. It should read like this so there's no confusion:

"Ideally, the opticore is still intact, so I can use that 8" core again, and just rebuild the top 4" of comfort layers for now. But I'll need to figure out what the top layer of the opticore's firmness is. My idea for that scenario is this:"

Hi SleepyChrister.

I hope the 8" core is still holding up so it saves you the trouble of having to match that piece!

I look forward to hearing your updates as you operate on your mattress.
