Help with split king - trying to pick the correct layers the first time

I have the broad strokes of what I would like to do laid out but am pretty lost on the details of what specifically to order.

We have a 12-year-old Simmons Beauty Rest Vivaldi Plush that has served us well but is beginning to age. My plan is to reuse its coils and build a DIY hybrid. We have experimented with a Sleep on Latex 3" soft Dunlop topper on our current bed and found it fine. It’s a hair firm for my taste and a hair soft for hers. I know the feeling will change drastically once placed on a proper support layer as opposed to a mattress, I just wanted to know if we tolerated the feel of latex.

[b]Sleeper A: 6’4" 185lbs side sleeper, prefers a softer bed, does not typically like memory foam
2" soft or supersoft latex (14-20ILD?, probably Talalay)
2" soft or medium latex (20-30ILD?, unsure if Talalay or Dunlop… it would be easier to nail down the transition if 25% and 65% ILD numbers were routinely published)
Beauty Rest plush coils

Sleeper B: 5’2" 120lbs mostly back occasional side sleeper, typically uses many pillows for support, prefers firmer and likes memory foam (but is not mandatory)
2" 5lbs memory foam
2" medium to medium firm latex (28-34 ILD?, unsure if Talalay or Dunlop)
Beauty Rest plush coils[/b]

I’m really struggling to decide between Talalay or Dunlop, and also the firmness of various layers. I know that Dunlop is more often suggested for transition or support layers but I’d like to have as much flexibility as possible in moving these layers around. I might get lucky and nail this first shot, but I’d like to leave open the window for tweaking. It’s part of the reason I tentatively chose all 2" layers; if it’s a better idea to do 1" latex and 3" memory foam, for instance, I’m all ears!

Budget is not super important, as any DIY will be loads cheaper than anything else we buy. For instance, if DIY fails my wife is probably just going to buy a Tempur-Pedic. I don’t particularly like them, so we’d end up with some weird franken-bed split king consisting of two different consumer mattresses. I would however like to be efficient. I’d feel wasteful making excessive returns or throwing out otherwise perfectly good bedding.

CN: please help me choose some specific layers that would give me the best chance of success, thanks!

I am in the process of figuring all this out too. where would you be ordering these latex layers?

It sort of depends on what exactly is recommended (not everyone has every spec). I’m open to most retailers with a bias towards Arizona Premium due to them being an incredible resource of knowledge and The Foam Factory because I stumbled across their site while searching and the product looks good.

Hi streetsweeper.

Thanks for sharing all of this and welcome to our Mattress Forum :slight_smile:

If I’m reading your post correctly, is this a proposed split configuration with latex on one side and memory foam on the other? I love it. I’d say lean towards Dunlop for that second layer; it tends to have more “push back” and is a bit more dense than Talalay which makes it a great supporting layer.

I also think your 2" idea is smart - like you said, more space to re-configure and swap things around.

Really, the best place to start is with the configuration you’ve got and then make the tweaks from there. Once you’ve had a chance to sleep on it you can gather some data points and bring them back here and we’ll all be happy to help!

Correct, one side latex and one side memory foam! Once you are already doing a split king you might as well get exactly what you want!

Thanks, I’ll save a couple bucks on the Dunlap transition layer and report back.
