Adding a second latex layer to hybrid?

First time latex hybrid DIYer here. Current set up is 8in TPS coils 15.5 with 3inch soft Talalay topper. I have heard some say “less is more” when constructing a DIY latex-hybrid. For example, one 3inch topper on top of coils should be enough? The 3inch topper is too soft and not supportive enough for me and my wife who are same height and weight (6’2” 180lbs). Would you recommend a medium or firm 2 or 3 inch talalay or Dunlop underneath to firm it up? We want to keep the 3inch Talalay on top since it was a big expense and don’t want it to go to waste since there is no return policy on it and it’s not entirely too soft but enough to consider other options. TIA!

Hi LuckyLatex,
Welcome to the Mattress UnderGround.

The idea behind “less is more” is that you don’t always need multiple thick comfort layers to achieve good support and comfort. Sometimes a firmer base (like coils) combined with a thinner or more supportive topper can work better than multiple thick layers of soft material. This could be part of your issue, the 3" Talalay may just be too thick and plush for your needs. But we dont know because you have not provided the Talalay layer specifications. You stated soft, but are you saying 14ILD soft, or 19ILD? Every company will have their own variation of what they think is soft, medium, or firm. Many will suggest that a dunlop mattress layer of under 14ILD is not recommended for the comfort layer of a mattress.

Since you want to keep the 3" Talalay on top, and assuming it is a very soft layer, like a 14ILD, adding a firmer layer underneath could definitely help.

Medium to firm Dunlop (2" or 3") would be a great option for this. Many people will suggest that Dunlop will feel firmer, but quality made, dunlop and talalay of the same ILD should feel quite the same. Non the less, it will add some firmness while maintaining a latex feel, and help reduce the softness that you’re currently feeling.

Medium Dunlop (2-3"): A medium layer will provide a more balanced feel and prevent the mattress from feeling too soft.

Firm Dunlop (2-3"): If you’re looking for more significant support, a firm Dunlop layer could really firm up the mattress, making it more supportive for both you and your wife, especially at your weight.

The soft Talalay will still give you the pressure relief and comfort you want.

The Dunlop underneath (medium or firm) will provide more support and keep your body aligned, especially for side sleeping or back sleeping.

Since you’re committed to using the 3" Talalay topper, the idea is to adjust the base layer to complement it, rather than replace it entirely. This maximizes the value of your existing investment.

If you take a look at European Sleep Works Alpine Classic Talalay, it is basically quality nested spring support with 2" of Talalay Latex, and a nice stretch cotton and wool cover. So when considering the less is more concept, you can see how a popular and quality mattress is constructed of basic, quality materials with minimum amount of layers.

Hope this helps,

Mavick

2" of medium dunlop should do the job of keeping you from sinking all the way through to the coil. 3" is usually enough but for someone of your weight I normally recommend 3" of #28 instead of #19.

Wow, was not expecting such a fast and thorough response, Mav & Ken- thank you. And thank you Ken for the clean and quality latex we ordered from you and the awesome bamboo cover. Our 3 inch Talalay is 19ILD. Wife and I love the feel of latex. She has hypermobility (connective tissue disorder - causing severe joint pain) but she also loves a soft mattress like me but of course being more supportive of joints is top priority so it can be tricky. Since now knowing the Talalay is 19ILD would you suggest a 2 or 3inch transition of medium or firm Dunlop? TIA
