Hi bluski,

It looks like the decision to redesign their Hybrid Latex mattress had to do with comfort & pressure relief as well, not merely cost savings. We had the former Talalay version of their Hybrid Latex mattress, and couldn’t get the comfort right as lightweight combo (side/back) sleepers. To their credit, Nest Bedding was very accommodating in trying to dial in the comfort level that we were looking, and even refunded us back for the mattresses when we couldn’t get situated with them.
We’ve since tried the newer Natural Hybrid Latex (my brother got that mattress), and think that Nest Bedding has resolved the comfort & pressure relief issues that we had experienced with their former Talalay Hybrid Latex. As the CEO of Nest Bedding notes in the thread referenced above, wool on latex can be a bit too firm/stiff for some people, which was our case. The new Eco-Flex foam certainly alleviates that, and provides a perfect balance between pressure relief (for side sleeping) & enough support (for back sleeping). We’ve tried over 10 mattresses personally, and investigated at least 20+ mattresses, and it’s the best mattress we’ve encountered. It feels like a traditional mattresses that we grew up - yet better.
As for the chemical concerns, there doesn’t appear to be any off-gassing with this product. My partner is sensitive to strong odors, and she couldn’t detect any. Also, it’s worth noting that most Talalay latex out there isn’t “natural” - but a blend of 30% natural latex rubber and 70% synthetic material. You’re likely going to run into some form of chemicals one way or another - or find firmer products that only use Dunlop (like we did with the Avocado mattress - which was waaaaaaay to stiff for us).
Plus, Nest Bedding’s warranty and lifetime comfort guarantee are tough to beat. One thing to mention about the Natural Hybrid Latex mattress from Nest Bedding - we did notice that it sleeps a little warm. Not excessively so (we didn’t wake up sweating or anything), but it was just slightly warm enough. Our sense is that a cooling/phase-changing mattress pad or cover should alleviate that. Not a huge concern, but something perhaps to consider.
So, honestly, having surveyed just about all that’s currently out there right now, we think the Nest Bedding Natural Hybrid Latex is one of the best options available at the moment. If we had a mattress review site, it would be our pick for “Mattress of the Year” - we think it’s that good. They really dialed it in with this one. And if you don’t like it, there’s always the Organic version, too.
Hope that helps, and definitely don’t hesitate to follow up with Nest Bedding’s customer service team. They’re super helpful. Good luck with your search, too!
