Hi TechieTechie,
Thanks for confirming that Costco’s newer Cocoon version is a lower grade variant of the older Cocoon mattress you own, It was certainly worth a try. It looks like you gave up on the idea of getting an interim mattress for a while… either way, we are back at square one.
Just to confirm that you are not reacting to something in your Naturally Nestled topper, you may want to sleep on the Cocoon in the guest bedroom for a night or two and add the NN topper to see if you still wake up with “itchy eyes and wheezy breathing” allergy symptoms.
To thoroughly eliminate any allergenic residue on NN’s toper, I’d either air the entire toper out or unzip and wash the cover in lukewarm water before sleeping on it in the new location. This is unlikely but you may still want to check if your sensitivities also include latex. Latex comes both in natural and organic so this may be a logical material choice to use in your mattress.
A component style system with zippered cover will allow you to fine-tune the overall feel of the mattress but you’d need to check on any Fire-Retardant solutions used to ensure they are not chemically based and trigger your allergies. Read more about fire barriers such as viscose/silica (not wool) inherent fabric (see post #2 here ) ) but there are also other types of inherent fire barriers as well. As you seem to be allergic to wool then I’d try to find some good quality plant-based covers such as organic cotton/bamboo/Tencel etc.
Most of our Trusted members have hybrid-latex or all-latex beds but you’d need to individually check if their covers and constructions meet your criteria needs. Depending on the type of mattress you settle on you may need to do some mixing and matching with components from different companies.
Some that quickly come to mind are
~ Luma Sleep has more of a modular system both hybrid and all latex. Here is their product specs page for a quick overview. Their cover is Tencel and the design includes a base mattress to which you add a “pillow Top” if more comfort is needed
~ Arizona Premium has Organic Cotton zippered mattress covers here and you can also get Ken to help you build either a hybrid latex or all latex depending on your preferences.
~ SleepEZ also has 9" to 14" tick organic Latex Mattress constructions both natural Talalay and Dunlop (NR and Organic) Shawn, Roger, and Jerremy are excellent “mattress matchmakers”
~ Flow Beds has a components style system all-natural latex Talalay mattress, but it looks like their cover contains some wool You’d need to call and ask if they have a non-wool zippered cover version.
All listed above are also mattress experts with their dedicated forums on our site and you may want to reach out to them with any questions you may have about their products.
Remember that when you can’t test a mattress in person then the most reliable source of guidance is always a more detailed phone conversation with a knowledgeable and experienced retailer or manufacturer that has your best interests at heart and who can help “talk you through” the specifics of their mattresses, constructions, and the properties and “feel” of the materials they are using (fast or slow response, resilience, firmness, etc.) and the options they have available that may be the best “match” for you based on the information you provide them, any local testing you have done or mattresses you have slept on and liked or other mattresses you are considering that they are familiar with, and the “averages” of other customers that are similar to you. They will know more about “matching” their specific mattress designs, options, and firmness levels to different body types, sleeping positions, and preferences (or to other mattresses that they are familiar with) than anyone else.
Let us know of your eventual decisions and additional questions as you move forward
