Hi MikeJ,
Welcome to the Mattress Forum! 
[quote]Am a semi-regular at Hyatt, and their Hyatt Grand Bed II, with the Euro Pillowtop, works great for my lousy back and neck (degenerative disc-back and stenosis-neck). I was ready to look into purchasing the combo, but see on their website that they’ve discontinued the mattress sales.
Question: can anyone advise how I could replicate this mattress and top? I’m desperate!![/quote]
“Hotel mattresses” tend to be more basic versions of the retails products that many mattress companies offer (which isn’t a good thing). They tend to be firmer products using softer “top-of-bed” materials to create extra plushness. There’s more good information about hotel mattresses in post #3 here.
The Hyatt Grand Bed II is not much different from a “normal” Sealy Posturepedic (being a Eurotop is a method of assembly and not a comfort designation). In most cases … hotel bed purchases are disappointing and like all major brands they contain a lot of polyfoam which is subject to early softening and breakdown. There really isn’t much value there. If you did want to replicate your experience at the hotel … at least for a little while … then you would also need to buy the whole ensemble (or at least the topper or feather bed depending on which one you slept on and probably the triple sheets which will also contribute to the feel of the bed). This would add even more layers that were subject to softening and early breakdown. There are also a lot of unhappy people who have bought this mattress in the past and complain that it feels nothing like what they remember.
Without the specs (and they don’t reveal them … not even the coil count) it’s not possible to approximate the mattress. Quite frankly you could do better “replicating” the mattress just by lying on some of the Sealys in a store and adding a topper or a featherbed, even though this would also be a poor choice. You can see some examples of Sealy Hotel mattresses ADMIN NOTE:Removed 404 page link | Archived Footprint: innroomsupplies.com/v/vspfiles/pdfs/BedsRollAwaysFrames_Website_InnRoomSupplies.pdf here and ADMIN NOTE:Removed 404 page link | Archived Footprint: docstoc.com/docs/85262959/SEALY-MATTRESS-AND-FOUNDATION-SETS-HOTEL-COLLECTION-SEALY-here and here and as you can see they range from plush to firm and have a variety of different types and quality levels. In general though they will be layers of plush foam over a good quality innerspring and cater to a “feel” that the majority of people would enjoy in the short term sleeping environment of a hotel stay. This doesn’t necessarily translate into a mattress that is suitable for longer term use.
What I would suggest though is to start from the beginning and test for the pressure relief, alignment, and overall feel that you need and prefer, and best try to approximate the feel that you prefer while travelling, but doing so using product containing quality materials. The guidelines expressed in the mattress shopping tutorial here are a good place to start. You would more than likely prefer something using higher density and firmer foams, with perhaps softer higher density polyfoam in the upper quilt panel or perhaps a latex topper, for a more durable plush comfort. Something along these lines could provide a feel that is in the range of what you experienced in the hotel, but it would have a longer comfort life.
If you provide me with your zip code, I can see if I am aware of any retailers in your area who might be able to provide quality products or assistance in your search.
