Hi Angnjam,
Post #2 here has some of the better options and possibilities in and around the DC area that Iâm aware of and there are certainly some good latex options that you could test.
You can see some of my thoughts about Luxepedic in post #9 here. They may have a dimilar âfeelâ to the Tempurpedic Cloud Luxe but the layering is different and they donât show the density of the base layer so I would want to know that as well.
As you know they are a member here which means that I think they are among the best quality/value in the country. They use some premium foams in their mattresses and they also take more than usual care to match or exceed the layering, quality, design, and âfeelâ of the Tempurpedic line. Of course higher cost materials and design means that they are also not the lowest price available either for those who are strictly price shopping.
Diamond is a wholesale manufacturer who is making some âbetter than averageâ quality mattresses and I would certainly consider them if you can find out the details of all the layers. you can see more of my thoughts about them in post #2 here.
SleepEz is also a member here which means that I consider them to be among the best quality/value in the country and they have a wide range of latex mattresses where you can choose the firmness and type of all the layers.
The durability of a mattress depends on many factors and is relative to the person sleeping on it. You can read more about durability in post #4 here and the post it links to. 15 to 20 may be stretching it with any soft foam ⌠particularly if its not latex ⌠but depending on the degree of âroomâ you have left yourself with your comfort choice for foam softening and on the type of materials in your mattress 10 + would be within reason for most people.
Overall latex is the most durable of all the 3 categories of foam (latex, polyfoam, memory foam).
Temecula is somewhat âin betweenâ seveal lists on the forum but the better options that are within reasonable drivind distance would be listed in the San Diego / Escondido list and the Los Angeles list and the San Bernardino list and Palm Springs here (some choices in each direction :)).
