Hi robr,
I’m sorry to hear that you are not enjoying your UD Eurotop mattress after three years and that it seems to be too soft for you. All foams soften a bit over time, and the mattress you chose was a bit on the softer side of the comfort scale, and wasn’t an all-latex, but one with a poly-foam core, so it could be this gradual softening that doesn’t agree with you. It could be that based upon your experiences while traveling that you’d be better served with a mattress using more traditional springs for the support unit versus a polyfoam core, and then firmer comfort layers above that spring unit. Latex is the most durable of the foam padding materials used in a mattress, so if I had to make a more educated guess it would be more the overall plushness and combination of materials with the support core chosen in your past two mattresses that are working against you. If you don’t wish to us latex for a comfort material, higher density polyfoam (1.8 lb or above) might also be worth considering.
If you do decide to test items locally, which is preferable for many individuals, just make sure to find out the information listed here so you can compare the quality of the materials and components to the durability guidelines here to make sure there are no lower quality materials or weak links in any mattress you are considering, just like we discussed a few years ago. If you need to refer back to any of the steps, just click on the link here for the mattress shopping tutorial, which has been revised since our previous conversations.
If you come up with more specific questions about something you see, I’ll do my best to answer them for you.
