Hi carole,
This would be a completely different mattress design that they don’t offer on their site but it never hurts to ask.
The Eurotop does have the option of having different firmness levels on each side and another option would be to have a topper that could be added or removed according to your needs. You could for example add a softer topper for those times when your pressure relief needs are more extreme.
Memory foam and latex are very different materials and the choice between them is really a matter of personal preference. Assuming you were to choose the best type of layering in the comfort layers of each type of material … their pressure relieving properties are very comparable but the feel and performance of each is very different. You can read more about the pros and cons of memory foam here and the pros and cons of latex here.
If you were to choose a memory foam mattress … it is important to make sure that the quality of the memory foam is good (low quality/density memory foam is not a very durable material). Tempurpedic is good quality but poor value compared to many other memory foam mattresses that use similar quality materials. You can see some mattress shopping guidelines here and the first of these is to avoid the major brands which are generally much worse value than smaller independent or local manufacturers.
Memory foam can also be very tricky and I would be very hesitant to buy a mattress that had 7.5" of memory foam which I would consider to be a very risky construction. With any mattress … but especially with memory foam … the thickness and softness of the comfort layers and how suitable they are for your comfort and support needs and preferences are very important and the knowledge, experience, and guidance of the manufacturer or merchant you buy from … especially online … is one of the most important parts of a mattress purchase.
Your own personal testing on the two different materials will tell you which you prefer and can also give you some guidelines about the specific types and layering of each that may be most suitable for you.
I would also be careful using reviews as part of a decision about the type of mattress that may be best for you. Each person is unique in their own personal needs and preferences. You can see more of my thoughts about the value of mattress reviews in post #4 here.
Knowing the details of the materials in your mattress and your own personal testing along with the knowledge, experience, and guidance of the merchant you are buying from can be a much more effective way to choose the best quality/value and the most suitable mattress for you than the reviews of other people that don’t take all the many differences and variables that may be unique to you into account.
