Hi hose406,
That would depend on where you are in the “princess/anything” scale.
No … pictures don’t say anything about the materials … you would need to know the actual specifications of every layer in the mattress. If you are working with memory foam you would also need to either buy the same memory foam made by the same manufacturer or have enough information about the memory foam properties (which can be difficult) to try to approximate it with other types of memory foam made by different manufacturers. You can read more about some of the differences between different types of memory foam in post #9 here and post #8 here. Even in the same density/quality different types of memory foam can be quite different from each other.
Depending on whether you choose every layer “correctly” or if one or more need to be replaced … it can end up being more costly than working with a manufacturer that has good quality and value.
You can see the guidelines I use for memory foam mattresses in post #10 here. You can also see my thoughts about buying from Costco in post #2 here and the more detailed post it links to. They are certainly not the best source of quality and value and they also have no idea of which mattresses they sell may be most suitable for different types of people (body types, sleeping positions, preferences etc). At least you get a “free roll of the dice” if you guess wrong though because of their return policy.
As you can see in post #2 here there are too many variables and unknowns for me to help with what to choose but I’m happy to help with how to choose.
Post #1 here is always the best place to start and has the basic information steps and guidelines that can help you make the best choices.
Post #12 here has some of the better online memory foam options that I’m aware of if that is the direction you prefer to go. There are are some good quality mattresses available there that are inside your budget and you would have more knowledgeable and experienced people available to help you with your choices as well (and some of them have a similar “feel” to some of the Tempurpedic models that your can test locally to get a sense of what they would feel like)
If you let me know your city or zip I’d also be happy to let you know of any local options or possibilities I may be aware of in your area.
