Hi Julie777,
I’m assuming that you’ve read the mattress shopping tutorial here but two of the most important links in the tutorial that I would especially make sure you read are post #2 here which has more about the different ways to choose a suitable mattress (either locally or online) that is the best “match” for you in terms of “comfort” and PPP (Posture and alignment, Pressure relief, and Personal preferences) that can help you assess and minimize the risks of making a choice that doesn’t turn out as well as you hoped for and post #13 here which has more about the most important parts of the “value” of a mattress purchase which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists (based on all the parts of your personal value equation that are most important to you).

The only way to tell the difference between them in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) or how they will feel for you will be based on your own careful testing (hopefully using the testing guidelines in the tutorial) or your own personal sleeping experience.
Outside of PPP … the most important part of the value of a mattress purchase is durability and the durability and useful life of a mattress depends on its construction and the type and quality of the materials inside it regardless of the name of the manufacturer on the label so I would always make sure that a retailer or manufacturer you are considering is willing and able to provide you with the information listed here so you can compare the materials and components to the quality/durability guidelines to make sure there are no lower quality materials or weak links in a mattress before making any purchase.
I would avoid the Ikea memory foam mattresses because the 3 lb memory foam they use is a lower quality and less durable material that would be a weak link in the mattress.
If you can find out all the information about the layers inside the Allure that you will need to make an informed choice (in the first link) and post it on the forum then I’d certainly be happy to make some comments about it and the mattress as a whole. Without this information it’s not possible to make any comments about the quality or durability of any mattress.
The Rest Therapy is made by Primo International which is a Chinese manufacturer (see post #6 here) and it will most likely contain 3 lb memory foam as well.
If you are looking at online options then some of the lower budget options that may be worth considering are listed in post #4 here.
There may also be some good options available to you locally (that you can test in person) and if you let me know your city or zip code I’d be happy to let you know about any of the better options or possibilities I’m aware of that are close to you.
