Hi yashax,
These would both make great quality/value choices and they have many similarities as well as some differences between them.
The Aloe Alexis is a latex/polyfoam hybrid and the SleepEZ 10000 is an all latex mattress (see post #2 here) but the Aloe Alexis has two layers of latex instead of one so it would be closer to the feel and performance of an “all latex mattress” than other latex/polyfoam hybrid mattresses that have thinner layers of latex on top of the polyfoam (see post #2 here).
The SleepEZ 10000 has 3 separate layers that can be re-arranged or exchanged while the Aloe Alexis has 2 so the SleepEZ 10000 has more options to customize the layering after a purchase.
SleepEZ has the option to choose between 100% natural Dunlop or Talalay in any of their layers and the Aloe Alexis uses Talalay. There is more about some of the general differences between Talalay and Dunlop in post #7 here but the choice between them would be a preference choice rather than a “better/worse” choice.
Brooklyn Bedding has more firmness choices available for their individual layers than SleepEZ.
The covers are also different and the SleepEZ uses a wool quilted cotton cover and the wool is used as the only fire barrier while the Aloe Alexis has both polyfoam and wool in the quilting. There is more about quilting layers and materials in post #12 here.
When you are down to finalists that are all choices between “good and good” and there are no clear winners between them then you are in the fortunate position that any of them would likely be a suitable choice and post #2 here can help you make a final choice based on your local testing, your conversations with each of them, your confidence about the suitability of each one, the prices, the options you have after a purchase, and on “informed best judgement” based on all the other objective, subjective, and intangible parts of your personal value equation that are most important to you.
