Hi HudaThunkit,
Their 100% natural Dunlop uses a continuous pour process but otherwise would be roughly comparable to other types of 100% natural Dunlop that is made in a mold.
How they compare would depend on which mattress you are comparing them to but the main differences would probably be the “feel” (not the quality) of their Dunlop, the firmness levels and layer options that are available, along with the cover materials (which can be a significant part of the cost of a mattress) and of course any of the other criteria of your personal value equation that are important to you. In terms of quality and durability their Dunlop would be closely comparable to other mattresses that used 6" of 100% natural molded Dunlop. They are certainly a good quality/value option. Mountaintop Foam also makes the Dunlop latex that is used in Ikea mattresses (such as the Edsele here which uses a slightly different blend with 85% natural rubber).
