Hi railit,
They are the source of any information I have about their mattresses and I trust them and the information they give me completely yes. The non quilted SleepEz special uses a rayon/silica inherent fire barrier instead of the wool.
The wool quilted cover will slightly reduce the amount you sink into the latex (make it a little firmer) and will also provide better temperature control and some of the surface “feel” of a thin wool layer which some people prefer over sleeping directly on the latex. It’s really a matter of preference and your own personal criteria.
Both their organic line and their regular line have the wool quilted cover but the regular gives you a choice between blended talalay and 100% natural Dunlop in any of the layers and has a lower cost while the organic line gives you a choice between 100% natural Talalay and organic Dunlop in any of the layers and is more costly. I personally don’t think organic Dunlop is worth the premium for the certification in terms of performance or safety (see post #6 here) but some people do prefer the 100% natural Talalay over the blended even though they are very similar in terms of feel and performance and all of them have the same OekoTex certification.
The Special has 100% natural talalay in the comfort layer and 100% natural Dunlop in the lower layers. It also doesn’t have the 5% member discount because it’s a lower margin mattress and has a pillow bonus instead.
The comparison between Talalay and Dunlop is also a preference of “feel” (see post #7 here) but Dunlop has a higher compression modulus which means that it gets firmer faster than Talalay in the same ILD as you sink in deeper than the 25% compression where ILD is measured so would generally feel firmer and be more “supportive” (you would sink in less) than Talalay.
