R-value carries the warmth; thickness decides whether your hip lands · review
A 531 g (18.7 oz) mat that publishes both its flat and its inflated dimensions — an honest distinction most listings skip — and no thickness and no R-value.
A weight of 531 g (18.7 oz), a 40D material, an ergonomically shaped outline said to support a natural sleeping posture, inflation by breath, and dimensions given twice: 225 × 70 cm (88.6 × 27.6 in) uninflated and 190 × 60 cm (74.8 × 23.6 in) inflated. A repair kit is in the box.
225 × 70 cm flat. 190 × 60 cm inflated. As the chambers round out they pull the fabric in — 35 cm of length and 10 cm of width, on this mat.
Most listings publish only the flat figure, and a buyer measuring their tent gets a pleasant surprise and a buyer measuring themselves gets an unpleasant one. Publishing both is a small piece of honesty and it is worth noting.
Thickness. Nowhere in the listing. A 531 g mat is thin by definition, but how thin decides whether a side sleeper’s hip finds the ground through it, and that is not a question the page answers.
R-value, with no standard named. ASTM F3340 exists precisely so that figures from different makers can be compared, and there is nothing here to compare.
It is in the box, stated plainly. An air mat is one thorn from useless, and a maker who supplies patches with the mat has thought about the second night as well as the first.
Check 190 cm (74.8 in) against your own height, and plan the warmth around the sleeping bag rather than around the mat.
The American Amazon store returned nothing, so the buy link opens a local search rather than a page that is not there.

Because filling a mat pulls the fabric in as the chambers round out. A mat cut at 225 × 70 cm (88.6 × 27.6 in) flat sleeps at 190 × 60 cm (74.8 × 23.6 in). Most listings publish only the larger number; publishing both, as this one does, is the more useful and the more honest.
For most people up to about 180 cm (70.9 in) tall, yes, with the head on a stuffed jacket or a pillow. Above that your feet will be over the end and on the ground, which is where the missing R-value stops being an abstract question.
No. Not published on the listing — no insulation figure appears in the listing. What the listing does publish instead is the fabric denier: 40D — stated as the material; the fiber itself is not named.
7.8/ 10
A light mat whose dimensions are described more carefully than almost anything else here, and whose thickness and warmth are not described at all. Buy it on the 531 g (18.7 oz) and the 190 cm (74.8 in); do not assume it insulates.
Lightweight trips where 531 g (18.7 oz) and a 190 cm (74.8 in) sleeping length are the specification, and warmth comes from the bag.
