The mattress needed the first 5 minutes to develop their maximum extent to achieve. That's absolutely fine. The valve closes tightly and there are no leaks. The dimensions in the description match. The mattress is really 200cm long and reaches a thickness of about 3cm. Even small ground irregularities it balances very well. In my estimation, (I weigh 75KG) it is probably for people over 90KG quite a hard matter but that is 3cm thick indeed not surprising. Curled leaves the mattress in just over a minute. It fits comfortably then again in the pannier. Worth mentioning are still the two Velcro strips that are included. Thus the mattress can also fix the rolled up state. However, the thermal insulation is not particularly. Cold floors can be felt thoroughly. But this can be compensated under the mattress either by a good sleeping bag or extra insulation. The pack bag is well made and has enough space for the mattress. Unfortunately it has no shoulder strap.
Conclusion: price-performance ratio is absolutely in order. For occasional campers and people under 90KG a good, solid and comfortable Schlafmatraze. Thermal insulation is unfortunately a small deficit.
