A good, sturdy product, relatively well designed. It has some lumbar support, although not as it should have. The material is good, assembly is easy, but… this is where the less good points begin. It is too heavy, but I understand that robustness has a cost. The buckles are made of brittle plastic, when they could have been metal (one broke when trying to pack it, on the first try, in fact). Packing it in the case too tightly, without any additional space, forces us to cram the textile part as much as we can. All in all, though, I recommend this model. It is sturdy and comfortable enough. Portability is not exactly its strong point.
