The product presents no chemical smell compared to other products is a winning star. The frame is rustproof another point won and the depth adjustment to adapt to the thickness of the radiator and a shank is provided for holding the armature and the spacing would be if the latter were more coat of protection: foam, or other heavy fabrics. For against which removes 2 stars the armature not being bend at once requires uncomfortable fittings such as bolts. The fabric is fine (I just have about 1 month) and steady seems to me .. The retained tissue above the radiator impede the passage of heat and which I was forced to fold. The size is for an average cat but not for it goes a little more. A hammock that does not exceed half of a large heatsink is also good. Thank you for your attention.
