Permissible weight
The maximum weight that the rug can carry without consequences. This parameter is relevant primarily for inflatable and self-inflating products (see "Type"), because mats, due to the dense structure of the material, are highly resistant to loads, and it is almost impossible to overload such a mat during normal use.
Of course, the permissible load must not be exceeded — this can lead to damage to the rug. However, it should also be borne in mind that its value is usually indicated for situations where the weight is distributed more or less evenly over the surface; under point loads, the product can be damaged even by a weight that is less than indicated in this paragraph. To put it simply, if a full-size “sleeper” model (see “Type”) has a load capacity of 100kg, a 95kg hiker can comfortably lie on such a mat, but trying to stand up with their feet can end up sad, since the load at the point of contact will be much higher than calculated.
Qty. valves
The number of valves for inflating and releasing air provided in the design of an inflatable or self-inflating product (see "Type").
— 1. One valve used for both inflating and deflating the mat. The advantages of this option are simplicity and low cost. On the other hand, the throughput of valves is in most cases low; this is not a serious disadvantage when filling the mat with air, but can greatly slow down the folding.
— 2. The features of this option depend on the number of seats (see above) for which a certain model of the rug is designed. So, in single equipment each valve has its own specialization. One is designed to inflate and is often designed to prevent air from escaping even when the plug is open; the other, which is responsible for the release of air, has a high throughput and allows you to quickly blow off and roll up the product. However such models cost more than similar single-valve ones. And double mats usually consist of two separate halves, each of which provides its own universal valve; in terms of inflation / deflation, they are no different from the single-valve models described above.
- 4. Four valves can be installed in two-seat models: each separate half of these mats has an inlet and outlet valve, similar to single-seat two-valve products (see above).
Fastening possibility
Possibility of connection with other rugs in a single design. Thus, for example, you can create a family bed from two products, or an impromptu game table for the company. However not all models with this function are compatible with each other — by definition, quilting is available for the same rugs, but the compatibility of different models should be clarified separately.
Repair kit
Minor repair kit, originally supplied with the mat. This option is found exclusively among inflatable and self-inflating models: even a slight damage to the shell can completely render such a rug unusable. In such cases, a
repair kit allows you to correct the situation: such a kit includes at least patches (with special glue or self-adhesive ones), and sometimes additional tools. Note that repair kits are usually designed for minor damage — cuts and punctures up to 10 – 15 cm in size; however, more serious "accidents" do not happen so often.
Dimensions (folded)
Dimensions of the rug when folded. This parameter determines how much space the product will take up during transportation. Note that in this case, “perfect” sizes are usually indicated, corresponding to the most dense packaging according to all the rules; actual dimensions may be slightly larger, depending on the quality of folding.
