Maximum load
The maximum load allowed for a hammock, in other words, the weight that the product is guaranteed to withstand. Although this limit is often given with a certain margin (assuming that a person can move, swing, etc.), it still cannot be exceeded: even if the hammock did not break right away, this can happen at any moment (even later, at an acceptable load).
Note that for double products (see "Number of seats") in this case, the total maximum load is given. At the same time, the weight in hammocks is distributed evenly, so pairs of people who differ markedly in physique can use them — the main thing is that the total weight does not exceed the permissible maximum.
Rail
The presence of a rail in the design of the hammock.
A rigid rail is used in the suspension system; its purpose depends on the type of product (see above). So, in some classic hammocks, two slats are used — in the head and in the legs. This design is actually a simplified version of the frame: it provides lateral tension to the fabric, due to which the hammock sags less under load than a frameless hammock, its edges do not “envelop” the lying person so much, and the bed retains a rectangular shape. But for hammock chairs, the rail is mandatory: in such products, both edges of the fabric cling to it and the rail is already hung on a tree, crossbar, etc.
Fabric type
The type of fabric used in the construction of a hammock.
—
Fabric. A traditional heavy fabric that gives the impression of a solid surface. The most convenient, versatile and, as a result, a popular type of fabric used in most models of modern hanging furniture.
—
Grid. The surface is in the form of a grid — cells woven from individual threads. The main difference from the fabric lies precisely in the fact that the surface is not continuous. This design is well suited primarily for hot weather — it provides excellent skin ventilation. However a large mesh is not very convenient: the ropes can put a lot of pressure on the body, especially when sitting / lying in one position for a long time, and it’s more difficult to lean on such a surface (for example, with your hand, getting up from it) than on a fabric one. But there are also fine-mesh nets, which in fact are not too different from the fabric.
Size
General dimensions of the product in length and width.
The width of a bed in a hammock usually corresponds to the total width (second number). But the length of the canvas (see below) is, by definition, less than the total length. However, sometimes manufacturers indicate the dimensions without specifying what exactly they are talking about — about the general dimensions or only about the canvas. In such cases, the same length value is indicated in both clauses; if it is not possible to clarify what exactly we are talking about, the product should be chosen with a certain margin (the canvas is usually 10 — 15% shorter than the entire hammock).
Fabric length
The length of the canvas in hammocks and hammock chairs (see "Type"), in other words — the dimensions of the sleeping / sitting place in length. In the first case, the length of the canvas, usually, is less than the total length of the structure, because fasteners are not taken into account in this case. But hammock chairs are usually folded into a "shell", and here it is the other way around — the overall dimensions are less than the length of the canvas.
