Headrest
The presence of a
headrest in the product is a device for supporting the head.
This feature is found mainly among beds (see "Type"). In such furniture, the headrest is a small protrusion from the side of the head of a lying person (people). This ledge performs several functions at once: it increases the height of the pillow, reduces the likelihood of it falling over the edge of the bed, and in extreme cases it can even replace the pillow. At the same time, note that in some cases the headrest may be redundant — for example, if the existing pillows are already of considerable thickness. So most air beds do not have such equipment.
Size (unfolded)
The overall dimensions of the product in the working position — fully inflated, and for folding models (see "Type") — also unfolded.
In general, this is a fairly obvious parameter; we only note that the size of the space available for sitting or lying down may be somewhat less than the overall length or width of the product — due to the presence of a backrest and/or armrests. These elements usually account for about 20 – 25 cm of space.
Weight
The total weight of the product.
The ease of transportation depends primarily on the weight. However in the case of inflatable furniture, this point is not critical: most of these products are still designed for constant use in one place. However, sometimes a piece of furniture is also bought with the expectation of being able to quickly move from place to place — for example, from home to the country house and back. In such cases, it is worth considering that light weight makes it easier to carry, but for the same performance, lighter products usually have either less reliability (due to the thin shell) or more cost than heavier ones.
