Comparison Intex 66928 vs Bestway 67225

The maximum weight for which the mattress is designed; in models with 2 or more seats, the maximum total weight of all people on the product is assumed.

It is definitely impossible to exceed the weight limit: even if the shell does not burst immediately, this can happen at almost any moment. But the load margin will definitely not be superfluous — it will give an additional guarantee in case of unforeseen situations. As for specific values, in the most “delicate” modern mattresses, the allowable weight does not exceed 150 kg, the values \u200b\u200bof 151 – 170 kg and 171 – 200 kg can be classified as average, and the most durable and reliable products can withstand more than 200 kg.

Also note that this parameter is indicated for normal working pressure; if the pumping is too strong or too weak, the voltage experienced by the sheath may be higher than the calculated one even at a load not exceeding the maximum allowable.

The number of air chambers — separate compartments filled with air — is provided in the mattress design.

The simplest option in this case is one common compartment for the entire shell; however, nowadays, you can also find multi-chamber products. Most often, this arrangement is associated more with the specifics of production than with practical utility. For example, in a mattress chair (see "Type"), it is more convenient to make the main shell and backrest in the form of two separate chambers; an inflatable raft in the form of an animal (see ibid.) may have wings or fins in separate compartments, etc. However, sometimes several chambers provide quite practical advantages. So, in traditional mattresses, a separate compartment is often provided for a headrest (see "Functions and Capabilities"); this, among other things, allows you to adjust the degree of inflation and stiffness of the headrest separately, independently of the rest of the surface of the product. And in the same inflatable rafts, in addition to the main shell, an inflatable bottom can be provided — it gives the product additional rigidity.

Also note that the presence of several air chambers provides a certain degree of additional safety when used on the water: in the event of damage, the air escapes only from the damaged compartment, and the mattress remains afloat.

Additional functions and equipment elements provided in the mattress design. These range from universal features found on all types of mattresses, such as a headrest or carrying handles, to specialized accessories such as flocking, leg openings, cup holders, or perimeter ropes. Here is a more detailed description of the different options:

— Flocked coating(velor). A special velvety coating applied to the surface of the mattress. It is a characteristic feature of models for relaxation (see "Type"): thanks to this coating, the sheet does not slip off the mattress, and if desired, you can rest on such a product without a sheet — the velvety surface is quite pleasant to the touch and comfortable even when you stay on it for a long time. But for mattresses used on the water, such an addition will definitely be redundant — especially since velor does not tolerate prolonged exposure to moisture.

— Headrest. A special device for the head of a person lying on a mattress. The specific design and purpose of the headrest may be different, depending on the type of product (see above) and some other features. So, in models for rest, it looks like a thickening in the head of the mattress and is intended mainly to complement the pillow; however, there is another optio...n — a folding non-removable pillow, which in this case is also considered to be a headrest. In swimming mattresses, the head support is often made in the form of a separate compartment and can also be used as a pillow. Among other things, by changing the degree of pumping, it is possible to adjust the rigidity of such a compartment, regardless of the main part of the product; in addition, in many models, the headrest is connected to the rest of the mattress by a flexible bridge and can deviate to a certain angle — this allows you to change the height of the “pillow” by placing various objects under it. And in some mattress chairs, the function of the headrest is actually performed by the back (although another option is more common — the back, supplemented by a clearly defined additional support for the head). Anyway, this design feature can provide additional comfort, but sometimes it can be unnecessary — for example, for those who are used to sleeping on low pillows, a headrest in a relaxation mattress can create inconvenience.

— Hole for legs. A feature found exclusively in "water" mattresses. Such a hole allows a person sitting or lying on a mattress to lower their legs into the water; this not only provides comfort in hot weather, but also allows you to control the movement of the inflatable "watercraft" to a certain extent.

— Cup holder. A special recess (or several recesses) where you can securely place a glass or a bottle / can of a drink. Such equipment is most popular in mattress chairs, and some models of inflatable rafts are also equipped with cup holders (see "Type"). But in more traditional products designed for the recumbent position of the user, this feature is practically not found — primarily because it is simply inconvenient to drink lying down.

— Carrying handles. Special handles that make it easier to carry the product in the inflated position. They are found mainly among mattress chairs and inflatable rafts (see "Type") — the rest of the types of "water" mattresses are for the most part quite convenient to carry and without handles, and recreational models are supposed to be transported deflated and inflated directly at the place of use .

— Rope around the perimeter. Relatively thin, but strong rope, fixed around the perimeter (circumference) of the product. It is found exclusively in models for water — mainly among mattress chairs and inflatable rafts (see "Type"). The rope in such cases performs several functions at once. Firstly, it allows a person in the water to securely hold on to a floating structure. Secondly, such equipment makes it possible to easily fix the product near the shore, the side of the boat, etc. Thirdly, the rope can be useful when catching a “runaway” mattress — for example, if it has been blown away from the shore by the wind.

Dimensions of the mattress in the working (inflated) position.

Features of the choice according to these parameters depend on the type of product (see above); the length is usually the most important. So, a mattress for rest should ideally be somewhat longer than the user's height (at least 20 cm); so most of these models are made in length 180 – 200 cm, or even more. Bathing mattresses can be comfortably used even with a relatively short length — it can even be slightly less than the user's height; therefore, such models are generally shorter. In chair mattresses, this size often does not exceed 180 cm — in the expectation that a person's legs may well protrude beyond the limits of such a product; and inflatable rafts are mostly made short (although there are exceptions here and there).

In turn, the width is primarily related to the number of seats. So, a width of 80 – 100 cm or less is only suitable for single models. Among products where this size is 100 – 120 cm, there are also double solutions — however very specific, namely, mattress chairs in the shape of a figure eight. A width of 120 – 140 cm can already have double mattresses in a classic format (including models for relaxation), but they are mainly suitable...for people of a thin build. For larger users, larger sizes of 140 – 160 cm or more are recommended.

As for the thickness, this is generally an auxiliary parameter — it is extremely rarely necessary both for selection and for use. We only note that in mattress chairs (see "Type") this size often means exactly the thickness of the main surface, and not the size of the structure in height (the height is noticeably larger, since it takes into account the presence of a backrest, headrest and/or bending of the main surface. It is also worth mentioning that thick home mattresses are already classified in another category of goods — inflatable furniture (such products are called air beds).

The total weight of the mattress The lighter the product, the more convenient it is to carry; at the same time, thinner materials are often used to reduce weight than in similar models, which accordingly affects both the maximum load (see above) and overall reliability.
