200,000 years ago humans already made their beds, although in their own way. We know it thanks to a remote cave in Africa

We know that bed frames emerged a long time ago. more than 5,000 yearsthat Tutankhamun was buried next to several cots (including one foldable) or that in the Middle Ages it was not unusual for people to sleep in closetsbut… How did our most remote ancestors, the prehistoric humans who spent their nights in caves, manage to rest? Did they have beds? And if so, how were they prepared? Did they do something similar to the sheet changes? A remote cave located on the border between South Africa and Eswatini just cleared some of those unknowns. And their answers are fascinating. The science of sleep. Few things come more naturally and spontaneously to us than sleeping, but that doesn’t mean it’s a simple matter. Not at least for researchers who are dedicated to studying rest from a scientific perspective, psychological and historicalwhich is precisely what a group of archaeologists has done who has examined several remains of beds in Border Cavea prehistoric site located in the Lebombo mountains with an extensive record that spans from the Paleolithic to the Iron Age. Experts have known about the cave for about 90 years and have been excavating it for decades in search of information about our most remote ancestors, but it still has some surprises in store for them. Recently, for example, they analyzed several sediments at a microscopic level that allowed them to identify something curious: six microfacies with remains that tell us about different types of prehistoric ‘beds’. Beds made basically with plants and ash. Why is it important? To begin with, because the remains located by archaeologists in Border Cave cover a very broad period of time. It is known that the cavern was occupied during a period that extends between 220,000 and 43,000 years back. In fact, the remains of beds date back to between 161,000 and 43,000. Some are even older and date back to 200,000 years ago. As if that were not enough, there is another key fact: there are not many strata studied with a level of detail like that of Border Cave. Experts had already analyzed vestiges in Shibhudu or the deposit of Diepkloofboth in South Africa, but the new sediments have allowed them to go one step further and better understand what resting areas were like in Prehistory. Vegetable beds. One of the conclusions reached by the researchers is that the beds were made with herbs Panicoideaea subfamily of grasses. and reeds. With these materials, the inhabitants of Border Cave created different types of ‘beds’, some with patterns very similar to those seen in other sites in Africa and others apparently novel. “We describe six microfacies stratigraphic characteristics identified in the Border Cave deposits, which cover a period between 200,000 and 43,000 years,” the researchers point out in a study published in Journal of Archaeological Science. “Several match those described at Sibhudu and Diepkloof, although with small and potentially significant differences. Three microfacies, associated with more recent ‘grass mats’, have no published equivalents.” The trail of ash. In the cave, archaeologists have not only found remains of plants. They also located ash. Revealing ash deposits under the plant beds that leave behind some interesting ideas and tell us about how they prepared the ‘beds’ tens of thousands of years ago. For example, archaeologists report that thousands of years ago the inhabitants of Border Cave could use ash as a resource to keep their resting areas dry and warm and keep insects away. Another possibility is that they burned old vegetation to add new one, an idea that is not exactly new. “The construction of plant-based beds and their maintenance with the burning and addition of fresh material has received increasing attention in the search for the origins of modern human behaviors,” recognize. Looking at our ancestors. Another telling clue is that not all Border Cave is the same. Archaeologists have seen important differences depending on the age of the deposits, something that can be seen in the burned remains or the concentrations of phytoliths. For example, the more modern ‘beds’, those between 60,000 and 43,000 years old, are less fragmented and also appear to have been less burned and walked on. “New evidence pointing to the deliberate placement of ash on surfaces prior to bed construction is ambiguous, but the creation of beds over existing or purposefully displaced ash deposits was clearly common practice across all occupations,” ditch.

Sleeping in tourist class has been an impossible mission. Some airlines are testing three seats that convert into beds

Traveling in economy class on a long-haul flight usually means accepting a fairly clear toll: sleeping poorly or, at all, not sleeping at all. We have all experienced it, narrow seats, little space to stretch our legs and a posture that rarely invites rest. That discomfort is not a minor detail, it is part of the experience of flying in this segment. And yet, it is precisely there, in this very everyday problem, where some airlines are beginning to explore solutions within the economy cabin itself. If we go to the opposite extreme, we have seen the reference to what it would be like to fly in absolute comfort many times in airline campaigns. The Emirates ad with Jennifer Aniston illustrates this wellgoing from a cabin without notable services to a private suite with a completely flat bed, that is, to the premium end of the experience. The proposal is not limited to improving comfort, it completely redefines life on board. An attempt to make tourist class habitable And at that point is where we begin to see concrete movements. United just announced a proposal of this type with its call Relax Rowan option within its own economic class that seeks precisely to alleviate that problem. The company presents it as a specific row that, once in flight, can be adapted to stretch out or rest with a little more space. The airline plans to launch it in 2027, place it between United Economy and United Premium Plus and progressively deploy it on more than 200 Boeing 787s and Boeing 777 from now to 2030. But the truth is that this idea is not completely new. Air New Zealand has been exploring this concept for some time with his well-known Skycoucha proposal that also starts with a row of seats in economy class. In its case, the system allows the legrests to be raised until they form a continuous surface on which we can stretch. It is not equivalent to a premium cabin bed, but it does offer more versatile space than the conventional seat and the airline itself presents it as a way to gain comfort without paying for a superior cabin. If we go down to detail, the interesting thing is not so much the configuration itself, but what it allows once we are in flight. Both proposals seek to expand the available surface so that we can really stretch out, something that is not usually common for tourists. Air New Zealand specifies that area in about 1.55 meters long and 74 centimeters wideaccompanied by additional bedding, a seat cover and specific belts or restraint systems to use it safely. United, for its part, adds an adapted mattress, blankets, extra pillows and kits designed to make rest more bearable. With all this, the logical question is who is really compensated by this type of option. United’s promotional video gives us an idea. If we travel alone, having all that space gives us a much more usable surface to stretch out. In the case of couples, the idea is to share it in a more flexible way, alternating positions or using it to rest better during the flight. And if we think about families, especially with small children, Air New Zealand considers different configurations. Now, before imagining a perfect rest, it is worth taking into account some conditions. In the case of Air New Zealand, as we have seen, availability depends on the aircraftroute and operational or regulatory factors, and not all configurations are always accessible. In addition, the price is not fixed, since each passenger’s ticket is paid plus an additional cost for this option, while United has not yet detailed prices, although it has indicated that its deployment will be progressive. Taken together, these proposals don’t completely change what it means to fly economy class, but they do introduce an interesting nuance. The idea is not to replicate a first-class suite, but to offer a little more room to rest within the usual limitations. That balance between cost and convenience is what seems to be guiding these developments.
