# VR and AR in sleep system consulting Technology and future Spatial effect can be shown; lying feel requires real forces Virtual Reality and Augmented Reality can depict a bed in a room, convey size ratios, and make design variants comparable. However, an ordinary headset does not create a realistic pressure distribution under the whole body. The sensation of lying down arises from forces, deformation, temperature, friction, and movement. This analysis separates visual simulation, the influence of expectations, and genuine haptic feedback. For STOLL, the most compelling application lies in the combination of virtual room representation and a real lying test. ## What information visual systems provide AR can overlay a to-scale bed model into an existing room. VR can show various environments or perspectives. This allows, for example, proportions, access, and design variants to be discussed. Accuracy depends on model dimensions, tracking, scale, and representation. Colours and materials do not necessarily appear in the headset or on the screen as they do in real light. The perceived room size can also be influenced by display conditions. A simulation is therefore a planning aid, not a replacement for all physical samples and measurements. ## Why lying sensation is a different task When lying down, body weight is distributed over a large area. The support deforms over time and influences posture as well as the effort required for movement. A handheld controller with vibration does not map this full-body mechanics. Even a haptic glove can only represent a mattress to a very limited extent. Research into the perception of softness shows that visual and tactile information interact. [1] This does not mean that sight can completely replace touch. A convincingly soft-rendered bed can alter expectations while the actually felt support remains unchanged. ## Haptic research and its transferability Experiments investigate how visual expectation and tactile feedback influence the perception of softness. [2] Other works compare real products, VR, and VR with passive haptic elements. [3] Such approaches show that appropriate physical feedback can be relevant. For a mattress consultation, however, a haptic platform would have to adequately reproduce forces and deformations across the body. In addition, there is temperature, surface, and movement. A small laboratory task using a finger or a single object is not a validation of the full-body simulation of a bed. The limit of transferability must remain visible during the presentation. ## Sensible combination in the store Our own recommendation is a real test area with a changeable visual environment. The customer lies on an actually existing mattress and sees different room designs. In this way, the effect of the environment can be explored while the mechanical experience remains real. The order should be chosen deliberately. A first impression of lying down without immersive staging can serve as a reference. Subsequently, the virtual environment shows how design and expectation change the experience. The result is described as an overall experience, not as proof that the same mattress has objectively become softer. ## Compatibility, accessibility, and purchase decision Headsets can be uncomfortable for some people or trigger dizziness. A consultation must remain possible without VR. For elderly or mobility-impaired individuals, safe sitting and lying positions as well as assistance when sitting up are important. Personal room recordings may also contain private information. A good application shortens uncertainty regarding dimensions and design without creating new hurdles. Purchase satisfaction, incorrect orders, and comprehensibility are sensible endpoints. An impressive demonstration effect alone does not yet show a better consultation benefit. ## Visual expectation can influence real assessment A luxurious virtual environment can lead to the same support being assessed differently. This is an interesting perceptual effect, but not a change in its mechanical properties. A consultation attempt should therefore distinguish between room effect and material effect. A first test without an immersive environment can serve as a reference. Afterwards, room variants are shown and the assessment is collected again. The comparison helps to understand what contribution design makes. It must not be presented as proof of a true-to-life simulation of other mattresses as long as the real support remains unchanged. ## Hypothetical case of a virtual hotel room A customer lies on an existing mattress and sees a quiet hotel room with a sea view through a headset. They describe lying down as more relaxing. This impression can arise from the environment even though the pressure distribution is unchanged. The experience can be valuable for the design of one's own bedroom. For the choice between two mattresses, both must nevertheless be tested in reality. STOLL can use the VR experience as a supplement and clearly state what information it provides. The combination of visible atmosphere and real haptics is more honest than the promise that the headset could generate any arbitrary lying sensation. ## Measurable consultation benefit A successful VR application should achieve more than short-term enthusiasm. Sensible goals are a better understanding of size, fewer false assumptions about the room effect, and a more suitable purchase decision. These results can be checked after the appointment and after delivery. Additional time expenditure, discomfort, and the exclusion of certain users also belong in the balance sheet. A conventional alternative remains necessary. Technology improves consultation when it reduces concrete uncertainty and makes the decision more comprehensible. AR in one's own room | Shows size and position | Check scale and real dimensions VR environment | Shows atmosphere and variants | Can influence expectations Passive haptics | Real object complements representation | Must fit spatially and materially Real lying test | Captures full-body contact | Remains important for firmness and movement Dimensional accuracy | Comparison with real dimensions | Make tracking errors visible Comprehensibility | Tasks in a consultation context | Do not just query enthusiasm Purchase decision regarding comfort | Before and after VR | Recognise the influence of expectations Tolerability | Dizziness and termination | Offer an alternative without a headset A dedicated pilot study compares normal consultation, AR room planning, and VR with a real lying test. The groups receive the same product information and sufficient time. Primarily, comprehensibility, the fit of the purchase decision, and subsequent satisfaction are investigated. In contrast, the accuracy of a claimed lying simulation would have to be validated against real mattress judgments. Room effect and mechanical effect remain separate endpoints. Terminations due to discomfort and additional time expenditure are part of the assessment of the overall benefit. STOLL can use AR for proportions and VR for atmosphere. Firmness, pressure, and mobility continue to be tested on real systems. An honest explanation is: 'You see the bed in a different environment and feel the actual support.' A headset alone should not be offered as a true-to-life simulation of any arbitrary mattress. ## Screen only Room and product shape can become visible. Full-body forces are not generated. ## VR on a real bed The environment can be changed. Perceived mechanics still stem from the real bed. ## Haptic platform Can replicate certain forces. Mattress-specific accuracy must be validated. [1] Visual and haptic integration in the estimation of softness https://pmc.ncbi.nlm.nih.gov/articles/PMC4129386/ Experimental perception research.

This paper is a targeted narrative research as of 30 September 2026. The starting point is the specific topic question, scientific publications, and, for technical or legal questions, the relevant original sources. The Word documents provided by the client serve as templates for the professional structure and comparative presentation. Their individual statements have not been adopted without verification. This research is not a systematic comprehensive survey, a meta-analysis, or a product certification. The sources were checked via accessible publication sites, bibliographic datasets, and available excerpts. A complete article was not accessible for every source. Where only an abstract or excerpt was available, the description is limited to the information discernible therein. Figures are only mentioned within their study context; missing details are not supplemented. A phrase such as "no reliable evidence identified" describes the result of this targeted research and does not prove that no such work exists worldwide. The source numbers in the text refer to the list at the end. Directly examined findings, mechanistic considerations, and the author's own practical deductions are linguistically separated. Hypothetical cases illustrate the decision-making logic; they are not documented customer experiences. The suggested test plans are original designs. They do not establish a binding standard or a medical treatment process. Statements about a product class are not automatically transferred to individual models. For classification, the primary criterion is whether the source examines the exact question asked. A technically precise material measurement can be highly informative for a material property while saying little about sleep or long-term health. A clinical study may show a relevant benefit, but only for the group of people, construction, and duration of use studied. Proximity to the concrete question is therefore just as important as the study design. Subsequently, comparison conditions, sample size, observation duration, and potential biases are considered. Blinding is often difficult with bedding. Expectations, habituation, and the sequence of tested variants can influence results. In the case of manufacturer funding, transparency and independent replication are particularly helpful; funding alone does not decide for or against the validity of a finding. Small pilot studies are primarily used to formulate a question more precisely and to plan a larger trial. Statistical significance is not the same as practical importance. A small difference can be mathematically detectable without having a tangible benefit for the person in question. Conversely, a relevant individual improvement may remain statistically uncertain in a small group. Therefore, effect size, uncertainty, and everyday relevant endpoints are assessed together. A blanket score would obscure these differences. The interactive companion page consequently does not use fabricated health scores or simulated figures that appear like measured material data. For implementation, a concrete goal is first defined, and then the smallest reasonably testable change is selected. The initial state, construction used, and observation period are documented. Feedback should capture both the desired benefit and possible new disadvantages. If several components are changed simultaneously, the attribution of success remains uncertain. An individual comparison can improve personal selection but does not replace a general efficacy study. A supplier proof should concern the model actually offered and the intended use. Deviations in the cover, topper, base, care, or software can alter the transferability. The consultation openly states such limitations and formulates only the performance covered by data or immediate observation. For medical or legal questions, the relevant professional assessment remains necessary. The practical recommendation of this document is a basis for decision-making and not an individual diagnosis.
