Tüketicilerin Yatak Seçim Davranışlarının İncelenmesi

Abstract

Özet: Günümüzde insanların hayat standartlarının artmasıyla, günümüzün üçte birini geçirdiğimiz uyku ortamını oluşturan tekstil ürünlerinden beklentileri de artmıştır. Konfor kavramı, giysiler için olduğu gibi yatak mikroklimasını oluşturan tekstil bileşenleri için de önemlidir. Bu çalışmada, bir grup tüketicinin yatak seçiminde önem verdiği parametreler, konforlu uyku için gerekli şartlar, reklamların satın alma davranışları üzerindeki etkileri, tercih edilen yatakların kullanım süreleri, uyku sırasında yaşanan fizyolojik problemler konularındaki görüşleri anket yöntemiyle alınmıştır. Literatürde genellikle belirlenen yatakların sertlik-yumuşaklık algısı, yarattığı sağlık problemleri ile ilgili anketler ve subjektif denemeler mevcuttur. 320 kişinin katıldığı ankette kaliteli uyku için önem verilen parametreler incelendiğinde, en önemli faktörün yatak konforu olduğu, hammadde ve bitim işlemleri ile sağlanan fonksiyonelliklerin de ön planda olduğu tespit edilmiştir. Termal konforun yanında, çoğunluğun hissettiği sırt/omurga ve bel ağrılarına yönelik mekanik desteklerin de yatak tasarımında önemli olduğu tespit edilmiştir. Tüketicilerin yatak tercihinde reklamlardan özellikle ortopedik özellikler, kullanım kolaylığı ve sağlıkla ilgili özellikler konusunda etkilendikleri tespit edilmiştir.Abstract: Nowadays, with the increase of people's living standards, the expectations from textile products constituting sleeping environment in which we spend one third of a day have increased. The concept of comfort is also vital for the textile components that create the mattress microclimate as in clothes. In this study, the opinions of a group of consumers about the parameters that they consider in mattress selection, the conditions for a comfortable sleep, the effects of advertisements on the buying behaviors, the usage periods of the preferred mattresses and the physiological problems during sleep were taken by a survey. In the literature, studies generally cover hardness-softness perception of the mattresses, questionnaires and subjective trials related to health problems. According to the results of 320 respondent; comfort, material and functional finishing applications are the parameters important for a comfortable sleep. Besides thermal comfort, mechanical supports designed to prevent back/spine and waist area pains are important points for mattress design. Moreover, consumers were influenced by advertisements in mattress preference for orthopedic properties, functional properties related to easy care and health issues.

“…The syntheses of 1,4‐diaryl‐2,5‐dihydro‐1 H ‐imidazole 3‐oxides 1 [ 45,46 ] and 4‐phenyl‐1‐aryl‐1 H ‐imidazoles 2 [ 47 ] were performed by following the procedures developed in our laboratory.…”

“…Compounds 1a–d were synthesized according to the literature procedure. [ 47 ] Into the aniline derivative solution (5 mmol) in methanol (10 mL), Na 2 CO 3 (2.5 mmol) and phenacylbromide oxime (5 mmol) were added, respectively, and the mixture was stirred for 25 min at room temperature. Then formaldehyde (5 mmol) was added and stirred for 1 h. In the case of 1d , the mixture was refluxed for 6 h. The precipitated product upon standing in the fridge for 1 h was filtered, washed with cold water and crystallized from ethanol.…”
