![]() Gel-infused foams are increasingly used to mitigate the effects of heat build-up. Upholstery is made from a wide variety of materials, including various polyurethane and other foams, and a range of cotton, polyester, wool, or synthetic fibers. The upholstery layers covering the springs of an innerspring mattress provide cushioning and comfort. The more recent “Marshall” coil or “pocket springs” is a thin-gauge coil individually encased in a fabric sheath, providing better motion isolation. Four different coil types have been developed, including the basic “Bonnell” coil of the late 19th century. ![]() The individual spring coils are joined together by interconnecting wires, which retains the mattress’s general shape. The level of firmness and support provided by the mattress depends on the spring coils’ gauge or thickness. In their simplest form, innerspring mattresses comprise a spring “core” made of steel spring coils, covered by layers of upholstery called “ticking.” This traditional construction style still has a slight but diminishing market edge in North America. Let’s briefly compare memory foam to innerspring types to see if this is the right mattress for you. This guy is a fan on day 1 and he only posted this two days ago (Sept 17, 2020). Update March 17, 2021: Wow, I just noticed that more than 800 people rated this 4.3 on Amazon (see here), which is higher than I expected. Read on to discover some of its features and benefits, as well as any issues to consider before you purchase one. In this article, we’ll look at some of the technology that makes memory foam mattresses like the Nectar so popular. Notwithstanding some advantages to this technology, like cooling gel foam, and drawbacks, like untested warranty claims, memory foam mattresses are increasingly popular and continue to gain market share. Nectar mattresses use memory foam technology, which has evolved since its relatively recent introduction in the 1990s. However, there is an increasing preference for all-foam and hybrid varieties for comfort and individual support. Typically, modern options have been the coiled, innerspring variety. The humble mattress has come a long way since it was stuffed with straw, goose feathers, or horsehair.
