Laboratory test methods have been established for some of these parameters, such as pressure distribution, skin microclimate, hygiene, edge support, and long-term stability. Other parameters, such as firmness, are more specific to the sleeper. In general, firm mattresses are recommended for stomach and some back sleepers, soft mattresses are recommended for side sleepers, and medium mattresses are recommended for the majority of back sleepers.
Double mattresses are available with a softer and a firmer part, or with adjustable firmness levels, to accommodate sleepers with different preferences who share a bed. In , a randomized-controlled trial found that medium-firm mattresses assessed using the Hs scale from the European Committee for Standardization were associated with less pain;  this study has been cited by clinical practice guidelines on lower back pain.
The term mattress lifespan refers to the duration in which all types of mattress can retain their original support and comfort. A poor quality foam comfort layer can deteriorate noticeably in 1 year, while a quality latex core can last 20 years or more; innerspring cores typically last around 10 years.
The comfort layer is almost invariably the first area to fail, which is why mattresses are often double-sided, to extend the lifespan. A separate topper may be used instead of or in addition to a comfort layer, which reduces wear and is replaceable without replacing the entire mattress. The majority of high-end mattresses have a lifespan of between 7—10 years but it can last beyond 10 years and more depending on the level of care.
In the United States, mattress warranties are typically for 10 years or 20 years, sometimes 25 years, though this specifically addresses manufacturing defects and faster-than-normal deterioration, not expected deterioration with time. In the United States, as of [update] there is a general expectation that mattresses should last about 10 years, and this is the average number of years Americans keep mattresses, though this varies by age group. The mattress replacement cycle is a key driver of income and profits for the mattress industry — a five-year replacement cycle yields double the sales of a year replacement cycle, for instance — so the mattress industry has a financial incentive to shorten the replacement cycle.
An industry-funded study by researchers at Oklahoma State University funded by the BSC  of 59 people with poor sleep who received free new replacement mattresses for their existing mattresses 5 years or older average age 9.
Wear problems occur with most mattresses and can include sagging, mildew , and staining. These are prevented by proper support, rotation and flipping, keeping it dry, and using a mattress pad or protector. Some symptoms of a broken or worn-out mattress include springs which can be felt poking through the upholstery layer, visible permanent sagging or deformity, lumpiness, and excessive squeaking. Mattresses require a solid foundation which does not itself sag — a sagging foundation, such as by weak slats on a wide bed, will in turn cause the mattress to sag.
Consistently sleeping in the same place and body position causes excessive wear, and thus rotating or flipping mattresses is used to reduce this: double-sided mattresses can be alternately flipped width-wise about the long axis and length-wise about the shorter axis , or alternately flipped and rotated; while single-sided mattresses are only rotated, which is simpler but less effective. Foundations should also be rotated, if possible, though less frequently — rotating box springs twice a year is recommended.
While sagging is undesirable, some level of indentation about 8 cm 3. Excessive wear on mattresses can occur when folding and bending takes place, placing heavy objects in one spot, or excess force on the handles, will also cause more rapid deterioration.
Care should particularly be taken during transport or storage. Mattresses require ventilation to remain dry and prevent mildew, and thus should not be placed directly on the floor or on a solid surface — slats or a box spring provide space for airflow, while solid wood or plywood as in cheap bunkie boards does not. Additional ventilation is recommended for natural materials, in which case leaving the mattress “naked” after stripping sheets for example while laundering is recommended.
If a mattress is allowed to become damp, for example by wet cleaning , mildew may develop inside the upholstery; cleaning with a vacuum cleaner or mild surface cleanser and a slightly damp cloth avoids this.
Mattresses absorb fluids and stains readily, notably from nightly sweating which results in a yellow stain , seminal or Cowper stains which are darker,  menstrual fluids which are dark red,  and other bodily fluids in addition to accidental spills. These visibly stain the ticking and seep through into lower layers. In addition to being unhygienic, hard to launder, and unsightly, such stains typically void a warranty.
Thus a mattress protector is suggested to protect the mattress; this can be removed and cleaned separately, and replaced if damaged. Companies often specialize in a particular type of mattress, such as innerspring, latex, and airbed, although as latex and airbeds have become more popular, they have become more common.
Mattresses which are mostly the same are often sold under different brand names;  two of the largest brands, Serta and Simmons , became owned by the same company after a private equity buyout. Another association, Specialty Sleep Association, represents companies such as Innomax and Boyd Specialty focused on latex, waterbeds, and airbeds.
Adjustable beds have become a trend and are more compatible with certain types of mattresses such as latex or memory foam. In the s, affiliate marketing became a major part of the business model for direct-to-consumer online mattress companies such as Amerisleep. Another large company, Spring Air , went bankrupt in and was purchased by one of its former executives. Comfortaire, founded in , was the first to specialize in airbeds.
Pikolin , founded in , is one of the largest manufacturers of mattresses. From Wikipedia, the free encyclopedia. The program includes drawing layout functionality, surface rendering in different “styles”, and enables placement of its models within Google Earth. Google SketchUp Pro 6 introduced a beta version of Google SketchUp LayOut which includes 2D vector tools and page layout tools allowing presentations to be produced without the need for a separate presentation program.
Trimble Navigation now Trimble Inc. A new site was provided, Extension Warehouse, hosting plugins and extensions for SketchUp.
SketchUp comes in three subscription options:   . SketchUp Pro subscription includes the eponymous desktop 3D modeler, plus importers and exporters to common 2D and 3D formats, access to SketchUp’s repository of pre-built 3D models 3D Warehouse , access to its extension library Extension Warehouse , access to LayOut 2D documentation software and Style Builder create custom edge styles for SketchUp models.
Go, formally known as Shop, is a SketchUp offering that includes the following: web and mobile modelers, SketchUp for Web and SketchUp for iPad; Trimble Connect Business, a cloud collaboration tool for viewing, sharing, and accessing project information from anywhere; and access to SketchUp’s model library, 3D Warehouse.
SketchUp Go is aimed at design and construction professionals who are stakeholders in the design, review, and presentation process, as well as for DIY designers. It has a feature set designed to meet the specific needs of users on the go.
For example, users can model and mark up 3D models digitally using Apple Pencil and touch. They can take iPad to construction project sites and coordinate in 3D. Currently, only Pro and Studio plans feature this modeler. Compared to Make, SketchUp Free does not support extensions, creation and editing of materials.
The product is not for commercial use. On June 4, , Trimble announced that SketchUp would transition to a subscription business model. File sizes of the models can be up to 50 MB. Anyone can make, modify and re-upload content to and from the 3D warehouse free of charge. Since Trimble has launched a new version of 3D Warehouse where companies may have an official page with their own 3D catalog of products.
Trimble is currently investing in creating 3D developer partners in order to have more professionally modeled products available in 3D Warehouse. According to the Trimble, 3D Warehouse is the most popular 3D content site on the web. For enterprise support 17 Euro per user, per year, up to 99 users, then discounts apply. Proprietary freemium.
