ILD numbers generally range from 15 to A quick note, many people believe that the harder a foam feels, the longer it will last. This is a common misconception.
Super hard foams at an ILD of 60 can come in 4. The higher density foam always lasts longer. Memory foam came on to the scene from a more unlikely source: NASA. Scientists began to develop this new foam as a way to reduce the strain and stress on astronauts as they took off and re entered Earth's atmosphere.
While NASA led the charge in this new industry, it proved too costly at the time. Around the 's, foam manufacturers gained access to the information and refined the formula to make it more cost effective.
Memory foam reacts more slowly. Due to this slow reaction, memory foam provides more pressure relieving properties. When placed in the top, or comfort, layer of the mattress, this allows a softer, more comfortable feel for many people. A quick note, finding an entire memory foam mattress is very difficult. Most manufacturers do not use that because memory foam does not work well as a support layer.
Most all foam beds use a high density polyurethane foam as the base layer with the memory foam on top. Also, memory foam is more heat sensitive than other foams. This means that as the temperature drops, the harder the memory foam will feel. The reverse is also true that warmer temperatures create softer feeling foam. This is due to the fact that memory foam uses a person's body heat to conform to their body shape. Any ideas of where I can buy furniture?
I had a custom upholstered bed frame made by Ekla and it came out beautifully — I sent her a picture of what I wanted and she made it with non-toxic materials. I also have a chair from Cisco that is very well made. I highly recommend Rowena at Pine Street Interiors to help you with any furniture decisions — she is really on top of all the issues. Thank you, Joy! This came at a perfect time! Trying to find safe alternatives to everthing is so time consuming and frustrating especially when you feel a company is being secretive or dishonest about their products.
Thank you, Erin, for your feedback. Your comment came in at the right time too. There is a post in the making. Talk to you soon! Interesting article. I imagine this is toxic to young children, and, if so, why are companies allowed to use such a material in toys made for children? Hi Kara, I completely understand your concerns. Unfortunately, in the US, it is up to us consumers to protect ourselves from toxins. Here is an article I wrote that will help you understand the US system in regard to toxic chemicals.
I encourage you while doing your best to reduce exposure to toxins, remember not to stress out as stress can more harmful than toxins. Yes, it is best to get stuffed animals made of certified organic cotton, at least in the first year of life. But I always ask what is used instead.
And really get answers. I hope you will join my blog. And surely, EVA was tested a few years ago and found to have formamide, which is a carcinogen.
So it is best to avoid it, if possible. Hello, I realize this was posted a few years ago but I have a concern.
I recently bought a used loveseat that emits an oily almost gasoline odor. I just saw in this article that one of the chemicals used to make this foam is a petroleum derivative. Should I just get rid of it? The fabric is made of Micro-Suede.
The only reason I came to know this is from the tag on the chair. NO added flame retardant chemicals. I bought it especially for my 3 and 4 year old great grandkids when they stay the night. I would appreciate any input you can give. Thanking you in advance. Sharon: Health is a complex thing.
Stress is the biggest toxin of all, too. If you do many other healthy things, you can cut a slack. Once achieved, the hair is tightly wound to form ropes, some reaching 80 feet in length, these are carefully placed in a large vacuum tank and steamed. Once removed, it is hung to dry in a large heated chamber where the hair curls naturally.
It remains in this condition for a period of about two months, when it is removed and unravelled. From there it passes through a carding machine, which has several large drums like objects with spikes attached, these pull at the hair and separate and plump it forming it into a light mass.
Today, traditional furniture uses as a second stuffing, normally placed over a fibre base that is covered with scrim, which itself is a strong coarse fabric. Hair will be found in high quality furniture at the upper end of the price range, where, due to its resilience and quality it is used as both a first and secondary stuffing. The main type of feather used in upholstery are down, curled feathers and milled or chopped feathers.
Down originates from duck, goose or swans the latter now being a protected species and is the undercoating found beneath the outer feathers. Because it is soft, it is regarded as the best feather used in upholstery, and is commonly found in cushions and top grade quality furniture. Generally curled feathers are of a slightly inferior quality, they are a combination of poultry and waterfowl feathers. Milled or chopped feather are of a lesser quality and are often used as a filling for mass produced cushions.
During the 18th century, Mill Puff was commonly used as a filler in upholstery and bedding. With the progression of time and inferior grade of cotton wool was used, yet kept the same title. The cotton is produced across Europe, the United States and Australia.
When picked and collected, the cotton balls are processed, first passing through a gin allowing the separation of the fibre from the seed.
The cotton at this stage can be used for spinning, so there is no wastage, the remaining seeds pass through an oil mill and are cleaned, removing any short fibres which remain, these are unsuitable for spinning, it then washes the seed before crushing them and extracting oil from it. The machine used in this process is known as a linter, hence the origin of the name 'cotton linter'. This is a thick padding used in upholstery and bedding, and is generally referred to as cotton felt.
It consists of short cotton fibres that are extracted from the cotton ball. The most common use of Linter felt is as a final layer beneath a top fabric. Woollen felt is effectively produced in the same manner as linter felt, however, the donating animal providing the source material is different. It is a derivative of the fleece from a sheep, goat, alpaca, camel, hares and many other such animal. The majority of the woollen felt used in upholstery is off cuts of other woollen goods and garments, such as clothing and carpets.
The off cuts are first torn, then carded and finally shredded in order to produce the fibrous material for use. It is often formed as a layered filling. In a loose form it is flexible and can be formed into shapes and curves. When a layer of teased cotton is sprayed with starch, it forms a skin over the surface cotton, creating a bond which holds the fibres together, this is known as skin wadding.
It most common use is as a topping over other filling products, such as calico, lined or open horse hair. The skin wadding is remarkably strong and protects the outer surface from protruding hair, and creates a soft comfortable finish. This is formed when various fillings such as, coir, horse hair or fibre are carded and cross laid onto a lightweight hessian base material. This then passes through what is known as a needling machine due to the large quantity of sharp barbed needles it contains, all lined in rows.
The needles move in an up and down motion, forcing the fibres through the hessian on the downward stroke, then release them during the upward stroke, this causes them to penetrate the underside of the hessian only. The following page shows just a small selection of the foams on offer for use in upholstered furniture. These steel wire springs snake in a continuous S-pattern from the front to the back of the frame and are typically tied together like coil springs , although there is less tying involved than when using coils.
While most serpentine springs are made of steel wire, some high-quality furniture manufacturers use copper-coated springs to prevent corrosion. Serpentine springs require much less space in the frame of a sofa or armchair, making them a popular choice for modern furniture makers with sleek designs.
