Bonded foam can also be called foam of foam. What this means is that bonded foam is made by crushing many types of foams and compressing them together with latex which holds the foam together. Bonded foam mattress is good for back pain as it is hard and does not let you sink inside the mattress. It only provides support to your back.
The traditional method of making bonded foam involves re-using the foam of old mattresses that are picked up from the dump. This foam is crushed, and bonded foam is made. This raises many health concerns as the scrap might contain garbage like polythene, slippers, etc. that are crushed in the process and is bad for health. GODREJ ® on the other hand uses virgin(new) foam to make bonded foam which makes it better than the rest. This surely increases the price but keeps health first.
Memory foam is a foam that has some retention capacity and hence it has been called memory foam. Memory foam is special as it rises slowly when pressure is released. This will give you the feeling of being hugged and comfort comes with the package. Some people question, “Are memory foam mattresses better than spring”, but there is no correct answer to that. It depends on the user. For example, if asked whether football is better or cricket is better, then there is no definite answer. Of course, I have my own opinion and I feel that memory foam is better than pocket sprung.
Also pillows made of memory foam are available in the market which give a very relaxing feeling to the one using the pillow as the pillow will take the shape of the sleeper’s head, thus relieving them of any discomfort. Memory foam mattress is good for elderly as it will provide support along with comfort.
The property of this foam is unlike any other and for this property to be showcased properly, this foam has to stay on the top of the mattress.
Urethane is an organic compound. When urethane is repeatedly connected, then it is known as Polyurethane. This is the most common foam. Depending on the density it can be hard (high density) or soft (low density). Mattresses that are made of PU foam are relatively cheap. The two variants are also known as HR (High resilience) foam and soft foam. PU foam can be found in car seats, chair seats, and many other similar places. Even the Sponge used in our kitchens is PU Foam.
The shape of this foam is like an egg crate. The main purpose for this shape is to give an acupuncture-like feeling to the sleeper. This helps to release stress from any part of the body. Such a shape gives this foam priority and hence it is the top-most layer of the mattress.
But if this foam stays on top of the mattress and even memory foam is on top, then one would assume that no mattress would have both memory foam as well as convoluted foam. This assumption is true and consistent with the law of common sense 😁
