Understanding Memory Foam

I get a lot of pain in my buttocks when I sit. Your explanation about "body shear" is the first explanation that makes sense to me. Therefore, I am very interested in your MVP office desk chair, with "the molded and contoured seat that is specifically designed to eliminate body shear." However, the reasons you give for using the soft memory foam in the seat make a lot of sense, too. Can you combine these two features? That is, do you sell the MVP chair with the molded and contoured seat that is specifically designed to eliminate body shear made of the soft memory foam? If not, which one would you recommend would be best for me: the chair made with memory foam, OR the MVP molded and contoured seat that is specifically designed to eliminate body shear? Please reply as soon as possible.

Thank you,
Diane


Dear Diane,

The first thing is to give a little background of regular foam so you understand what it is and the various differences. Standard or Regular foam is commonly referred to as HR foam. The HR stands for High Resiliency. This foam will basically push back at the seated user the same pressure as is exerted upon it. So if you push your finger into the foam, applying 3 pounds of pressure, then the foam will attempt to return to its' molded shape and exert the same 3 pounds of pressure against your finger.

Why do we contour HR foam? It is basically compared in the old metal tractor seat format. The metal tractor seats of old were shaped to apply as much contact to the users seat as possible. This helped keep the user in the seat, over bumpy ground conditions, as well as keep the user stable to operate the vehicle better and safely, and lastly it did increase the amount of surface area against the user. A similar application is a ball on a table has little surface contact and a piece of paper is in full contact.

We contour the HR foam to help with spreading out the users body contact, and go a step further in using Super High Quality foam, just like you would have in an expensive automobile. The budget superstores have the lowest grade of foam in most all cases, it is just short of being Styrofoam. As a woman you can compare it to buying diamonds, color, cut, clarity, carrot weight. Poor quality foam bottoms out, and squishy soft foam bottoms out as well.

Memory foam is popular in that it increases the sheer even more. It is more expensive, and since the foam will relax when the user is seated, it does not require as much contour. Contour helps but is not as necessary as HR foam above. Contour helps the user get in the same sitting points consistently. We have some contour in the foam. As in the "finger pressure" as stated above, memory foam which is in reality Energy Absorbing Foam, relaxes when the 3 pounds of pressure is applied, and resists pushing pressure back at your finger. The foams cell structure actually relaxes and this is desirable. When you remove your finger, the foam slowly goes back to its' original molded shape, hence the term Memory Foam. (HR has a memory too, just much faster)

It a nut shell answer Memory Foam is the best, but sometimes is a hard first-sit, as the foam take a few seconds to begin the relax-process. In cold climates the foam is slightly harder, those cold offices in winter, but the users body heat counteracts the cold office air.

We will introduce a new Memory Foam shortly, both anti-microbial, and less resistant to cold office environments.
