120x140x12 Double Lip Nitrile Rubber Rotary Shaft SealAcrylonitrile butadiene rubber (NBR) is the material name for nitrile rubber. This material is very good for seals due to its make up. Nitrile rubber can tolerate short term dry running of the sealing lip. The operating temperature range without failure of nitrile rubber is 40 to +100 C. This also offers a special nitrile rubber compound with a temperature range between 55 and +110 C. Please click here for a full in depth look at the range of seals

Pillows come overstuffed so you can adjust the amount of foam and support. I took extra foam out for use in other pillows or for comfort adjustment. Outside of pillow is washable and just zips to get on and off. Inside of pillow also zips for easy access to foam. Pillow is great for head and neck positioning for optimal posture, alignment, and unloading of weight on neck and shoulders for muscle relaxation and pain relief for deeper sleep.

Good quality and adjustable comfort

Size: Queen (Adjustable Foam)

Well-constructed and packed with lots of foam pieces. As received, the pillow is firm and well stuffed. I would up removing a good amount of stuffing for a custom fit -- as recommended by the pillow maker. Now, the pillow is extremely comfortable. Due to being able to customize the fill and making this pillow comfortable to my sleeping style, I am happy with this purchase and would recommend its purchase.

I like it

Size: Queen (Adjustable Foam)

I have been trying to find the "perfect" pillow. I am not sure if this would count as the perfect pillow, but it is better than my previous pillow. I have not been waking up with a stiff neck and soreness across my shoulders. It is more firm than I thought it would be. But so far, so good.
