Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.098". Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.This Part Fits:

Flatter than a regular pillow but nice and soft
Number of Items: 1
Is it softer than a typical memory foam pillow? Yes. But it’s also a lot flatter. I don’t find this pillow rebounds very well. It’s good for stomach sleepers but not so much for side sleepers. I’m a 2/3 of the night side sleeper so it’s unfortunately not my magic pillow.

Best pillow for my neck pain.
Number of Items: 1
I've tried so so many pillows to relieve my neck pain at night and this one is the first pillow that has actually worked. I was skeptical at first as this pillow is heavy and dense but one night and I was hooked. I couldn't believe I found a pillow that actually not only was comfortable but also relieved my neck strain. It's worth the cost to now be able to wake up without pain.

Tempur-Cloud Pillow
Number of Items: 1
My daughter has been struggling to find a good pillow that does not hurt her ears. She is a tummy sleeper, as am I. I have also been struggling to find the perfect pillow. I heard about Tempur pillows and thought it a good idea to buy my daughter a pillow for her birthday. It arrived last night. She tried it out during the night. When she woke up this morning, the first thing she said was that the pillow is amazing. It was a good night for her. She said it felt like sleeping on a marshmallow - soft enough to not hurt her ears but firm enough to support her neck. The pillow is very comfortable. 😊

Just ok
Number of Items: 1
This pillow flattens so much I’m not sure if it’s a legit tempur pedic or not. I bought one previously from Tempur Pedic store and the quality is better plus is more supportive. This one is meh . I gave it to my husband, he doesn’t care

Get one but use it on a medium firm mattress, not a firm one.
Number of Items: 1
You need a mattress that is medium firmness to use this wonderful pillow. It gives perfect neck support and I can sleep on all 4 sides with it. My neck/head pain quit first night used it. On a firm mattress it feels too hard and awkwardly cradle l es my head.
