Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.120". 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.

Great Mattress for Everyday Use
Item Firmness Description: Medium Firm, Item Thickness: 6.0 Inches, Size: Twin, Item Firmness Description: Medium Firm, Item Thickness: 6.0 Inches, Size: Twin
I’ve been sleeping on this mattress for a few days now, and I honestly couldn’t be happier with it. It has that wonderfully soft, memory foam feel that I love, but it also provides just the right amount of support to keep my body comfortable all night long. I usually sleep on my side, and sometimes on my back, and I find that it feels great in both positions—no more waking up with a sore back, which is such a relief. What really surprised me is how cool it stays during the night. I’ve used memory foam mattresses before that made me sweat, but this one has a noticeable cooling effect that actually works better than I expected. It stays comfortable all night, no matter how much I toss and turn. Plus, it absorbs movement really well, so if my partner shifts around or I move in my sleep, it doesn’t disturb me at all. Setting it up was super easy—the mattress expanded quickly after I took it out of the box. There was a small foam smell at first, but it vanished pretty fast. Overall, it’s comfortable, supportive, and feels like a great value. If you’re looking for a mattress that strikes a good balance between softness and support, I’d definitely recommend giving this one a try.

Comfortable, Supportive, and Sleeps Cool
Item Firmness Description: Medium Firm, Item Thickness: 10.0 Inches, Size: Queen (U.S. Standard)
This queen mattress is very comfortable and offers a great balance of softness and support. It is medium-firm and works well for relieving pressure on the back, shoulders, and hips while still feeling supportive throughout the night. The cooling feature helps keep the mattress comfortable and fresh, especially for warmer sleepers. It arrived neatly packed in a box and expanded quickly after opening with very little odor. I also appreciate that it’s certified, which gives extra peace of mind about the materials. Overall, a high-quality mattress that delivers great comfort and value for the price.

Amazing mattress
Item Firmness Description: Medium Firm, Item Thickness: 12.0 Inches, Size: Queen (U.S. Standard), Item Firmness Description: Medium Firm, Item Thickness: 12.0 Inches, Size: Queen (U.S. Standard)
I’m really happy with this mattress! From the first night, it felt super comfortable and supportive. It has the perfect medium-firm feel, not too hard and not too soft, which makes it great for a good night’s sleep. The memory foam adapts really well to my body and helps relieve pressure, especially on my back and hips. I wake up feeling much more rested and without soreness. I also love that it has a cooling effect. I usually get warm while sleeping, but this mattress stays comfortable throughout the night. Another great thing is that it doesn’t transfer movement, so if you share the bed, you won’t feel the other person moving around. Overall, this mattress exceeded my expectations. It’s comfortable, supportive, and feels like great quality for the price. I would definitely recommend it!

Comfortable and well made
Item Firmness Description: Medium Firm, Item Thickness: 12.0 Inches, Size: King
The firmness is great. Sleeps so good. Keeps us cool and forms to our bodies. I just hope it holds up for a few years. I have the 12 inch and my daughter that is 100lbs has the 10 inch we’ll see if this was as good of a buy as I think it is. Feels good and soft to the touch. I recommend this to anyone before you spend 2000.00 on a bed try this one it so very worth the money.

Couch yes. Sleep, no
Item Firmness Description: Medium Firm, Item Thickness: 6.0 Inches, Size: Twin
I bought it for a daybed in the livingroom as a couch. It’s firm, but conforms to you(memory foam). Sitting is comfortable, however if I lay down it’s too hard. I can set a plate of food down next to me and it won’t move. So perfect for a couch, I wouldn’t be able to sleep on it
