COMP Cams Valve Locks Eb 5/16in 7Deg - Set of 100Most people believe that the tang inside a valve lock holds the retainer and valve spring in place while the engine is running, but this isn't the case. The cross section of material in the tang is not strong enough to withstand open spring loads of 1000 lbs. or more. The sole purpose of the tang is to temporarily locate the lock, retainer and spring relative to the valve until the taper of the retainer can nest around the outside surface of the lock.

I ordered this mattress topper for our guest bedroom. It is soft and adds a little plushness to the existing mattress. I ordered the queen size for our queen size mattress. It fit well, without much overlap from the mattress topper. The topper has elastic corner bands as well as the fitted sheet like band around the edge, so the topper should stay in place. The color is black, as shown and if you use light colored sheets, it will likely show through. To combat this, I used a white mattress protector overtop of the pillow topper. You cannot see it through our protector and white sheets. The topper is more like a padded mattress protector than a true topper. It reminds me of a pillow top, it's not foam just filled to add softness to the mattress. I think it's a great addition, it adds a little height and comfort to the mattress. Overall, I think this is a nice upgrade to our guest room. It fits well, and serves its intended purpose. I would recommend to anyone wanting to improve the comfort of their mattress.

Try it but have lower expectations

Color: Black, Size: Queen

Pros: -fairly heavy -fits right -soft enough to dream on -not too expensive Cons: -kinda lumpy feeling and that’s hard to shake -not the classiest wrap/attachment -a little stinky out of the box that can take a while to offgas or whatever It definitely upgrades a futon mattress, even if it doesn’t want to bend easily with it. It’s meant for a stationary mattress.

Feels Like Sleeping on a Cloud

Color: Black, Size: Queen

This mattress topper completely transformed my bed. From the first night, I noticed how much softer and more comfortable my mattress felt. The pillow-top design adds a plush layer of cushioning without making the bed feel overly soft or unsupportive. I was especially impressed by how breathable it is. I tend to get warm while sleeping, but this topper stays comfortable throughout the night and doesn’t trap heat. The moisture-wicking fabric is a nice bonus and helps keep the bed feeling fresh. The deep-pocket design fit my mattress perfectly and stayed securely in place without shifting around. Installation was quick and easy, and the black color gives it a sleek, premium look. After fluffing up, it provided just the right amount of extra comfort and made my mattress feel much more luxurious. For the price, this topper offers excellent value and has greatly improved my sleep quality. I would definitely purchase it again and recommend it to anyone looking to add softness and comfort to their bed.

Feels Like Sleeping on a Cloud — One of My Favorite Bedsure Products Yet

Color: Black, Size: King

I’ve had really good experiences with Bedsure products over time, so whenever I get the chance to try another one I usually do, and this mattress topper definitely did not disappoint. This one went on my mom’s king size bed and the difference was noticeable immediately. The topper has a soft, cloud-like feel while still giving enough support underneath so you don’t just sink straight through it. It added a much more comfortable layer to the mattress and made the bed feel cozy and inviting without being overly heavy or hot. I also appreciated how easy it was to put on. The deep pocket design fit securely over the king mattress without struggling to stretch the corners, and once it was on, it stayed in place well through the night. The material feels breathable and smooth, which is especially nice for warmer nights. My mom commented that she slept really well with it and woke up feeling more comfortable than usual, which honestly says a lot. Overall this feels like a high-quality mattress topper that makes a bed instantly more comfortable. Bedsure continues to be one of those brands I trust for soft bedding and reliable quality.

Not Worth the Price

Color: Black, Size: Queen

I expected more. The images are a bit misleading with the amount of fluff and thickness the product actually has. Despite following the instructions, it’s pretty flat. It had a funky chemically smell to it, so I sprayed with some Febreeze. Honestly in my opinion I don’t think it’s worth $60. I think if you want something similar, go to Marshals or TJ Maxx.
