You want to get the best road balance for everyday use? Than 5100 STREET NCO SUSPENSION is a perfect option for you. Maximize grip by controlling rebound and right height of your car. These coilovers include springs and are designed to run OEM top mounts. This AST design incorporates coilovers for the front dampers and maintains a divorced setup, like OEM, for the rear dampers. This translates to a more comfortable configuration that achieves a flawless road balance. Consider this kit features, vehicle specific, fixed spring rates for the rears. The initial setup for setting and spring rates is rooted in our extensive development and testing process. Individual preferences can easily be fine-tuned by making adjustments to the rebound knob or altering the ride height. You can adjust the rebound, means you can control the return to extension of your dampers, enabling you to attain the ideal road balance tailored to your specific requirements. With 12 distinct positions to choose from, each adjustment delivers distinct feedback and a unique driving experience. AST Suspension is a monotube design. This is a benefit for you because these dampers offer a large piston to control the adjustability of rebound damping. There is no aeration or foaming in monotube dampers, this will result in a more responsive valving. AST high pressure dampers will increase performance, when you need it, in various driving conditions. These dampers are rebuildable, which means that if any damage or issues arise, you can have them addressed at a certified AST service center.This Part Fits:

Soft, but pricey, kinda shiny, and retains pet hair/lint
Size: Queen (90" x 90"), Color: Olive Green (No Comforter), Size: Queen (90" x 90"), Color: Olive Green (No Comforter)
So I’ll start by saying that I’ve bought many Bedsure products in the past. This one does not disappoint, but I also don’t feel like it’s 5 stars.
It washed well and feels nice. Overall it’s a great duvet cover, but there’s three things I don’t personally like:
1. The price. Compared to their other covers, this one seems steep (though it’s probably the material that makes it more expensive?).
2. The material is somewhat shiny. I wasn't expecting that, and I don’t dig it. I’ve never had a cover that shines like this one does.
3. Pet hair retention is especially noticeable on this darker duvet (see photo). I’m sure this is either the fabric or the weave that causes this.
For these three things, I’m giving it 4 stars instead of 5. That said, if you can snag this during a sale (and you don’t have pets or don’t mind hair clinging to the cover), go for it!

Yes, it’s organic cotton!
Size: Queen (90" x 90"), Color: Ivory (No Comforter)
Yes, it’s organic cotton!
After buying two other “100 % organic cotton” duvet covers on Amazon that turned out to be polyester/blends, I was happy to find an honest company and product. The duvet cover washes well, had no detectable odor out of the package, and is a good weight. I love the hidden zipper closure and find that it gets softer with use. I hope the zipper stays intact with prolonged use and gentle wash cycle.
Note that I almost bought this in white but realized it’s a different material (bamboo) based on the product description. If you are looking at different colors, check the material carefully before buying.

I am 100% happy with this duvet set!
Size: King (104" X 90"), Color: 02 - Hotel Double Embroidery, Size: King (104" X 90"), Color: 02 - Hotel Double Embroidery
Wow! I am very impressed with the quality of this duvet set. I love the design of the subtle black double Embroidery. I thought it was made very well unlike one other person said in their review. I find it elegant and luxurious to look at and feel. It’s very comfortable and I like 100% cotton. This is a thicker cotton but it’s cool for sleeping. It’s also not too stiff, unless you want that then you can easily iron it to be that way. I prefer it right out of the washer and dryer for a classy but cozy look! They are exactly like a set I’ve had my eye on in a fine linen store in Palm Beach. Exceptional value!

Great quality and less wrinkles
Size: King (104" X 90"), Color: 01 - Hotel White
I love this duvet, the quality is great and the material makes it from wrinkling easily bc it is a thicker quality cotton. I will be ordering more duvet styles from this brand. This would hv been $150 duvet easily from bed bath and beyond for sure. I've bought so many expensive ones and this one is just as good if not better
