Five key benefits

  • Adjustable arms: Arm height adjusts so your shoulders and forearms stay supported through the workday.

Product description

The Boss B6566GY-BK Horizontal Mesh Back Task Chair is designed with comfort and ease in mind. Its defining feature is a Synchro-Tilt Mechanism that allows the backrest and seat to tilt in unison, with the back tilting more than the seat for a recline that follows your body as you lean back. The tilt is tension adjustable, so you can dial in how much resistance you feel through the motion.

Beyond the mechanism, the chair is equipped for everyday work. Adjustable arms support the forearms and shoulders, while a pneumatic gas lift makes seat-height adjustment quick and simple. An upright lock holds the chair in a fixed position when you prefer not to recline. The horizontal mesh back keeps airflow moving across your back during long stretches at the desk.

With a 275 lb weight capacity, a 27-inch nylon base, and dual-wheel nylon casters, the B6566GY-BK is a practical task chair suited to a wide range of users. It carries MAS Green certification and meets CA TB117-2013 flammability standards.

Nice mask! Caviar
Scent: PDRN, Size: 4 Count (Pack of 1), Scent: PDRN, Size: 4 Count (Pack of 1)
The first 3 pictures were taken after the first hour and a half. The second 3 pictures were taken at 2 hours. The mask had a hard time dissolving underneath my eyes and around my chin area mostly but everywhere else it hardened within the first hour or so. I will try to wear it for longer than 2 hours next time. To see if that changes, but my skin feels really nice right now. It's a little sticky, but it looks healthy and has a nice glow. Application is easy. I love that its separated into 2 parts. Doesn't fit well around the nose between the eyes and doesn't cover my entire face but its a great mask. I tried the caviar one this time. I have the collagen ones as well but these have better reviews. They seem to work effectively, for a nice glow and self pamper session.

Loved by a skeptic!
Scent: Collagen, Size: 4 Count (Pack of 1)
I hate face masks but I absolutely LOVE this one. I usually get sensory overload from any type of mask very quickly and even if it’s a short one I hate dealing with the pilling or stickiness of the residue after when you put on your face lotion. This one left my skin feeling hydrated and refreshed even though I only wore it for 30 minutes and my makeup was flawless afterwards! I will definitely buy again!

One of the Most Promising NAD Serums I’ve Tried
Scent: Red Effect Serum, Size: 1.01 Fl Oz (Pack of 1), Scent: Red Effect Serum, Size: 1.01 Fl Oz (Pack of 1)
At 52, post-menopausal, with mature dry skin, I pay close attention to ingredients that may support healthier-looking skin over time. I’ve been using topical NAD-related products for a couple of years now, so this category is not new to me. I’ve tried more expensive options, including brands like Aramore, and until recently many NAD-focused products were priced much higher than this. That’s one reason this serum immediately caught my attention. Abib has been around for years and has built a very strong reputation in Korean skincare. They are known for quality formulas, thoughtful textures, and products that feel modern without being gimmicky. Seeing a trusted Korean brand working with NAD made trying this an easy decision for me. It’s important to be realistic and informed here. There is still limited scientific evidence specifically around topical NAD/NMN use compared with more established skincare ingredients. I think honesty matters. This is not a miracle ingredient that instantly transforms skin. But it is absolutely one of the ingredients to watch as skincare continues evolving. What matters most to me is how a product performs in real life, and this one performs well. The serum feels lightweight, smooth, and easy to use without any heavy fragrance. It absorbs nicely without heaviness or stickiness and layers well with the rest of a routine. That matters because the best serum is the one you’ll actually use consistently. And consistency is the key with products like this. You should not expect dramatic overnight changes. This is more about steady long-term support: helping skin look smoother, fresher, more hydrated, and better maintained over time. I also like that this formula includes astaxanthin, a respected antioxidant often discussed for helping defend against environmental stress and supporting overall skin vitality. Paired with NAD-focused ingredients, it gives the formula a more complete feel rather than relying on one trend ingredient. With regular use, my skin looks healthier, more even, and well cared for. It gives that subtle polished effect I value more than exaggerated promises. Who is this best for? Ingredient-conscious skincare users, people interested in newer longevity-style skincare trends, mature skin, anyone wanting antioxidant support, or those curious about NAD products without paying luxury prices. Who may not love it? If you only want ingredients with decades of established topical data, you may prefer more traditional actives. If you expect dramatic overnight changes, this is not that kind of product. What stands out most is that this makes a newer category feel accessible. Trusted brand, smart formula, fair price, and the kind of steady results that come with consistent use. A very impressive serum from a brand that continues to do things well.

High Concentration PDRN
Scent: PDRN, Size: 1.01 Fl Oz (Pack of 1), Scent: PDRN, Size: 1.01 Fl Oz (Pack of 1)
I absolutely love K-Beauty skincare, and Abib is one of those brands I am genuinely obsessed with. They consistently focus on thoughtful formulations and skin-friendly ingredients, which is exactly what I look for. I’m in my early 30s with combination skin, and since I use a lot of actives (acids, retinol, etc.), I need products that support my skin without feeling heavy or clogging. This PDRN booster cream is such a standout: ✔ PDRN (15,000 ppm) – Helps with skin repair and gives that subtle plumping effect over time. ✔ Peptides – Support firmness and elasticity, especially in areas like smile lines and forehead. ✔ Retinal – A more advanced vitamin A that helps smooth texture and fine lines. ✔ Barrier-supporting ingredients – Keeps skin comfortable and balanced despite active ingredients. The texture surprised me — it’s richer than a serum but still absorbs beautifully without feeling greasy. 💭 My experience: This makes my skin feel instantly smoother and more hydrated, but the real magic is how it improves texture over time. My skin looks more refined and slightly plumper, especially in areas where I tend to lose hydration. ✔ No heaviness ✔ No breakouts ✔ Works well in an active-heavy routine Abib just gets it — effective ingredients, elegant formulas, and results you can actually see.

Gentle but powerful serum!
Scent: Bright Force, Size: 1.01 Fl Oz (Pack of 1)
Soo gentle, moisturizing and it works! So true to its name, its a bright force after first use! This was such a pleasant surprise to me. I did some light research on this product and was confident after reading the ingredient list that it would help my post acne hyperpigmentation and even tone concerns. Im slowly increasing use and only starting in my nighttime routine as instructed. No irritation or break outs. I use almost 2 pumps and it’s enough to easily spread out on my whole face and absorbs nicely without greasiness. It has a very mild scent but it’s barely there. I have sensitive acne prone skin and it worked for me so i would highly recommend to anyone wanting to try the benefits of higher niacinamide concentrations.
