Dry Magnesium Fertilizer for Palms, Citrus, Trees, Shrubs, Roses, Vegetables, Annuals, and Turf
Southern Ag Magnesium Sulfate Fertilizer is a dry, fertilizer-grade magnesium source designed to help correct magnesium deficiency in a wide range of outdoor plants. Magnesium is an essential secondary plant nutrient that supports healthy green color, strong plant growth, and normal chlorophyll production.
Magnesium deficiency commonly appears as yellowing between the veins of older leaves while newer growth may remain green. On palms, symptoms often begin as yellowing along older fronds or leaflets, while the center portion of the palm blade stays green. If left uncorrected, older leaf tips may turn brown and remain damaged.
This easy-to-apply dry fertilizer helps supply water-soluble magnesium directly to the soil. Simply spread the recommended amount over the treatment area and water in thoroughly. No tank mixing or spraying is required.

Excellent chair/great support.
Color: Black Full Mesh, Style: Executive
Excellent, comfortable chair! I was surprised at how easy it was to assemble---but the directions were super clear and all the pieces and parts were labeled. Once I received the chair, I was also surprised with the email follow up from Alice at Molents. All this for a reasonably priced chair.

Great Ergonomic Support and Fit, with Minor Adjustment Caveats
Color: Black Full Mesh, Style: Executive, Color: Black Full Mesh, Style: Executive
As someone who is 5'4" and 140 lbs, the size of the chair feels ideal, and the seat cushion is spacious without feeling overwhelmingly large. The breathable mesh material is high quality, keeping me cool during long working sessions while still feeling sturdy. The back support and adjustable lumbar feature aligns perfectly with my spine and has noticeably reduced my posture fatigue. The height adjustment mechanism operates smoothly to align perfectly with my desk, and the assembly process was surprisingly straightforward, taking less than 20 minutes with clear instructions and tools included. My only slight hesitations are regarding armrests not being long enough. The wheels are not easy to roll on carpet and require a bit of extra effort to move. Maybe a chair mat might be helpful on carpeted floors. However, for the price, the comfort and build are impressive.

High quality and incredible customer service
Color: Black Full Mesh, Style: Executive
This is an extremely well made chair at a very competitive price. The packaging, assembly instructions, as well as the way the hardware was packaged and labeled is probably the best I've seen. I'm particular about tools, and the included allen wrench was better than the normal "included tools" so much so that i actually used it rather than one of my own. The assembly was easy, and the chair itself looks and feels very high quality, and is very comfortable. Perhaps best of all was the level of customer service. I emailed on a weekend to activate the warranty and request the free cushion they offer. I got a personal response in less than a day and they offered upgraded wheels for free as well. This is a company worth doing business with.

Great product AND customer service!
Color: Black Full Mesh, Style: Executive
I'm having a hard time writing this review because I can't tell which one I like better: the product or the customer service!
I work on a computer all day, so a comfortable office chair is critical for me. This chair is great - it's adjustable in every way I need it to be, especially the armrests. The breathable mesh is both durable and supportive, and is more comfortable to sit in than the "overstuffed" chair it replaced.
Let me just say: no company provides better customer service than MOLENTS. Right after assembling my chair (which was very easy, btw), I registered for the 2 year warranty they offer. The NEXT DAY I received an email from Alice in their customer service department 1) to confirm my warranty, 2) to tell me about the free foam seat cover they were sending me, and 3) to make sure the chair was comfortable and easy to assemble. Very few companies take the effort to follow up with customers right after making a purchase like that.
I'm extremely happy with this purchase. This chair is worth MORE than it's weight in gold, and I strongly recommend to anyone thinking about buying an office chair to buy it from MOLENTS - you won't regret it.
Oh, and if Alice's supervisors are reading this: she absolutely deserves a promotion!

Great value and a good chair
Color: Black Full Mesh, Style: Executive
Great chair for the price. Not as solid as an Ergo but it's not thousands of dollars either. It's pretty easy to assemble and the directions are good. It rolls well on LVP flooring and they offer 'upgraded' wheels at no cost from what I can tell. I didn't order them since the included ones work perfectly.
I'm 6'4" and both the seat and arm heights can be adjusted to fit me well. The mesh seat is comfortable and the back works fine. The only downside for me is that the lumbar support doesn't adjust quite high enough to actually reach my lumbar area, but I think it would work for most folks.
Overall it's hard to argue with the cost and even if it only lasts a few years it's worth the money.
