Sulfate of Potash 0-0-50 Granular Fertilizer
Southern AG Sulfate of Potash 0-0-50 Granular Fertilizer is a concentrated potassium fertilizer designed to help correct potassium deficiencies in low-potassium soils. With a 0-0-50 fertilizer analysis, it delivers soluble potash without adding nitrogen or phosphate, making it a targeted solution when plants need potassium support for stronger roots, sturdier stems, healthier tubers, and improved overall plant vigor. The product contains granular potassium sulfate and is intended for soil application, not spray use.
This granular potash fertilizer is suitable for vegetables, flowers, shrubs, and lawns. It may also be used to help address potassium deficiency in plants such as avocado, beans, corn, cherries, citrus, grapes, palms, and roses. Potassium plays an important role in root growth, water regulation, photosynthesis, plant strength, winter hardiness, and disease resistance.

Quiet Inflation and Solid Comfort
Style: 22", Color: Grey, Size: Queen
I’ve been really impressed with this air mattress. The firmness is spot on—it doesn’t feel like you’re sinking or fighting to stay level like a lot of other inflatables. It actually holds its shape well enough to feel close to a real bed, which surprised me.
One of the biggest things for me was how well it holds air. I left it set up for 3 days straight, and it barely lost any pressure. I only needed to top it off slightly, which is way better than most air mattresses I’ve used that need daily reinflation.
The built-in pump is another win. It inflates quickly and, more importantly, it’s relatively quiet compared to others. You’re not blasting the whole house when you set it up late at night. Deflation is just as easy, which makes packing it up for storage or camping super convenient.
I’ve used it both for guests and for camping, and it performs great in both situations. It’s comfortable enough that guests don’t feel like they’re getting the “temporary bed,” and durable enough to handle being moved around.
Overall, this is one of the better air mattresses I’ve owned—reliable, comfortable, and easy to use. Definitely recommend if you want something that won’t let you down after the first night.

From an IDOO 18" to this Intex 22" queen air mattress
Style: 22", Color: Grey, Size: Queen
I have been sleeping on air mattresses for about 5 years now. Yes, every night. The reason is that I cannot afford a decent new mattress and before switching to an air mattress, I had used mattresses. Most developed "sink holes" and those who sleep on an older mattress know what I mean - a spring or something inside has shifted and that spot...well, it's a dip that you have to figure out how to avoid when sleeping. But the basic reason is because I am an older lady that lives alone and when I have moved, I have moved myself so as not to bother people. I have mostly flat pack furniture so I can break it down and move it myself. Having an air mattress fits right in with that ease of moving my own stuff. The IDOO I had was a great deal, though I had last had a King Coil 22" that I really liked EXCEPT for their "pillow" area (the part at the head is inclined and that bothered me since I am an "arm sleeper" - put one arm up under my pillow, under my head and hang it off the bed). Other than that part King Coil is a great air mattress bed. Now for this Intex - I have had a couple of different Intex items and find they make quality stuff - first was a smaller, rectangular pool that wasn't too hard to set up (but I did need a friend to help with putting it up) and I currently have their inflatable loveseat that unfolds to become a bed. It's a nice extra piece of furniture/bed, but wish it had the internal pump which it doesn't. Still, it is a serviceable spare seating and sleeping piece that can be put up quickly enough. NOW, for this bed - back to my 22" height and I am SO HAPPY with that part of it. When you are older, getting UP off something is harder than scooting down off that same thing! Meaning that I have no problem getting on a bed (no matter what the height), but in the morning, when I'm groggy and not 100%, trying to push myself up off the 18" wasn't horrible, but it wasn't fun at all. With this Intex 22" queen, my feet dangle just a bit off the floor and pushing myself off and DOWN is just so much easier. I was also relieved that the pump is at the top (or could be the bottom, depending on how you orient the bed) as my outlet is at that spot on the wall behind the bed. The IDOO had the pump on the side so the cord had to be put up under the bed...I didn't like that. This Intex, like all the air mattresses with an internal pump, it inflates (and deflates) very quickly. Around 5 minutes. What's easy is taking down an air mattress - most of them come with a carry case as this one did - and if you flip the sides in, then do a fourths fold up, it will fit in the bag and isn't too terribly heavy even for me to carry. The IDOO developed a leak and instead of trying to patch it, as I have slept on it for about 2 years, I deflated it, put it in the bag it came with and threw it away. This Intex, I had it out of the box an fully inflated in less than 10 minutes. Made the bed and laid down on it - aaahhhh! So, if you are in need of a spare bed for overnight guests on occasion OR you have had it with your lumpy old "regular" mattress and having sticker shock over the memory foam, purple, pillow top and other replacements, you might want to try an air mattress. Even if you only use it long enough to save enough money for one of those $500-$1000 mattress, this $75 mattress will allow you to sleep well, night after night after night.

Better than our actual mattress!!
Style: 22", Color: Grey, Size: Queen, Style: 22", Color: Grey, Size: Queen
Purchased for company to stay with us in our apartment. I honestly had no idea they made air mattresses this tall until I saw a friend with one!
My husband and I tested it out last night. We were both really impressed!
1. Really easy to inflate! First time having an internal air pump. No more forgetting the pump! The motor wasn’t nearly as loud as our previous air pump! I was able to talk to my husband and he could still hear me over the pump running.
2. Really comfortable and supportive! We chose not to inflate it fully so it contoured to our bodies better. We slept on the mattress with no sheets and I wasn’t able to feel the creases in the top which was nice. No issues with sagging and we both didn’t wake up smooshed in the middle. My husband got up in the middle of the night and I didn’t notice. So movement of the mattress is minimal! Easy to get on and off with the 22” height.
3. Easy to deflate! We followed the instructions for folding and we got it in the storage bag with no issues. Just make sure all of the air is out before you fold it.
4. High quality! We had both of our small dogs on this with us. I was afraid of their nails poking a hole but so far so good! Only a little bit of air leaked out but it could’ve been the material stretching out during the night.
Cons: The pump does not shut off automatically when inflating or deflating. So keep an eye on it so it doesn’t overfill. The mattress does get cold at night. My husband and I both mentioned that in the morning. I had to roll up in my blanket to stay warm. I’ll try sheets on next time. In the summer it might not be that big of an issue. Ours came with one patch. Hopefully we won’t need to use it.

Love this bed
Style: 22", Color: Grey, Size: Queen
This bed is more than what I can ask for with the built in air pump. It's firm but comfortable my guest never complained I loved the height of the one I purchased and I loved that it gives you other height options. Super easy to set up and it holds air well. Other blow up beds I've purchased over time deflated and this one is still going strong after almost two months without me having to release the air and replace it. Had a bit of an oder when I first opened it but it's gone now. So happy with my purchase.

Like it
Color: Hot Pink/Smoke
The Speedo Kids’ Sunny G swimming goggles were very much liked by the child. They sit comfortably, do not leak and do not put pressure on the eyes. The soft strap does not pull the hair and is easily adjustable, so the child can put them on himself. They hold well during swimming and do not slip. The lenses do not fog up and provide good visibility underwater.
