The intex easy set pools are a product line of above-the-ground round swimming pools with inflatable rim and come in sizes from 8 feet diameter up to 18 feet. Some models of 12 feet diameter and up include a ladder to get in and out. These pools are free-standing, which means they are basically a large round sack of flexible PVC plastic with an inflatable ring on top. The easy set pool 'sets' include a filter pump for cycling and cleaning the water, but the pools can also be bought standalone.
This particular model is of 12 feet diameter and holds about 1,800 gallons of water, which means it takes a couple of hours to fill with a garden hose. There are two slightly different 'Easy Set' pools with 12" diameter, the difference is in the wall height. This one is 36" high, which means children will need some sort of ladder or a chair to get in (and need to be supervised as they may not be able to get back out again by themselves!). The smaller brother is 30" high, and holds about 1,500 gallons.
Don't forget to take good care to keep your water clean as it would be wasteful and expensive to re-fill the pool every couple of days- we'll get to more details on this later.
The outside wall height of 36 inches means a tall adult person can sit upright on the ground and the water line will be somewhere around the neck. My four year old daughter can stand it it just fine (head above water!), but she does require a small step or stool to get in and out. Overall there is plenty of space for 2-4 kids splashing around, or for 2 adults to take a dip and stretch out comfortably. Needless to say, this is not for real swimming!
In terms of providing fun for kids and keeping them busy during the summer months, this investment is hard to beat. Plus on really hot days, even the grown ups appreciate a cool dip. In the second season now, the kids are not getting tired of it at all- in contrary. When kid's friends come over, it's always a hit and we keep extra shorts and swimsuits around for that.
