This sits in  12” of water on the Cabo shelf the back sinks and the front hovers about 6 inch's but it does not move and looks perfect , Remember the other regular pool chairs you see are 
hollow and float so you have to fill with water to sink them in place , The problem is now they 
weigh 100 Lbs. and take two strong people to remove if the toddlers come over and use the shallow shelf to play . With these chairs  i can easily lift in and out so that was the reason I got these they are not lightweight plastic they are solid resin and are very good quality they weigh about  33 lbs so it’s easy to take out of pool so kids can play in the shallow. , also I got the Ayvan / Maxamillion outdoor side 
table matches perfect sku : W005759156 that I cut legs down 2” shorter and used liquid soap to help pound onto tabletop as they are super super !!!!  tight so use a rubber mallet . The combo is perfect match . Super happy !!!
