At first, I had my doubts that an inflatable structure could function well as a spa. However, the Coleman Lay-Z Spa exceeded my expectations in almost every way. It truly doesn’t take any tools and is ready to fill in minutes! Unlike a traditional spa, this one can be stored away during winter and moved easily if you change residence. Pros • The instructions come in written and video form, and for the most part are useful. (It took me a minute to realize that the buttons are toggles and to deactivate you must press again, this little bit of information was buried in the section on the pump instead of noted in the set up. And it also doesn't mention the ground liner in the written instructions.) • It includes a chemical floater, which is a nice inclusion, but I would have been really happy if it came with a starter chlorine tablet. • The pump functions as the inflator (in this capacity, it is quite noisy, unlike when it is attached to the spa). • The pump also has a built in GFCI, which is a nice feature. • There’s a pressure gauge included to make sure it’s inflated to the proper pressure. • I like the inflatable part of the cover because it floats on the water and is very neat in appearance as well as acts like an insulator while heating. • The inflated spa is a simple cylindrical shape inside and out, and the interior diameter is approximately 60 inches. I have to say that even empty of water, the sides of the spa are very rigid and even my husband could sit on them. There’s no sagging or collapsing. • There are two filters that go on the inside of the spa. They are about the size of a small cantaloupe, and house a filter that you can clean by hosing them off or replacing. • Attaching the pump to the spa, I needed the help of my husband as I wasn’t able to get the fittings tight by hand. But the fittings haven’t leaked or anything. • While heating and filtering, the pump is so quiet!! • While making the Lay-Z Massage bubbles, the noise from the pump is very reasonable – the noise of the water is louder. • There is a soft ring, made from the same material as the spa, around the inside of the spa at the bottom which is where the air is pumped to create the Lay-Z Massage bubbles. I was pleasantly surprised at the amount of turbulence it created – there was much more than I anticipated. (Watch the video to see the bubbles in action.) Cons • Keep in mind, when choosing a location for your spa, that it will need a flat surface that can support the weight and an electrical outlet. • During the unboxing, I did need the help of my husband because the deflated spa was heavy for me. • The pump is quite loud while pumping air to inflate. (But don’t worry, when pumping the water or bubbles it isn’t loud at all.) • Because I received my spa in the fall, the weather was chilly. So the concrete was cold and the water from the hose was cold. With these conditions, the heater took several hours to raise the water temperature a few degrees. I let the heater run over night and when I woke up it was at 104. So unfortunately, I don’t have a good idea of how long the heating takes during warmer weather. But once it’s heated, it maintains the temperature well.
