Features
The Joovy Cocoon X2 Double Stroller comes with a pretty standard set of features. It has large side windows, but those are totally clear and not tinted like most of the other trailers in this test. There’s a rear storage compartment with a large mesh pocket for all the extra gear that inevitably accompanies little ones, internal pockets for the passengers to keep themselves organized, two independent lock-off breaks breaks (one for each wheel) a mesh front for summertime breathability and a clear storm proof windshield for cooler or wetter weather. On the very top there is a sun-roof style flap that peels back to reveal a sealed clear window. Lacking is a shade system for when traveling directly into the sun while it is lower on the horizon. The seating system is spartan but has two 5-point harness style seat belts. Because Joovy no longer makes the single Cocoon, we couldn’t include that in this test to be consistent with one passenger trailers. Also, the way the seat belts are sewn in, the Cocoon does not have the option of seating a single passenger in the middle of the trailer. For transport, the frame does collapse and the wheels are removable. All the tires and removable components fit to stow in the collapsed stroller.

The Cocoon is sold as a stroller and the bike arm attachment is sold separately along with an optional parent organizer that straps onto the push handle. Joovy no longer offers a jogger wheel.

Ease of Use
Loading passengers in and out of the Joovy Cocoon X2 Double Stroller is very simple. The twin 5-point harness systems are easy to understand and easy to adjust. Once passengers are loaded, it’s easy to seal up with the zippered mesh cover and the clear vinyl windshield overlaps the zippers and holds in place with a single Velcro strip at the base. When not using the Vinyl windshield, elastic bands on either side keeps the rolled up windshield stowed. Conversion from trailer to stroller is easy to understand but they are a process. The two small stroller wheels need to be popped out using quick-release levers then stowed in the rear cargo compartment of the stroller. The stroller is also easy to collapse for transport or storage with just two clasps and a safety retaining pin. The parking brake system is easy to use although, each of the wheels have their own independent brake. Great for redundancy, but the truth is testers found they ended up getting lazy and only latching one of them anyway.

Durability
The Cocoon X2 is built with a sturdy aluminium frame and is wrapped with durable fabric. All of the components including the zippers, vinyl windows, mesh paneling and moving parts held up well during the testing period. If treated well, namely, keeping it clean and out of the sun, the Cocoon X2 will easily last beyond even a few kids outgrowing it.

Comfort
With such a simple interior, this is where the Cocoon X2 has the biggest opportunity. The back rest of the seat is fairly vertical and offers no ability to recline. This is fine while little riders stay awake, but if they fall asleep they are only held in place by the straps of the harness and heads will flop around some with each start, stop and corner. There’s also no padding along the sides to help buffer or protect in the unfortunate event of an accident. Also, the Cocoon X2 does not have any sort of suspension built into the frame and the ride quality is dependent on how much air is in the 20” tires. When in stroller or jogger mode (if you find a used jogger wheel on eBay), the push handle only has two possible positions (heights) to choose from and while it’s not difficult to switch, it’s not convenient either. 

These trailers were tested for months in various weather conditions in Boulder, Colorado and taken on short road trips and day trips to test their packability and full range of ease-of-use.
