The GoTime No Back is a backless booster for children at least 5 years old who weigh 40 to 120 lb and are 44 to 60 in tall, with ear tops below the top of the vehicle headrest. It works only with a vehicle lap and shoulder belt, weighs 3 lb and is not certified for aircraft.
It suits an older child who needs a boost to fit the vehicle belt, and a family that moves a booster between cars. The trade-off is that the seat gives no head support, so the vehicle headrest must reach above the child's ears. The GoTime LX shares the same manual and limits but adds a backrest with 7 height positions, and Evenflo lists it at 7.1 lb.

This seat covers one stage. Check the date label on the shell before using a hand-me-down; every seat has an expiry.
| Mode | Child weight | Child height | Minimum age | Conditions |
|---|---|---|---|---|
| Backless booster | 40 to 120 lb | 44 to 60 in | 5 years | At least 5 years old; ears below top of vehicle headrest. |
A child must meet every limit for the mode they use. The labels on your seat and its manual are the final word.

At 7.44 in at its widest, this seat is one of the narrower ones in its class and is a candidate for three across in many mid-size cars. It weighs 3 lb, which matters if you will move it between cars or carry it through an airport.

When they differ, follow the manual and the labels on your seat.
The vehicle lap and shoulder belt hold the child; the booster raises them so the belt fits. Both parts of the belt go under the armrests on the booster. The lap belt sits low and snug across the hips, just touching the thighs, and the shoulder belt crosses midway between neck and shoulder. The child's back sits flat against the vehicle seat. Never use a lap belt alone, door-mounted belts, belts that move along the frame when the door opens, or lap and shoulder belts with two retractors. Use it only on forward-facing vehicle seats with backs that lock.

The clip is only for when the shoulder belt does not lie midway between the neck and shoulder on its own. Thread the looped end of its strap through the anchor point on the back of the base, pass the clip through the loop and pull it tight. Place the booster, attach the clip to the vehicle shoulder belt and pull the adjustment strap until the clip is at or slightly above the child's shoulder. If the belt still crosses the neck or falls off the shoulder, the manual says to try another seat or not use the booster.

The manual describes no lower anchor connectors. It says to keep the booster buckled in with the vehicle belt when nobody is sitting in it, because a loose booster can strike someone in a crash. To clean, unhook the pad's elastic loops and pull down the retainer clips at the front, then machine wash it separately in cold water on a delicate cycle and tumble dry 10 to 15 minutes on low heat. Plastic parts wipe clean with mild soap. The instructions store in slots under the seat, and the seat expires on the date shown on its label.

Each campaign naming this family was read against this model’s numbers and build dates, and none covers it. Still check your seat’s model number and date of manufacture before use, especially on a used seat.
The manual requires a child at least five years old, 40 to 120 lb and 44 to 60 in tall. The tops of the ears must be below the top of the vehicle headrest.

No. The manual says it is not certified for aircraft use, because a belt-positioning booster needs a lap and shoulder belt.

The manual describes no lower anchor connectors. It says to keep the booster buckled with the vehicle seat belt whenever it is empty.

When the child exceeds 120 lb or 60 in, or the ear tops pass the top of the vehicle headrest. The manual says the child may then be ready for the vehicle belt alone.

The GoTime LX has the same 40 to 120 lb range but adds a backrest with 7 height positions, and Evenflo lists it at 7.1 lb. The No Back is the lighter choice at 3 lb.
