The Radian is an option -- 49" is a guestimate total height ... since some kids are leggy while others have long torsos this is just a guideline: what's important is that the top harness slots are at about 18" up (Britax = about 17" / Recaro Signo = about 19" / Safeguard Go = about 17").

I have been able to puzzle 2 RF Britax seats + 1 FF Britax or 1 RF + 2 FF in the Taurus. The Radian is the narrowest of those options listed above & Sunshine Kids allows using the Radian80 with child's shoulders up to 1.5" above the top harness slot. No one else does.

Worse comes to worse, assuming there is enough head support (at least eye level, preferably with room to grow), the Ride Safer Travel Vest in the center might be a good choice -- less enjoyable to buckle, but it's very safe in the center with lap belt + top tether anchor (I dont have my LATCH manual to know if you have a top tether anchor point for the center?)

However, a 5.5 year old should be able to learn to use a booster correctly -- if you don't have side curtain airbags I suggest the Britax Parkway or Monarch, Compass B510, Recaro Young Style because these meet U.S. standards as well as side impact crash testing. Showing kiddo the GM booster video (within my website) can help teach him to use a booster correctly. You can also engage the shoulder belt retractable locking mechanism as an added reminder to sit still.

	Forward Facing Car Seats A forward-facing car seat is one in which the child sits facing the front of the car. The seat should be installed in the back seat of your vehicle. Most forward-facing only seats are for children above 20 pounds.

	Britax - Click for more info Britax International has been producing reliable child safety products for over 30 years. Not only does Britax have decades of experience creating car seats and other children's safety equipment, Britax has a long standing reputation as an industry leader and innovator. Britax International is headquartered in the United Kingdom, but Britax car seats are designed and manufactured at facilities in Germany, Austria, and the United States. In the summer of 2002, Britax strengthened their commitment to creating the safest car seats with the opening of a brand new, state-of-the-art crash testing facility in North Carolina. Britax car seats have a reputation around the world for being some of the safest, most reliable, and best designed child safety seats ever made.

	Rear Facing Car Seats A rear-facing seat is one in which the infant faces the back of the car. Always install a rear-facing seat in the back seat of your car. This is the safest position for an infant. NEVER place a rear-facing seat in the front seat of a vehicle with passenger airbags.

	Booster Seat A booster seat raises your child up so that the car's lap and shoulder belts fit correctly. The lap belt should fall across the upper thighs. The shoulder belt should go across the middle of the shoulder and chest. A booster seat is used for older children up to about 80 pounds. Some states have passed laws requiring booster seats for children up to age 8 or 80 pounds. Check your state's law.

	Britax Parkway - Click for more info The new Parkway Booster from Britax builds on their company's reputation as the maker of some of the safest seats on the market today. It's one of the only boosters to offer True Side Impact Protection - the EPS foam-padded headrest and side "wings" aren't just great for naps, they're engineered to provide vital protection to your child in the event of a side-impact crash. (Side-impact crashes are the leading cause of death for children ages 6-14, making this an issue of major importance for booster seats.)

	Britax Monarch - Click for more info The Britax Monarch is another fine addition to the Britax family of car seats and boosters. UK based Britax is widely renowned for creating some of the highest quality convertible, infant, and booster car seats in the world – and the German designed Monarch is one of the latest and greatest additions. Both the Monarch and the Britax Parkway offer True Side Impact Protection, utilizing thick EPS foam lined side wings around the head and torso area. These provide not only side impact protection, but also the deep headrest makes a comfortable spot for your child to rest their head once they nod off. The deep side wings cocoon the passenger in an impact reducing shell. The back of the Monarch is removable and the belt threading positions are color-coded to reduce the potential for improper use.

	the First Years formerly Compass - Click for more info Compass was founded by a group of fathers who had spent years in the corporate world developing child care products. Disillusioned with the slew of problems that come with working for a giant conglomerate, this group set out the make their own mark on the child care industry in 2003. Compass' first innovative booster seat, the B500, started shipping in January of 2004. This was the first foldable belt-positioning booster on the market, and its design was so praised by the industry that Compass received a Juvenile Products Manufacturing Association (JPMA) Innovation Award 5 months after its release. The great minds at Compass have now taken the next step with their success by releasing some fantastic infant car seats and compatible strollers, all of which are designed with the same innovative simplicity that make Compass Boosters such a sought after product. No longer just "The Booster People", Compass is making a serious run at the competition by offering the I-410 and I-420 Infant Car Seats , as well as the Magnesium S330 Stroller and Magnesium T730 Travel System.

	Sunshine Kids - Click for more info Makers of a number of accessories geared towards making parents lives easier, Sunshine Kids has recently embarked in a new direction. In 2005 they unveiled their first car seat, the Radian. Their years of experience working in children's products focusued on child comfort and parent convenience shine through in this unique convertible car seat. The Radian is packed with safety features and is the first ever folding convertible car seat appealing to parents who car pool or travel often.

	Sunshine Kids Radian 80 or 65 - Click for more info If "the Sunshine Kid's Radian 80 convertible car seat is (probably) the only car seat you will ever need," the "probably" part of this statement comes into play when you directly compare the Radian 80 with the Britax Regent. While the Radian 80 has a very high weight capacity, the seat width is only 10" vs. the Regent's 14" seat. The Britax Regent may be a bit wider, but it is very bulky, is only forward facing, and does not fold like the Radian 80. Because the Radian 80 is so narrow, you can potentially put three of them side by side in the back seat. Three Regents side by side? Impossible.

	RECARO Signo - Click for more info The RECARO Signo car seat is the premier convertible child seat RECARO produces. With its 5-70 lbs weight capacity, adjustable harness, and forward or rear-facing convertibility, the deluxe RECARO Signo may be the only car seat you will ever need. The Signo offers the same basic features and specifications as the RECARO Como convertible, but adds a few features - such as double wall head support and infinite harness adjustment settings.

	LATCH LATCH stands for Lower Anchors and Tethers for CHildren. It is a system mandated by the Federal government in an effort to standardize and simplify the installation of child restraints without using the vehicle's seat belt system. New vehicles and child safety seats manufactured on and after September 1, 2002 will be equipped with the LATCH system. Cars, minivans, and light trucks will be required to have anchor points between the vehicle's seat cushion and the seat back in at least two rear seating positions, and a top tether anchor (with the exception of convertibles). Child safety seats will have a lower set of attachments that fasten to the vehicle anchors. Most forward-facing child safety seats will also have a top strap (tether) that attaches to the top anchor in the vehicle.

	Top-Tether A top tether (or top strap) is the supplemental attachment now standard on almost every new carseat in the USA. Top tethers can be used with either the seat belt or with the lower anchors (as part of the LATCH system). In other countries, their use may be required by law. A top-tether is simply a strap that connects the top of the carseat to an anchor mounted in the vehicle at a location behind the carseat, usually the parcel shelf or a point on the floor of the cargo area. It is designed to prevent the forward movement of the top of a forward-facing carseat in a frontal crash. This reduces the head excursion of the child, and can reduce the chances of injury. Almost all current carseats can only meet the tougher new federal safety standards when the tether is used, even though they must still meet the minimum safety standards without a tether.

	SafeGuard - Click for more info Indiana Mills and Manufacturing (IMMI) is SafeGuard’s parent company, and has been in the business of developing and manufacturing quality safety systems for every facet of the transportation industry for over 40 years, covering everything from the heavy truck and agricultural industries to child seating.

Based in Westfield, Indiana, SafeGuard has been creating and testing essential components used across the child safety seat industry through their state of the art crash testing facilities since 1961. The SafeGuard and SafeGuard Go are IMMI’s first direct foray into the child safety seat market, and the results are simply outstanding. No other car seats or boosters are designed with as much attention to structural integrity, ease of installation, and total child safety. This seat has been subjected to the most thorough and extensive testing “ever conducted in the industry”: virtual prototyping with computer models; rigorous front, side, and rear impact crash testing; and environmental testing in a range of climates and road types.
