Overview
The Britax E1D231Q is a car seat rated for children up to 65 pounds and built to install rear facing or forward facing using the vehicle's seat belt. The shell is polyester and the whole seat weighs about 28 pounds.
A 65 pound weight limit combined with both rear and forward facing modes points to a convertible style seat meant to carry a child from the toddler years up toward booster age, rather than an infant only carrier. Britax lists seat belt installation only here, with no LATCH mention, so it is worth checking your vehicle's seat belt routing before buying. It holds a 4.5 rating across 116 reviews and around 200 units bought in the past month.

Who it's for
Parents who want one seat to cover both rear and forward facing stages rather than buying two separate seats will find this fits their plan. Anyone who specifically needs LATCH installation should look elsewhere, since only seat belt installation is listed here.
Strengths and trade-offs
Drawn from this product's published specifications.
- 65 pound weight capacity covers rear and forward facing stages
- Converts between rear and forward facing without buying a second seat
- Seat belt installation only, no LATCH listed
- At 28 pounds it is heavier than infant only carriers to move between cars
Performance notes
At 65 pounds, the weight capacity should carry most children well past the toddler stage before they need a booster, and the dual rear and forward facing modes mean the seat does not need replacing when a child turns to face forward. Installation is by seat belt, so fit will depend on how your vehicle's belt routes through the seat's belt path.
