Diono Connect3 R Backless Booster Pack of 2 - Slim Fit Booster

In this review of the Diono Connect3 R backless booster pack of 2, the bottom line is simple: parents who need a slim, travel-friendly booster that fits many mid-sized sedans and SUVs will find strong value here. The product is aimed at families with children from 40-120 lbs who need a lightweight, easy-to-install booster for everyday driving or trips. The single biggest reason to buy is the Connect3's slim-fit design that claims to fit 3-across while still offering comfort features like 2TexFoam and a molded seat contour for easier belt access.

Key Features

• Slim-fit design: At under 17 in wide, the booster is engineered to fit three seats across in many mid-sized vehicles while preserving interior seat space.
• EasyReach buckle access: The seat contour around the EasyPath lap belt guides provides more accessible buckle reach for both parents and children during install and use.
• Built-in carry handle: The molded carry handle makes the boosters easier to move between vehicles or carry when traveling with minimal extra effort.
• Comfortable seating: The premium 2TexFoam seat base offers cushioning for longer rides while maintaining a compact profile.
• Removable cup holders: Two cup holders nest between seats for a true 3-across configuration and stow under the booster when not needed, reducing clutter.
• Extended use: Rated for children 40-120 lbs, the boosters cover several years of growth for typical children in that weight range.

Who It's For

The Connect3 R pack is best for families who regularly transport two or three children in the back seat and need a narrow, lightweight booster that travels well between vehicles. It also suits caregivers who value a simple install process and easier buckle access, since many customers report the unit is straightforward to set up.

Those who should look elsewhere include families with unusually wide vehicle seats or those who must guarantee a three-across fit in every vehicle; customer feedback is mixed on whether genuine 3-across installation is possible in all standard family vehicles. Also consider a high-back booster if you want integrated head and neck support rather than a backless model.

Pros & Cons

Pros

• Very slim footprint allows tighter packing of back seats for many mid-sized sedans and SUVs.
• Easy installation is consistently noted by customers, reducing hassle for busy families.
• Two removable cup holders provide flexibility and neat storage under the seat when not in use.
• Lightweight with a built-in handle for convenient travel between vehicles.

Cons

• Fit is mixed for true 3-across setups; some vehicles may not accommodate three boosters side-by-side.
• As a backless booster, it lacks integrated head support that some parents prefer for younger or sleeping children.

Our Verdict

The Diono Connect3 R backless booster pack of 2 is a practical, travel-friendly option for families needing a slim, lightweight booster that often fits three across in mid-sized cars and SUVs.
