根據香港的《道路交通(安全裝備)規例》(第374F章)，3歲以下的嬰幼兒於乘坐私家車前座時，必須使用具保護性的兒童汽車座椅("兒童座椅")。安全座椅可以在事故發生時緩和外力衝擊，與不使用安全座椅相比，約可減少5.3倍的致死率。

• 0-4歲：可前後向安裝的款式。新生兒報到前通常會物色安全座椅，選擇能從0歲使用到法令規定上限年齡的款式。多數商品可採前後向安裝，方便靈活。

• 4-7歲：前向式為主。前向安裝的成長型安全座椅為主，適用年齡根據商品不同，有0-7歲、0-12歲、2-12歲等多樣化選擇。主要根據小孩身高選擇，不勒到脖子為主，選擇可多段調節頭靠高度、椅背角度的款式。

選購時將ADAC撞擊測試成績納入考量，選擇分數在3.5分以下的款式 。ADAC為全德汽車俱樂部的英文縮寫，是一間非營利的民間機構，以客觀角度進行各項汽車安全性檢驗。計分主要劃分為五個等級：0.6～1.5分（非常好），1.6～2.5分（好），2.6～3.5分（滿意），3.6～4.5分（勉強及格），4.6分以上（有缺陷不推薦）。

安全帶固定適用於沒有ISOFIX配件的舊車款，安裝較費力且易出現安裝失誤。ISOFIX安裝簡單快速，穩定度更好，避免安裝錯誤。2016年起的國產轎車應配備ISOFIX，建議優先選擇支援ISOFIX安裝的安全座椅。

• 360度旋轉: 部分商品底座能360度旋轉，方便上下車，減輕家長腰手負擔。選擇低底座設計，騰出更多車內空間，方便抱起熟睡中的嬰兒或幼兒。

• 透氣、減震材質: 選擇椅座、配件使用透氣、減震材質的款式，改善悶熱、震動的不適感。

• 椅墊、頭靠可拆卸: 選擇椅墊、頭靠可拆卸機洗的款式，方便維護整潔。

According to Hong Kong's Road Traffic (Safety Equipment) Regulations (Chapter 374F), infants and young children under the age of 3 must use protective child car seats when riding in the front seat of a private car. Safety seats can mitigate external force impacts in the event of an accident, reducing the fatality rate by approximately 5.3 times compared to not using a safety seat.

• 0-4 years: Styles that can be installed facing both forward and backward. Typically, parents look for safety seats before the newborn arrives, choosing styles that can be used from birth to the legal upper age limit of 0-4 years. Most products can be installed facing both forward and backward, offering flexibility.

• 4-7 years: Forward-facing seats are predominant. Growth-oriented safety seats for forward-facing installation are common, with age suitability ranging from 0-7 years, 0-12 years, 2-12 years, and various other options. Selection is primarily based on the child's height, ensuring no neck strain, and choosing styles that allow for multi-level adjustments of headrest height and seat back angle.

Consider ADAC crash test results when making a purchase, selecting styles with scores below 3.5 points. ADAC stands for the Allgemeiner Deutscher Automobil-Club, a non-profit organization that conducts comprehensive car safety inspections from an objective standpoint. Scoring is primarily divided into five categories: 0.6-1.5 points (very good), 1.6-2.5 points (good), 2.6-3.5 points (satisfactory), 3.6-4.5 points (barely passing), and above 4.6 points (defective and not recommended).

Seatbelt fixing is suitable for older car models without ISOFIX attachments, which can be more laborious to install and prone to installation errors. ISOFIX installation is quick and easy, providing better stability and reducing the risk of incorrect installation. Since 2016, domestic sedans should be equipped with ISOFIX, making it advisable to prioritize safety seats that support ISOFIX installation.

• 360-degree rotation: Some products have a base that can rotate 360 degrees, making it easier for parents to get in and out of the car, reducing strain on the back and hands. Choose designs with a low base to free up more interior space, making it easier to lift a sleeping infant or toddler.

• Breathable, shock-absorbing materials: Opt for styles that use breathable, shock-absorbing materials for the seat and accessories to improve comfort by reducing heat and vibrations.

• Removable seat cushions and headrest: Select styles with removable seat cushions and headrests that are machine washable for easy maintenance.
