HKM-3874515 3-in-1 Lightweight Baby Stroller with Car Seat Reversible Seat UPF 50 Plus Canopy Cup Holder for Newborn to 3 Years
HKM-3874515
Three Ways to Ride One Light Frame
The HKM-3874515 covers the whole first three years on one light chassis. A flat carrycot takes a newborn through the first months, a detachable car seat clicks on for the ride home from hospital, and the reversible seat unit carries a child to about three. The frame is drawn from 6061 aluminum and comes in around 16.5 lb to lift into a boot, with independent coil springs at all four wheels and a one-hand fold that closes the chassis into a compact package. The canopy is rated UPF 50+ and a cup holder sits on the handlebar.
Key Features
Nine details that make the HKM-3874515 a complete travel system.
Three Modes in One
A carrycot for a newborn, a detachable car seat for the ride home, and a seat unit that carries a child to about three years all run on the same light chassis.
6061 Aluminum Frame
The chassis is drawn from 6061 aluminum so it weighs around 16.5 lb, yet it still takes a 50 lb child without flexing on a tight corner or over a kerb edge.
Detachable Car Seat
The car seat carrier lifts off with its own handle and clicks back onto the same frame, so a sleeping baby moves from car to pavement without being woken.
Flat Carrycot Base
A deep carrycot with a lie-flat base gives a newborn the level surface the first months call for, and it lifts off the frame on its own whenever you stop.
Reversible Seat Unit
The seat turns between parent-facing and forward-facing without being unclipped, so a child faces you on a quiet walk and faces the street on a busy one.
One-Hand Folding
One motion collapses the frame inward and catches it shut, so the stroller folds into a compact package while you hold a baby on the other arm with you.
Four-Wheel Suspension
Independent coil springs sit at each of the wheels, so a cobbled lane or a broken pavement sends only a small share of that vibration up to a sleeping baby.
UPF 50+ Canopy Shade
The three-panel canopy carries a UPF 50+ rating and blocks the large majority of UVA and UVB, so a mid-afternoon walk keeps a child out of direct sun all day.
Five-Point Safety Harness
A padded five-point restraint holds a child at the chest and the hips with webbing that runs flat, so it cannot twist against a small shoulder on a bumpy stretch.
Overview
One frame, three ways to carry a child.
The HKM-3874515 is a 3-in-1 travel system on a 6061 aluminum frame. A flat carrycot takes a newborn through the first months, a detachable car seat clicks onto the chassis for the ride home, and a reversible seat unit carries a child to about 50 lb or three years. The seat turns between parent-facing and forward-facing without being unclipped. Independent coil springs run at all four wheels, so a cobbled lane or a broken pavement reaches a sleeping child as little more than a mild sway. One motion folds the frame into a compact package light enough to lift into a boot, and the chassis comes in around 16.5 lb. A UPF 50+ three-panel canopy covers the seat, a five-point harness holds a child square, and a cup holder sits on the handlebar.
Carrycot, Car Seat, Seat
Three ways to carry a child on one frame.
A flat carrycot takes a newborn through the first months, a detachable car seat clicks onto the chassis, and a reversible seat unit carries a child to about three years. The seat turns without being unclipped.

Fold & Suspension
How it folds, and how it rides over rough ground.
Two things decide how a travel system lives with a family, and this one is built around both. The fold is a single motion: release it and the frame collapses inward and catches shut, so the chassis folds into a compact package while you hold a baby on the other arm. The ride runs on independent coil springs at all four wheels, so a cobbled lane or a broken pavement sends a far smaller share of the vibration up to a sleeping child than a rigid frame would. Small front castors turn the stroller in a narrow aisle, and the larger rear wheels carry the load over a kerb.
Daily Use & Care
A short routine keeps the HKM-3874515 ready to go.
Wipe the 6061 aluminum frame with a soft, dry cloth so the finish stays clean through wet pavements and winter grit.
Spot clean the seat textiles with mild soap and water, then let them air dry fully away from a radiator.
Wipe the carrycot and the car seat shell, and check that the carrier still clips onto the frame without play.
Inspect the five-point harness webbing and buckle for wear and fraying before a child is placed in the seat.
Test the brake by stepping the pedal until both rear wheels lock, then release it fully and check it again.
Clear grit and hair from the front castors and their housings so that the steering stays light and true.
Empty the under-seat basket after a shopping trip and wipe the base before anything is stored there again.
Store the stroller indoors and out of prolonged direct sun so the canopy and the seat fabric keep their original shade.

Why Choose the HKM-3874515
Nine reasons families pick the HKM-3874515.
Three Modes in One
A carrycot, a detachable car seat and a reversible seat unit all run on one frame, so a family buys a single stroller for the whole of the first three years.
Light Alloy Build
A 6061 aluminum frame comes in around 16.5 lb for the chassis, so it lifts into a car boot and up a kerb without the struggle of a heavier steel-framed model.
Reversible Seating
The seat faces the parent or faces forward without being unclipped from the frame, so a child can watch you on a quiet walk and watch the street on a busy one.
Car Seat That Lifts Off
The carrier comes off with its own handle and clicks back onto the same frame, so a sleeping baby moves from the car to the pavement without being woken.
One-Hand Folding
A single motion collapses the frame and catches it shut, so the stroller folds into a compact package while you hold a baby on your other arm with you.
Smooth Suspension
Independent coil springs at all four wheels soak up a cobbled lane or a broken pavement, so a sleeping child feels only a mild sway instead of a hard jolt.
Harness Security
A padded five-point restraint spreads the load across the chest and the hips, so a child stays square in the seat even over a rough stretch of paving or trail.
Sun Shielded Ride
A three-panel canopy rated UPF 50+ blocks the large majority of UVA and UVB, so a mid-afternoon walk keeps a child out of the direct sun for the whole day.
Storage and Cup Holder
A full-width basket under the seat takes a shopping bag, and a cup holder on the handlebar keeps a bottle within easy reach on a long afternoon walk out.
Controls & Indicators
What each control on the HKM-3874515 does.
Fold Trigger
The release collapses the frame in one motion and then trips the latch that holds the whole frame shut again.
Seat Release
The release under the seat lets the unit turn from parent facing to forward facing without being unclipped.
Recline Lever
The lever at the back of the seat sets the backrest from upright through to the sleep position in steps.
Harness Buckle
The central buckle joins the five padded straps and releases with a single press of the button on the unit.
Cup Holder
The holder on the bar keeps a bottle upright and within reach while you push the stroller with both hands.
Parking Brake
The pedal beside the rear wheels locks both of them at once and releases with a lift of the toe afterwards.
Frequently Asked Questions
Quick answers about the HKM-3874515.
What ages does the stroller cover?
A flat carrycot covers the newborn months, the car seat covers the ride home, and the seat unit carries a child to about 36 months and a 50 lb load.
Does it really come with a car seat?
Yes. A detachable carrier with its own handle is part of the set and clicks onto the same chassis as the seat unit and the carrycot.
How does the seat turn around?
Lift the release under the seat and turn the unit; it stays on the frame, so there is no second part to store.
What is the fold like?
One motion of the release collapses the frame inward and catches it shut, so it folds into a compact package for a car boot.
What kind of suspension is it?
Independent coil springs sit at all four wheels, which is what keeps a cobbled lane or a broken pavement from reaching a sleeping child.
What safety standards does it meet?
The stroller is built to ASTM F833 and EN 1888, covering the frame, the brakes and the five-point restraint.
Quick Troubleshooting
Common HKM-3874515 issues and what to check first.
The stroller will not fold
Check that the release is fully pressed, then push the frame down until the latch clicks into its place.
The seat will not turn
Lift the release under the seat fully and clear any fabric caught in the housing before turning the unit.
The car seat will not click on
Check that no fabric or strap is trapped under the mount, then press the carrier down until both sides catch.
The ride feels hard
Clear grit from the spring housings and the castors, and check that nothing is jammed between a spring and its seat.
The brake will not lock
Step the pedal down fully and confirm both rear wheels are held before you leave the stroller standing still.
The castors drag when turning
Clear hair and grit from the castor housings so the wheels swivel freely through their full turn once again.
