IN SHORT
For wardrobe drawers, specify the runner type, how the drawer box is built and what the base is made of, then test every drawer fully loaded at handover. A drawer that glides when empty can still sag, rub or jam once it carries a week of folded clothes in humid air.
Drawers do the hardest work in a wardrobe: they open and close every day, carry folded clothes that weigh more than they look, and sit in humid air that tests every joint. Yet many quotations say only drawers, with nothing about runners or construction. This guide explains the runner types in plain words, how a drawer box and its base should be built, what loads to plan for, and what to test before you accept the work.
Runners are the metal slides that let a drawer travel in and out, and they come in three everyday types. Side-mounted ball-bearing runners are a pair of rails fixed to the sides of the drawer and the cabinet; you can see them beside the drawer, they feel solid and they suit heavier contents. Roller runners use small wheels on a track; they are simple and light, but they feel rougher and suit light, occasional use. Undermount runners sit beneath the drawer box and are hidden from view, which gives a clean look and a smooth glide, and they often come with soft-close. Beyond the type, ask two questions. Does the drawer pull out fully so you can reach the back, or only part of the way? And does it close softly or bang? In a humid climate also ask about the runner's finish, because bare metal marks more easily than coated metal. Which brand is used is a question for whoever builds the wardrobe, so get the type and features written into the quotation.
A drawer box has a front, two sides, a back and a base. The front is the visible face and is adjusted last, so the gaps around it look even. The sides and back are joined to the front with screws, dowels or grooves, and this is where board choice shows up: fixings drive into the edges of the boards, and an edge that holds screws firmly keeps the box square for years, while a weak edge lets the corners loosen. Plywood's cross-laminated layers are good at this. Edges should be clean and smooth, because drawer sides touch your clothes every day and a rough edge snags knitwear. Depth is the other choice. A shallow drawer suits small items you want to see at a glance, such as socks, belts and accessories. A deep drawer holds bulky knitwear or towels, but it is heavy once filled and needs a stronger runner. Match the drawer box to the cabinet depth so the runners have room to work.
The base is the part that carries everything you put in the drawer, so it deserves more attention than it normally gets. A common good practice is a thin plywood base set into a groove cut round the front, sides and back, so the load is spread along four edges rather than carried by a few fixings. JIYU's 6mm plywood is meant for drawer bottoms and back panels, with 18mm used for the main structure. The most common failure is a base that slowly bows under folded jeans until the drawer scrapes the one below, so for a wide drawer ask the carpenter whether a centre support or a thicker base is needed. Humidity matters too. Drawers close to the floor sit in the dampest air, and a raw base edge draws moisture, so ask for the edges to be sealed. Plywood is stable across its layers, and moisture blistering caused by a manufacturing defect is among the faults our 10-year limited warranty covers.
Think about what will actually go in, drawer by drawer. Socks, underwear and accessories are light but numerous, so they need dividers more than strength. T-shirts are light but bulky. Jeans, knitwear and towels are heavy, and they belong in the lower drawers, with runners chosen for it. The top drawer at chest height gets the most daily use, so it should feel the smoothest. Rather than trust a general promise of heavy duty, ask the carpenter to name the runner's rated load in writing and compare it with what you plan to store. Keep in mind that a deep, wide drawer carries more than a shallow one, even when the clothes inside look similar. Check the layout too: the drawer pull should not catch a hinged door beside it, and the front should clear any hanging rail above. If you are still deciding what goes where, our wardrobe interior guide helps you sort the zones first.
Test them loaded, not empty. Before handover, ask to put real folded clothes in each drawer, or at least a stack of heavy items, and then run through a short routine. Pull each drawer fully open and push it fully closed several times: it should glide evenly, stop without banging and not rub the sides. With the drawer loaded, press down on the base near the front and listen for creaks. Check that the soft-close engages every time, that the full-extension runner really reaches the back, and that the gaps around each drawer front are even and line up with the neighbours. Lift the drawer out and re-seat it if it is the removable type. Look for sharp or rough edges inside. Confirm the wardrobe stands level, because a leaning cabinet makes drawers drift open or shut. Then check again after the first stretch of rainy weather, and report any change in the drawer while the warranty applies.
Are soft-close runners worth having on wardrobe drawers?
They stop drawers banging shut, which matters in a bedroom at night, and they protect the box joints from repeated impact. They add moving parts, so ask for them to be matched to the weight the drawer will carry.
Should wardrobe drawers have full-extension runners?
For deep drawers, yes, because you can reach the back without pulling out everything in front. For shallow drawers holding small items, partial extension is usually enough. Ask which one is in the quotation.
What are wardrobe drawer bottoms made of at JIYU?
JIYU uses 6mm ENF-grade plywood for drawer bottoms and back panels, with 18mm for the main structure. ENF means formaldehyde release of no more than 0.025 mg/m³ under GB/T 39600-2021, and a sample we submitted measured 0.022 mg/m³ in report JC26-WT0087.
What usually goes wrong with wardrobe drawers over time?
Three things: a base that sags under heavy clothes, runner screws working loose from a weak edge, and drawer fronts drifting out of line. Specifying the base, the fixings and the runner load at the start prevents most of them.
