Mattress Bags from Our Factory: Six Standard Sizes, Custom Beyond — Here Is What You Can Order

The six standard sizes

Mattress retail is one of the most standardised furniture categories in the world: a Queen mattress sold in Hamburg and a Queen sold in Houston are built to the same nominal footprint. That standardisation is what makes a six-size programme viable — instead of listing dozens of bag patterns, the range follows the bed sizes the market already agrees on.

The programme covers the six sizes that account for nearly all retail and moving volume. Each bag is produced to the nominal mattress footprint, and the sizing logic has been stable for years — which is exactly why it works for replenishment: your stock-keeping does not change from one order to the next.

For most distributors, the practical question is not “which sizes exist” but “which two or three sizes move fastest in my market” — Queen and Twin XL in university towns, King and Cal King in premium retail. You can start the programme on those sizes alone; the minimum applies per size, not across the range.

There is a second benefit to a fixed size ladder: it makes replenishment boring, in the good sense. A bag for a Queen mattress produced this quarter matches the one produced last quarter, because the size is written into the order rather than re-derived each time. When your own customers ask for “the same bags as the last shipment”, the answer is a spec reference, not a search.

Custom sizes beyond the standard

The standard six assume a conventional mattress height. When the bed does not fit that assumption, the bag goes custom — same material, same seam process, your dimensions.

Custom sizing follows the same process and the same minimum as the standard programme. The difference is only the cutting pattern — and it is often the custom orders, the ones no competitor will quote, that keep a buyer from shopping the line around.

The starting point for a custom size is simply the bed’s three dimensions — length, width and full height, measured on the product itself rather than taken from a price list. From those numbers we work backwards to the bag pattern and confirm it with a sample before production.

Height is the dimension buyers forget most often. Length and width are printed on every spec sheet; height is not, and it is the one that moves — a top padding layer, a built-in base, a topper added at retail. When a bag is ordered on footprint alone, the height is guessed, and a guessed height is how bags end up half-fitted on the showroom floor. Measuring takes two minutes; re-ordering takes two weeks.

Material and seams: what the bag is made of

The film is always virgin LDPE. Not recycled, not a blend. A mattress spends days in direct contact with this bag, and odour transfer is a return reason on its own — virgin material removes that risk before it exists.

The seams are heat-sealed. The failure point of a mattress bag is rarely the film; it is the corners, because when two movers carry a mattress diagonally, the bag’s corners take the full tension of the load. A full-perimeter heat seal, with no pinholes, is what keeps that tension off the film.

Handles are optional. With handles, the carry force moves from the corners to the handles, which makes single-person cornering and stair work noticeably easier. Delivery-heavy buyers — moving companies, last-mile furniture logistics — add them as a rule.

One more practical property: bags ship flat-packed. A pallet of flat bags covers a season of mattress deliveries in a fraction of the container volume that rigid packaging would take, which is why the bag is packed flat and folded — freight is charged on volume, and volume is where this product is quietly efficient.

Gauge follows the journey, not the price list: shorter retail routes run lighter film, long-haul export with multiple handling points runs heavier. Both are part of the specification you confirm, which is why we ask where the bags will be used before quoting — the same question that starts every made-to-order product in our range.

Options you choose per programme

Printing runs on the same production pass as bag-making, so a printed programme adds no separate process. Retailers print brand, size chart and barcode — warehouse staff verify without opening the bag. Moving companies print logo and phone number — every delivery is a visible touchpoint in hallways and lifts. E-commerce mattresses print the size callout where the instruction card would be.

Clear and coloured film serve different shelves: clear keeps receiving inspections fast, coloured hides the contents for direct-to-shelf programmes.

The print workflow has two checkpoints. First, we confirm the print repeat against your bag size — artwork laid out for a Queen bag does not always sit right on a Twin, and the repeat is checked size by size before anything runs. Second, a colour proof is approved before production. Both checkpoints exist because the cheapest place to fix a print error is on screen, and the most expensive is on a pallet.

Minimums, containers and lead time

Minimum: 1000 kg per size. Two or three sizes is a normal starting order — the fastest movers first, the rest added as the programme proves out.

Containers: sizes mix in one container in your sales ratio. You do not need to fill a container per size; you need to fill one container across the range.

Lead time: 30+ days from confirmed specification — and “specification” includes the print artwork. If the artwork is late, the order is late. Q4 moving peak and spring retail resets are planned against this calendar, not against stock levels.

Mixed containers are packed deliberately: each size is counted and labelled against the packing list, so receiving at your warehouse is a count-and-put-away job rather than an unpack-and-identify one. If your programme runs printed bags in several sizes, the packing list follows the same size order as your artwork reference — small details, but they shorten the receiving line.

Samples and how an order runs

The sample step exists so the fit question is answered on your bench, with your product, before the container is booked. Once the sample is confirmed, the specification is written into the order and repeats against it — a repeat order is produced to the same frozen spec, which is what lets you promise your own customers “same as last time” without re-testing every batch.

That is the whole loop: dimensions in, sample out, spec frozen, repeat orders produced against the frozen spec. It is a deliberately short chain — short enough that a first order and a re-order follow the same path, and nothing in the programme depends on memory or goodwill. The sections below summarise what that loop delivers for a buyer running it season after season.
