For storage bed base wholesale in North America, the format decides more than the price: US and Canadian stores sell three kinds of bed support (the box spring, the platform bed and the storage base), and each one changes what you order, how it ships and which rules apply. A Turkish storage base with a gas-lift top replaces both the box spring and the bed frame, so it competes with platform storage beds rather than with foundations. The catch is size: our bases are built for metric mattresses, and US and Canadian bedding is sold in inches.
This guide is written by ellda mobilya, a furniture manufacturer in Kayseri, Türkiye, producing sofa sets, corner sofas, bed base sets and mattresses since 2010. It is aimed at US and Canadian retailers, importers and distributors who are deciding which bed format to buy from Türkiye. Duty and regulation facts are as of November 2026 (last verified 2026-11-06); check the current rate with your customs broker before you order.
Box spring, platform or storage base: what is the difference?
A box spring (also sold as a foundation) is a fabric-covered frame, with springs or a rigid deck, that sits on a separate metal or wooden bed frame and raises the mattress. A low-profile foundation does the same job with less height. Neither stores anything, and the headboard is usually bought separately and bolted to the frame.
A platform bed is a frame with a solid or slatted deck that holds the mattress directly, so no box spring is needed. Storage platform beds add drawers under the deck. Most are shipped flat and assembled by the customer.
A storage base, which Turkish catalogues call a baza, is an upholstered box that holds the mattress and opens to a storage space underneath, often on gas struts. In a Turkish bed base set it comes with a matching upholstered headboard. Our guide to the Turkish baza explains the terms in more detail.
| Format | What the retailer sells | Storage | Typical headboard | Where it sits in a North American range |
|---|---|---|---|---|
| Box spring or foundation | Foundation plus a separate bed frame | None | Separate, bolted on | Entry price, often sold with the mattress |
| Platform bed | One frame with a deck | Drawers on some models | Part of the frame or separate | Flat-packed, mid-market |
| Storage base (baza) | Upholstered base plus matching headboard | Whole base, lift-up top | Upholstered, same fabric | Design-led bedroom set |
The practical difference for an importer: a box spring is a commodity that domestic mattress makers already supply, while an upholstered storage base with a tall headboard is a furniture piece. That is where a Turkish manufacturer has something to offer that a local mattress supplier usually does not.
Why does size come first for US and Canadian buyers?
Bedding in the US and Canada is sold in inches: a queen is 60 × 80 in (about 152 × 203 cm) and a king 76 × 80 in (about 193 × 203 cm). Our bed base sets are made for 90 × 200, 160 × 200 and 180 × 200 cm mattresses, and none of those is a North American size. A 160 cm base is about 8 cm wider and 3 cm shorter than a queen; a 180 cm base is about 13 cm narrower than a king. A storage base is a closed box, so the mattress has to fit it closely.
You have three ways to handle this, and the right one depends on the country:
- Ask for a North American size. Name the model and the size (queen or king, in inches and centimetres) in your enquiry. Whether that model can be made in that size is confirmed in the quote; we do not list inch sizes in the catalogue.
- Sell metric sets. Base and mattress come from the same factory, so they fit each other. This works in Canada, where Turkish mattresses can be imported with the bases. It does not work in the US, where we do not quote mattresses (see the duty section below).
- Lead with the headboard. Headboards in the catalogue run from 90 cm to 270 cm wide. A wide, tall headboard is the part a shopper sees, so it can carry a bedroom display even when the base underneath has to be resized.
For the full size comparison, see mattress sizes by country and storage bed base sizes.
How do US and Canadian duties treat a bed base?
The two countries treat the same storage base very differently. Both start from the classification: an upholstered storage base may be classified as a mattress support under heading 9404 or as bedroom furniture under 9403, depending on how it is built. Our HS codes guide explains the choice; your broker makes it.
United States, as of November 2026 (last verified 2026-11-06):
- Section 232 does not reach bed bases. The 25% duty on timber derivatives covers upholstered seats with wooden frames, and the planned rise to 30% is set for 1 January 2027 (White House proclamation of 31 December 2025). Bases and headboards sit outside it. A storage pouf sold with the set is a seat, though, so ask your broker how it is classified. Our Section 232 tracker follows the rate.
- Section 301 does. Since 24 July 2026, goods of Türkiye pay an additional 12.5% duty under heading 9903.05.79, with an exclusion for goods covered by listed Section 232 programmes (CBP CSMS #69326983). For a bed base, plan on the MFN rate in the Harmonized Tariff Schedule plus 12.5%.
- Mattresses from Türkiye are under an antidumping order (Federal Register, May 2021), which the USITC voted on 13 October 2026 to keep. For the US we quote bases and headboards only. If a shipment carries anything mattress-like, ask your broker to check it against the order's scope.
Canada, as of November 2026 (last verified 2026-11-06):
- No free trade agreement with Türkiye. Turkish goods pay the MFN rate in the Canadian Customs Tariff; Global Affairs Canada's list of agreements does not include one.
- No trade remedy on Turkish beds or seating found. CBSA's measures on upholstered domestic seating cover China and Vietnam, and its measure on mattresses covers China. Neither names Türkiye.
- Matched sets are possible. Because no Canadian measure covers Turkish mattresses, a Canadian buyer can order bases and mattresses together. See our Canada import guide for the entry steps.
Which safety and labelling rules touch a bed order?
US flammability. 16 CFR 1640 covers upholstered seating, and CPSC lists a mattress, a foundation and bedding products as outside its scope (CPSC FAQ). Ask your compliance adviser whether an upholstered storage base counts as a foundation, and whether a pouf in the set is seating. Our 16 CFR 1640 guide covers the label.
US mattress sets. Under 16 CFR 1633, a mattress set is a mattress and a foundation labelled for sale as a set, and a foundation can include box springs and other constructed frames (CPSC mattress guidance). If you plan to sell our base as the labelled foundation for a local mattress, raise it with your mattress supplier first, because the set is tested as a unit.
Canada. The Mattresses Regulations under the Canada Consumer Product Safety Act set a cigarette-ignition test for mattresses, so list them as a requirement if your order includes mattresses. Upholstered pieces also need a fibre-content label under the Textile Labelling Act (Competition Bureau guide); our Canadian labelling guide explains what goes on it.
We do not state compliance for any model here. Write the rule in your enquiry and it is confirmed or excluded in the quote.
Which format suits your business?
| Buyer | Format to look at | Watch out for |
|---|---|---|
| US furniture store adding a bedroom display | Storage base and headboard, resized to queen or king | Inch sizes; Section 301; pouf classification |
| US mattress retailer | Headboards and bases sold without our mattresses | The labelled mattress set under 16 CFR 1633 |
| Canadian furniture retailer | Metric sets of base plus mattress, or resized bases | Matching sheets and toppers to metric sizes |
| Canadian importer or distributor | Mixed load of sofas, bases and mattresses | Textile labels; MFN rates per tariff item |
A mixed load helps on this route. Upholstered bases fill a container by volume, and adding sofa sets or corner sofas lets a first order test more than one category in the same container.

How ellda handles bed base orders for the US and Canada
Our bed base sets are made in our 10,500 m² factory in Kayseri Organized Industrial Zone, where bases and headboards are upholstered and checked for dimensions, stitching, surfaces and the lift mechanism before packing. You can follow the steps on our production page. Export orders are packed for long-distance transport, and the loading plan comes with the quote.
For North American buyers we keep the invoice split by product group (base, headboard, pouf, mattress), which makes your broker's classification simpler. Price, minimum quantities, lead time, delivery terms, available sizes and what can be supplied for each rule you list are all stated in the quote. We work in English, Arabic and Turkish, and visits to the factory are by appointment. The step-by-step US process is in our US import guide.
Next step
Choose the format first, then the size: decide whether you are selling a storage base with a statement headboard, and whether it has to fit queen and king mattresses. Send the checklist through our wholesale page, or through the export page if you ship as an importer.
