Spring mattress core FORTE model Forte_NX120 for 120 x 200 cm beds (self-assembly)

FORTE mattress core Forte_NX120 sized 120 x 200 cm is a spring support unit intended as an internal insert for beds and mattresses. Supplied for self-assembly, this spring system forms the structural support layer and is suitable for replacing an existing core or creating a new mattress or upholstered bed base. The unit is designed to be fitted inside a mattress casing, upholstered frame or platform where a resilient spring layer is required.

Advantages

This spring mattress core delivers consistent support across the sleep surface thanks to a structured coil system. Supplied as a self-assembly unit, it allows flexible installation in a variety of mattress constructions and bed frames. The product provides the primary load-bearing layer without added upholstery, enabling users or manufacturers to adapt comfort layers, padding and covers to specific firmness or comfort requirements.

Suitable for

• Replacing the internal spring core of a 120 x 200 cm mattress
• Building a custom mattress or reupholstering an existing mattress
• Using as the internal support layer for an upholstered bed base or platform
• Workshop or small-scale mattress production where a separate spring unit is required

When it may not be suitable

This product is a bare spring unit without upholstery layers, covers or comfort foams, so it is not a complete finished mattress as sold for immediate use on its own. Users expecting a fully finished sleep surface will need to add ticking, padding and comfort layers before use. It also requires basic self-assembly and fitting into a mattress casing or frame, so it may not be suitable for buyers who do not plan to perform installation or do not have access to upholstery services.

Key specifications

• Dimensions: designed for 120 x 200 cm mattress format
• Type of support: internal spring coil unit providing core support
• Intended use: internal insert for mattresses, bed bases or upholstered platforms
• Delivery form: supplied for self-assembly (core only, without upholstery layers)

How to use

Unpack the spring core carefully and check its dimensions against the mattress casing or bed frame. Position the unit inside the mattress ticking or frame so it sits flat and centrally aligned. Add required padding layers, upholstery foams and a mattress cover according to desired firmness and comfort. Ensure edges and seams are properly finished and that the assembled mattress is secured in the bed frame or platform before first use.

What to consider before purchase

• Measure the internal dimensions of the mattress casing or bed frame to confirm compatibility with a 120 x 200 cm core.
• Plan the additional upholstery layers (pads, foams, covers) you will need to achieve the desired comfort and protection.
• Confirm you have the tools or access to upholstery services required for installation and finishing.
• Understand that the product is a structural spring unit only and not a finished mattress ready for immediate sleeping.

Usage recommendations

For best results, combine the spring core with a suitable comfort foam or padding layer and a durable mattress cover to create a balanced sleep surface. If replacing an existing core, document the previous layer configuration to replicate preferred firmness. When in doubt about installation, consult a professional upholsterer or mattress technician to ensure correct fitting and edge finishing.
