Mattress spring frames

The first bonnell spring was made as early as 1808 and they are very popular even now. We are sure that your choice of the spring as a supporting element is a good one thanks to the excellent strength, springiness and sanitary properties of the basic material – high-quality steel wire.

Spring cores consisting of separate bonnell springs are made in two basic versions:

• Bonnell
• Minibonnell

Spring frames sizes:

• Regular mattress (e.g. 195x75x11 cm)
• Large “airports” (e.g. 195x135x11 cm)
• Smaller sizes
• Atypical sizes (e. g., corner frames)
• Individual as requested by the customer.

Spring frame ends:
Frameless
Woven with a coil at the shorter ends
With one frame
With two frames.
Diameter of the wire:
2.20 mm (Bonnell, Minibonnell)
2.30 mm (Bonnell)
2.40 mm (Bonnell)
Spring frames can be also made of less frequent wire diameters (e. g. 2.00mm, 2.15mm), if required by a customer.
Tolerances specified by manufacturers are taken into account with diameters of the wire bought.
Spring frame versions:
Bonnell
Spring height: 80 - 150 mm
Spring frames with max. height of 150 mm cannot be delivered rolled in bundles, only in bulk.
4 to 6 coil turns with spring diameter of 83 - 92 mm.
Suspension wire 2.20 mm, 2.30 mm, 2.40 mm in diameter or another diameter, if agreed, (e.g. 2.00 mm, 2.15 mm).

Spring frames are supplied in rolls in bundles with 5 – 50 pcs in each bundle (depending on the size and weight of separate cores):
The advantage is lower freight costs, better handling and storability.
Apart from the standard versions, the customer can choose from alternative versions of similar spring frame types:
according to the wire used and the design,
according to the number of springs (number of springs depending on the spring diameter),
according to the spring core ends,
according to the spring frame sizes.
The final price of the spring frame is based on the version chosen.
