Wilder King Size Bed Frame - Onyx

The Wilder king size bed frame pairs a low profile silhouette with a square headboard wrapped in Onyx Houseweave fabric. Measuring 1690mm wide, 2185mm deep and 1120mm high, it holds a standard UK king mattress and gives you a calm, simple base to build a bedroom around. The fabric carries a deep charcoal-toned Onyx look, while the pared-back shape keeps the focus on comfort and practicality rather than fuss. It is a bed frame made to work hard while staying quietly in the background.

We designed this bed frame for people who want more from their floor space. The gas lift mechanism raises the base to reveal a generous under bed storage area, useful for spare bedding, seasonal clothing or anything you would rather keep out of sight. Its minimalist form settles easily into modern rooms, smaller bedrooms and rented spaces alike, so you can dress it plainly or layer in colour and texture to suit your style. The square headboard also gives you a comfortable place to sit back and read.

The frame rests on sprung slats that flex with movement and support your mattress evenly night after night. The woven Onyx fabric is soft to the touch yet built for daily use, and the low profile design keeps the whole piece feeling grounded and unfussy. Assembly is required and the bed arrives across two boxes with a total weight of 50kg. To keep the fabric looking its best, wipe it with a damp cloth or lift away dust with a soft brush. Avoid soaking the material and let it dry fully before making the bed.

What is the Houseweave fabric like?

Houseweave is a woven upholstery fabric in an Onyx colourway, giving a deep charcoal-toned finish. It feels soft to the touch while standing up to everyday use. The plain weave keeps the look simple, so the bed frame sits easily alongside a wide mix of bedding, throws and room styles.

How does the under bed storage work?

A gas lift mechanism raises the base upward to open a large storage space beneath the mattress. It holds spare bedding, pillows, clothing or seasonal items you want out of sight. The lift takes the weight for you, so raising and lowering the base stays smooth and controlled during everyday use.

What size mattress does it need?

This is a king size bed frame, so it takes a standard UK king mattress measuring 1500mm by 2000mm. The external frame measures 1690mm wide and 2185mm deep, allowing room for the headboard and side rails around the mattress. A double size is also available within the Wilder range.

How do I clean and care for it?

Wipe the fabric with a slightly damp cloth or lift away dust with a soft brush. Avoid soaking the material and never scrub hard, as this can mark the weave. Let any damp areas dry fully before remaking the bed, and brush gently on a regular basis to keep the surface fresh.

Is assembly difficult?

Full assembly is required and the bed frame arrives in two boxes with a total weight of 50kg. We recommend two people to handle the parts and fit the gas lift base safely. Follow the supplied instructions in order and keep all fixings to hand so the frame comes together securely.
