⚡ At a Glance

  • Best for: Homeowners replacing worn slats on 4ft6 double beds who can measure and trim to fit

Sprung wooden slats shaped with a bow provide responsive support. Each slat measures 690mm long, 53mm wide and 8.5mm deep.


Restore Mattress Support - Thanks to sprung wooden construction

Sprung wood is manufactured to hold a bowed profile that flexes under weight, spreading load across the frame. The combination of depth and bowed shape yields progressive resistance rather than a rigid response.

A firmer, more even sleeping surface follows from replacing broken or sagging slats, helping to prolong mattress life and reduce pressure points.

Custom Fit Made Easy - With trim-to-size option

Slats arrive at 690mm length and can be shortened on site or by request to match existing slat channels. Sellers invite messages for custom length guidance to ensure correct fit.

Measure the current slat length and width, then trim or request a custom length so the slats sit neatly in the frame without excess movement.

Simple Repair, Sturdy Result - With durable sprung wood material

Manufactured from durable sprung wood that retains a bowed profile, the slats combine flexibility with structural strength. Width and thickness are set to fit typical slat holders while resisting everyday compression.

Quick replacement of damaged slats returns reliable support and comfort, making it a practical alternative to replacing the whole bed frame.
