The welded PU mattress cover has its seams fused by high-frequency (HF) or ultrasonic welding instead of stitching. With no thread and no needle holes along the seams, the PU barrier is continuous, so blood, infusion fluids and urine have no path into the mattress core through the joins. It is made to your dimensions for hospital beds, stretchers and other medical mattresses and pads.
A stitched seam joins two panels with thread, and every stitch pierces the coated fabric. Seam tape or sealing can close those holes, but the seam remains the most likely path for fluid into the core.
A welded seam is fused instead. HF welding heats the coating with radio-frequency energy, ultrasonic welding with high-frequency vibration, and the two layers become one, with no thread and no holes.
Welding suits covers that are disinfected often and must keep fluids out of the core over a long service life. Our stitched PU hospital mattress cover remains the choice where maximum stretch and softness matter most. Tell us the use and we will recommend the construction.
Send the length, width and depth of the mattress or pad, the shape of the corners, any cut-outs, the closure you need and the quantity. Tell us how the cover will be cleaned and disinfected, so the coating and seams are specified for it.
We choose HF or ultrasonic welding per construction. A sample run is made before production, so you can check the fit and the seams on your own mattress, and covers can be produced under your brand.

A mattress cover whose seams are joined by welding instead of sewing. High-frequency (HF) or ultrasonic welding fuses the PU-coated layers together, so the seams have no thread and no needle holes.
For keeping fluids out, usually yes: a welded seam is a continuous barrier, while every stitch is a hole that has to be sealed. A stitched cover can still be the better choice where stretch and softness matter most.
HF welding heats the coating with radio-frequency energy between two electrodes; ultrasonic welding generates the heat at the joint with high-frequency vibration. Both fuse the layers without thread. We choose the method per construction.
