Compressed mattresses are not a new category of mattress but rather a specific form of spring mattress that has undergone special processing. The primary objective is to compress the springs, significantly reducing the mattress's thickness to save storage space. Selecting a mattress for compression is not arbitrary; there are specific requirements regarding spring specifications.
For Bonnell (interconnected) spring mattresses, compression criteria are strict: individual springs must meet specifications of 2.15mm wire gauge, 4.5 active turns, and a 7.4cm diameter, while the total mattress height must be kept under 19cm to be suitable for compression.
Pocket spring mattresses have similar requirements: individual springs must feature a 1.8mm wire gauge, 4.5 active turns, and a 7.4cm diameter, with a total mattress height not exceeding 19cm. If a spring mattress exceeds these standards, attempting compression can cause the spring unit to deform due to uneven pressure distribution, thereby compromising the mattress's performance.
In summary, not all spring mattresses are suitable for compression; the process requires specific compatibility regarding spring structure and mattress height. Mattresses exceeding 19cm in height may lose their original comfort and stability after compression, so the feasibility of compression should be carefully considered when making a selection.
