Description

Technical Field

[0001] This utility model relates to the field of bed equipment technology, and in particular to a convenient fitted sheet mattress replacement device based on a zipper. Background Technology

[0002] A fitted sheet is a protective fabric cover used to cover the outer surface of a mattress. It has bound edges to ensure a close fit, preventing dust and stains and improving sleep comfort. Fitted sheets are typically made of elastic fabric or have a matching fastening mechanism to securely cover the mattress and prevent shifting during use. Compared to traditional sheets, fitted sheets are easier to lay out, less prone to wrinkling, keep the bed surface clean and smooth, reduce mattress wear, and extend the mattress's lifespan.

[0003] Traditional fitted sheets with elastic bands around the four sides will gradually age and lose elasticity after repeated stretching and washing. This will cause them to loosen and deform, making it impossible for the fitted sheet to continue to fit the mattress surface. They are prone to slipping, curling, or wrinkling, which will affect the stability and comfort of sleep. The elastic bands may even break or deform after aging, which not only shortens the overall lifespan of the fitted sheet, but also requires users to frequently adjust the position or even replace it in advance, bringing additional cost and inconvenience. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in existing mattress protectors with elastic bands around the four sides, after long-term repeated stretching and washing, the elastic bands gradually age, their elasticity significantly decreases, and they become loose and deformed, making it impossible for the mattress protector to continue to fit the mattress surface. This can easily cause slippage, warping, or wrinkling, thus affecting the stability and comfort of sleep. The elastic bands may even break or deform after aging. Therefore, this invention proposes a convenient mattress protector based on a zipper for easy mattress replacement.
