Features

• Powerful and Long-lasting Support：With this ultra-strong and high-quality plywood support board, you can easily and quickly improve the condition of a sagging sofa. It is especially suitable for sofas with a sagging frame, sunken cushions, or worn-out springs, adding extra support and comfort. The support board is 21.5 inches wide, covering a larger area and providing more sufficient support.
• High-quality and Durable Material：Unlike products from other brands that use medium-density fiberboard (MDF) or particle board, this support board is made of high-quality plywood with a thickness of 0.43 inches. It is inherently stronger and more durable, capable of supporting up to 400 pounds, ensuring stable use over a long period.
• Anti-slip Fixing Design：Hundreds of anti-slip PVC dots are set on the bottom of the board, specially designed to keep the support board firmly in place on the sofa. These anti-slip dots can effectively grip the sofa frame, preventing the board from shifting during daily use. Additionally, the individual board panels have rounded corners, reducing the likelihood of the sofa cover being torn and protecting the appearance of the sofa.
• Simple and Quick Installation：The installation process is extremely easy and can be completed in just a few minutes. First, simply remove the cushions from the sofa, unfold the support board, and place it on the sofa frame with the anti-slip dots facing down, making its width match the sofa frame. Finally, put the cushions back on top of the support board.
• Flexible and Universal Fit：The support board is available in standard sofa sizes, which can perfectly fit most sofas. Meanwhile, it has the characteristics of being foldable and stackable, allowing for flexible adjustment to fit loveseats or smaller sofas. Before purchasing, it is recommended to measure the width of the sofa seat from the left inner armrest to the right inner armrest to select the appropriate size. This support board is 78 inches long.
• Economical and Practical Choice：By using this support board to repair a sagging sofa, you can avoid the high cost of replacing a new sofa due to damage. It is an affordable solution that can restore the normal use function and comfort of the sofa, as well as extend its service life, saving costs for users.
• Thoughtful Usage Suggestions：To ensure that you purchase the appropriate size of the support board, it is necessary to accurately measure the relevant dimensions of the sofa before buying. Following the correct installation steps can make the support board function better and enhance the user experience. If you encounter any problems during use, you can refer to the product instructions or contact the after-sales service for assistance.
