Need a bit more height under your bed for storage bins? Want your sofa or desk to be a more comfortable height? These adjustable furniture risers are a simple and solid solution. You get four in a pack. Each riser has a clever screw-clamp mechanism that lets you adjust the height from 6cm up to 8cm. They can fit square or round furniture legs with a diameter (or width) between 1cm and 5cm – just loosen the screw, slide the leg into the U-shaped bracket, and tighten it firmly for a secure, non-slip hold. They're made from a combination of strong plastic and iron, and can support an impressive maximum weight of 300kg in total. The bottom has a soft felt pad to protect your floors from scratches and reduce noise when moving furniture. Perfect for raising beds, sofas, tables, desks, or chairs. It's a much cheaper alternative to buying new furniture and is great for creating under-bed storage space, making cleaning easier, or just improving ergonomics. Easy to install and remove.
