If your current mattress feels a bit too firm or has started to lose its comfort, this 10cm deep microfiber topper is the simplest way to fix it. We’ve designed it with an extra-thick 4-inch fill to give you that sink-in feeling you usually only find in high-end hotels. It’s made from soft, breathable microfiber that doesn’t trap heat like memory foam, so you stay comfortable all night long. The elasticated straps are sturdy enough to keep it from sliding around, even if you move a lot in your sleep. It’s a practical, affordable way to make an old bed feel brand new again without the massive cost of a replacement mattress. Give it a good shake: This topper comes vacuum-packed to save on shipping space. When you first open it, it might look a bit flat—don't worry! Give it a really good shake and leave it on the bed for about a day or two. This lets the air get back into the fibers so it can reach its full 10cm fluffiness. Maintenance: If it starts to feel a bit flat after a few weeks of use, just give it another quick shake to redistribute the filling and it’ll be right back to normal.
