It gives the air system something firm to sit on, and because it's much thinner than a standard mattress, it keeps the bed surface low.\u003c\/p\u003e\n\u003cp\u003eDispatched from our Australian supplier's NSW warehouse, usually within 2-7 business days.\u003c\/p\u003e\n\u003ch3\u003eWhy Use an Underlay Instead of a Mattress\u003c\/h3\u003e\n\u003cp\u003eAir overlays are often laid on top of an ordinary foam mattress. That stacks two layers together and can leave the sleeping surface much higher than the bed was designed for, which makes getting in and out harder and puts the top of the bed rails closer to the mattress. Swapping the full mattress for this 5cm underlay brings the height back down.\u003c\/p\u003e\n\u003cp\u003eIt also adds support under the air cells. If the power goes out, the system develops a fault, or the backrest is raised for a long time, the foam stops the air mattress from \"bottoming out\" onto the bed base.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e5cm medium-density foam.\u003c\/strong\u003e Durable support under an alternating air overlay or air mattress.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeeps the bed low.\u003c\/strong\u003e Much thinner than a standard mattress, which helps where there's a risk of falls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupport if the air system loses pressure.\u003c\/strong\u003e Helps stop the air mattress bottoming out during a power cut or fault.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits standard sizes.\u003c\/strong\u003e Made in single and king single to suit standard air mattresses and beds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater resistant, vapour permeable cover.\u003c\/strong\u003e Protects the foam and lets moisture vapour escape.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-month warranty.\u003c\/strong\u003e Covered for a year from purchase.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eIs the Cobalt Mattress Underlay Right for You?\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eIt usually suits you if you:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003euse an alternating air overlay, like the \u003ca href=\"\/products\/5-inch-single-alternating-overlay-air-mattress\"\u003e5\" Single Alternating Overlay Air Mattress\u003c\/a\u003e we stock, and want to keep the bed height down\u003c\/li\u003e\n\u003cli\u003ewant a backup layer of foam under an air system\u003c\/li\u003e\n\u003cli\u003eare replacing a full foam mattress under an air overlay\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eGood to know before you order:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIt's not a mattress.
