The 4G Aircool Ultra Memory Foam Mattress is a medium soft mattress with cooling technology in the foam and the mattress cover - ideal for sleepers who enjoy the soft, enveloping sensation of memory foam but find that the traditional stuff makes them too hot.

The top layer of memory foam is made of innovative 4G Aircool Memory Foam, which is exclusive to Memory Foam Warehouse. The 4G Aircool memory foam provides the luxurious comfort and support of traditional memory foam, while increasing airflow through the mattress by up to 95%. This means excess body heat and moisture is removed naturally for a fresher, cooler and more hygienic sleep every single night.

Beneath is a second layer of slightly firmer memory foam for support, and thirdly a durable reflex foam base. This deep base layer has grooves engineered into it. These are designed around the major pressure points to deliver support and pressure-relief where you need it most.

The 4G range features a eucalyptus infused mattress covers that are extremely soft and ideal for sensitive skin as they absorb moisture and prevent bacteria formation.

The 100% eucalyptus fibres are natural and extracted from eucalyptus wood specifically grown in sustainable plantations. Production of the fibre is environmentally friendly throughout the process.

The Ultra 4G Aircool Memory Foam Mattress is delivered rolled, so you can get it to your bedroom easily.
