Nature's Sleep Cool IQ 10" Review 

Nature’s Sleep Cool IQ 10″ Review

Nature’s Sleep has been around since 2001. Some of the first products like the GhostBed proved incredibly popular. Since then, more mattresses and support pillows have been added to the range. The Nature’s Sleep Cool IQ is an ideal choice for those looking for premium memory foam construction and reliable support to alleviate neck and shoulder pain. With two high-density layers of memory foam, you can look forward to maximum comfort and a peaceful night when sleeping on this Nature’s Sleep mattress. 

Nature’s Sleep Cool IQ 10″ Overview 

Many memory foam mattresses boast at least three layers of material. As such, you’d be forgiven for thinking that the Cool IQ, with just two layers, offers inferior levels of support and cushioning. However, the high-density layers on offer here work overtime to provide you with superior performance, all night long. 

In the case of the 10-inch Cool IQ mattress, you benefit from a deep 7-inch Premium Support layer. This provides an effective base for the upper comfort layer. The 3-inch Cool IQ memory foam top layer is what delivers luxurious levels of comfort. This mattress isn’t as firm as other products on the market, but it’s a good choice for those looking for instant relief. 

Why Make the Switch? 

Even if you’ve had bad luck with memory foam mattresses in the past, the Nature’s Sleep Cool IQ is worth investing in. It strips things down to the basics, providing you with all the support you need to enjoy a restful night’s sleep. The thick base layer goes a long way in providing relief from pressure as you sleep. If you suffer from stiffness in the shoulders or neck, you’ll experience instant relief when using this mattress. 

However, it’s the Cool IQ layer that will make a real impression. Effortlessly conforming to your curves and contours, this mattress will help you drift off to pleasant dreams. For best results, you should combine the Cool IQ with a solid bed frame. 

The Nature’s Sleep Cool IQ isn’t the cheapest of memory foam mattresses, but it’s a good choice for those looking for effective relief from aches and pains. It’s also fairly low maintenance, with a removable cover making cleaning straightforward. 

The Science Behind the Nature’s Sleep Cool IQ 10″

The Cool IQ mattress from Nature’s Sleep is a go-to choice if you’re looking to reduce pressure on the shoulders, neck, and spine. Although not as effective as other mattresses, it will ensure your spine remains correctly aligned throughout the night. 

The open-cell design of this memory foam is what really sets the Cool IQ apart from the competition. Although dense, the memory foam won’t trap as much heat as other memory foam mattresses. This enhanced ventilation ensures that body heat is quickly dispersed. Even on stifling summer nights, this mattress will provide you with a cool sleeping surface. Although other mattresses boast an open-cell design, the cell structure here is particularly large. Don’t let a bad experience with mattresses boasting cooling technology put you off this premium product from Nature’s Sleep. 

Key Benefits of the Nature’s Sleep Cool IQ 10″

The Cool IQ from Nature’s Sleep isn’t for everyone. However, if you’re of average weight and prefer to sleep on your back or side, it’s a worthwhile option. Despite only having two layers of memory foam, the incredibly dense base layer means you can expect incredibly high levels of support. This base layer also delivers when it comes to motion isolation. If you’re opting for a Queen or King-sized Cool IQ Mattress, you’ll be able to reap the benefits of this motion isolation performance. 

The overall construction of this mattress is impressive. The large open-cell structure means you can expect even support across every inch of the surface. In other words, edge support is as consistent as what you can expect from the middle of the mattress. The high-quality materials also score top marks. The memory foam itself is very hard-wearing, with a 20-year warranty courtesy of the manufacturer. 

All materials are hypoallergenic, making them suitable for every sleeper. Meanwhile, the mattress is antimicrobial, meaning it’s unlikely you’ll encounter unpleasant odors and issues with bacterial buildup. A removable cover makes occasional maintenance incredibly easy, with the cotton-rich mattress slip suitable for machine washing and tumble dryers. 

The 3-inch comfort layer is fairly thick. However, without the inclusion of a transitional layer, you may encounter some issues with responsiveness. That being said, the advanced ventilation credentials of this mattress more than compensate for any shortcomings in this area. 


The Nature’s Sleep Cool IQ mattress features two individual layers of memory foam. A so-called Premium Support layer makes up the base, with a thickness of 7 inches. The upper Cool IQ is 3 inches thick. Both layers are made from CertiPUR-US certified memory foam. In addition to the main mattress itself, this product comes with a removable cover. Made from 80% cotton and 20% polyester, this cover is easy to clean and maintain. It’s suitable for cleaning in a washing machine on a cold cycle and can be placed in a tumble dryer on a low setting. 

Available Sizes

The 10-inch Cool IQ mattress from Nature’s Sleep is available in a range of sizes. You’ll find standard Twin and Full sizes, as well as Queen and King sizes to accommodate larger bed frames. The mattress can be purchased on its own, as well as alongside a foundation when buying from select manufacturers.

The Verdict

The Nature’s Sleep Cool IQ 10-inch mattress is one of the more reliable memory foam products on the market. Some consumers may be put off by the lack of a transitional layer, but it’s the two-tiered design that makes this mattress so effective. Remember, the base layer is incredibly thick, with 7-inches of high-density foam providing you with an incredibly reliable foundation. The upper layer is also more than thick enough to cushion your body and conform to your curves. 

The open-cell structure of this memory foam is also superior to the materials found in other all-foam mattresses. The larger cells allow for increased ventilation, making it a good choice for warmer nights and hot sleepers. This improved airflow also means you’ll encounter fewer issues with moisture and odor buildup. Furthermore, the removable cover makes this a low-maintenance option that’s easy to keep in tip-top condition. 

The Cool IQ from Nature’s Sleep isn’t the cheapest all-foam mattress on the market, but it’s far from expensive. You also have a good range of sizes to choose from here, meaning you can quickly transform everything from a modest twin-size frame to a King-size bed in a master bedroom. If you’re seeking medium levels of firmness, this mattress is hard to beat. However, heavier users looking for the added support of a transitional layer may be better off considering alternative products.
