This mattress is super comfortable with great support. My wife has bad back ache normally in the morning and since we got this mattress it has eased off loads. The mattress is very big and heavy and doesnt come rolled up like alot of these new fad mattresses. Wpuld I recommend it, yes 100%.

I've only had the memory cool 3000 mattress for a few weeks but I'm sleeping much better than before with less tossing and turning. It's definitely a cooler mattress, I'm never hot on it. It's like a 5 star hotel bed and I find it comforting to lay on it.

Frequently asked questions

What materials are used in the Memory Cool 3000 mattress?
The Memory Cool 3000 mattress features CoolMemory foam, which provides body moulding and pressure relief, as well as a pocket sprung system, where each spring is individually encapsulated in fabric for independent movement and support.
What impact does the micro quilted finish have on the mattress's comfort?
The micro quilted finish contributes to the mattress's comfort by securing the fabric and fillings together. This stitching creates a soft and patterned comfort layer, enhancing the overall sensation while lying on it.
Is the Memory Cool 3000 mattress suitable for all sleeping positions?
Yes, the combination of memory foam and pocket springs makes the Memory Cool 3000 mattress suitable for all sleeping positions, as it provides support and comfort tailored to the sleeper's body shape.
What is the benefit of the attached handles on the mattress?
The attached handles on the border of the mattress make it easier to rotate and turn, ensuring you can maintain the mattress properly for optimal comfort and longevity.
Do I need to turn the Memory Cool 3000 mattress regularly?
This mattress is designed to be one-sided, so there is no need to turn it, but it is recommended to rotate it occasionally to promote even wear.
What does the pillow top effect mean for comfort?
The pillow top effect gives the mattress a plush feel that looks separate from the main body of the mattress, but is actually attached with a hidden return, enhancing comfort with soft fillings.
How does the pocket sprung system enhance sleep quality?
The pocket sprung system allows each spring to move independently, which helps to prevent motion transfer between partners and ensures a quieter night's sleep.
Are there any features to help with air circulation in the mattress?
Yes, the Memory Cool 3000 includes vents located on the border, which help the mattress to breathe and release damp air, promoting a fresher sleeping environment.
What does the Source 2 flammability rating indicate?
The Source 2 Domestic Flammability Rating indicates that the mattress meets low hazard standards for general domestic use, ensuring safety while you sleep.
What happens to the memory foam after it's been used?
The memory foam within the Memory Cool 3000 is designed to return to its initial shape after each use, ensuring that it maintains its form and delivers reliable comfort consistently over time.

60-night sleep trial: exchanges only, not refunds. Activated by purchasing a mattress protector at the point of order. Request your exchange between nights 30 and 60 of the trial; a £50 exchange fee applies. Full terms.
