Our Cook Mattress is designed with a 21cm Pocket Spring Construction system. Bonnell spring systems are created with an hourglass shape, being wider at the bottom and top. The springs are interconnected with a metal mesh, creating a durable, affordable and traditional feeling mattress without compromising on essential comfort.
The Cook mattress is designed with longevity and freshness at its forefront, with a breathable mesh shell surrounding the outer layer of the Core. This design allows for maximum airflow, transferring moisture and heat formed whilst sleeping. A mesh shell helps to create a fresh, healthier mattress for longer-lasting, more restorative nights' sleep for years to come.
The Cook mattress is finished with a 3cm deep pillowed topper. The pillowed finish provides a cosy and comfortable top layer for ultimate relaxation. Our Cook mattress topper means luxurious feeling sleep, without breaking the bank.
The Cook Mattress arrives at your door conveniently in a Flatpack Co. box. Our innovative packaging is significantly smaller than traditional mattresses, merging vacuum packing and a rolled design. This allows for easy movement upstairs, round tricky corners or through smaller door frames.

Kirsty was responsive, friendly and informative. Can fault her communication and support
Thanks Amy! So glad Kirsty was helpful - she's just recently started in customer service so we'll definitely share this kind review with her :) -Cam
This is hands down the best value mattress around. Its well made, comfortable and exactly what i was looking for, at a far better price than anything else i could see. Delivery was speedy, I fully recommend the Flatpack Co !
Judy... thank you. Really appreciate you spreading the word! -Cam
Amazed how the mattress expanded from packing. Very comfy . Great service
Lovely! It is a super fun unboxing :) Glad it's comfy + service was smooth. -Cam
I was amazed at how it expanded. I had to wait for someone to help me put it on my bed as I have a hernia and cant lift anything. So it sat looking at me for a week!! I am so please at how comfy it is and the price was very reasonable
Awesome Jennifer! It is such a fun experience watching it expand. Glad you had a friend to help and now a comfy bed too! - Cam
Easy to put together and like the mattress vac pack!
Even though this is the firmest out of the options it has been sooo comfy so far, super happy with my choice and would definitely recommend:)
Very surprised that a mattress folded up could pop out to be perfect 👌 this will be for our guest room and I’m sure there will be no complaints
Great mattress! Sleeping so much better!
