What the Sleep Expert thinks...
"If support is your main priority, the Space 4000 really stands out. It has a firmer feel that helps keep promote spinal alignment, which can make a big difference to some people that wake up with aches. What’s nice is the CoolGel layer, it stops it feeling too ‘hard’ or warm, adding a cooler, more comfortable surface while still delivering that orthopaedic support."

I'm not sure how you can sell a mattress this good for this price! Be warned though, make sure you're ready when you cut the packaging as it really does explode out of there!

Really comfortable mattress, I chose the right level of firmness and I am happy with that; obviously quite heavy (47kg) but it's because of the quality of the product (4000 springs) so I wouldn't change anything of this superb mattress.
