Very good mattress; bought a second one for guest bed as first so good. Feels slightly firmer on a platform bed than on a slatted base bed but still extremely comfortable. Recommend. p.s. Delivery service guys and shop advice excellent too.

Disappointed with this mattress, it’s very comfortable but the memory foam makes us far to hot, we have been sleeping with the summer duvet on but still wake up during the night feeling too hot. Am dreading next summer as wont be able to sleep well. We were told when we bought the mattress that is was a climate control , ie cool in summer etc but this has not been the case , just makes feel too hot. We should have returned it but we were away and went past the the 6 weeks return date .

A great mattress exactly as described . Extremely firm and comfortable . Mattressman delivered exactly to schedule and their deliverymen could not be faulted. I have no hesitation in recommending the company or the mattress.
Incredibly hot to sleep on, sadly have had to return. Having read all the reviews I thought I might have found mattress heaven but sadly not. If you prefer to sleep in a cool bed this is not the mattress for you.

The Casoli mattress is a very good alternative to the normal combo pocket and memory foam mattresses as it will give you all the same comfort without the heat of a foam mattress. This mattress is alo very good for people that have allergies as it contains anti-dustmite properties.
