Bought for my son who is rather heavy! So we needed a quality, durable mattress. Looks like we've got one. Impressed with mattress-online - very competitive with no diminished service as a quid pro quo.

The firmness and sleep quality is amazing. We also like the fact that the mattress can be rotated and turned over which will give even wear over its lifetime.

Sleeping great, it does that mix of comfort and back support really well, had a Hypnos before, and this is new one even better. Highly recommended if you need a quality mattress that's a bit firmer.
