Hi there, please could youbrevommend a king size mattress for my husband and I? We are both side sleepers between 12-13 stone. I'm 5ft 6 and he us 5ft 10. I am currently pregnant so experiencing alot of aches and pains, particularly lumber/hip region and we are both waking with numb arms on a regular basis. My husband also suffers with a bad neck. Our last 2 mattresses have been memory foam, the latest being a 2 year old Eve mattress but I just don't feel it giving us the support we need as we are both in alot of discomfort when we wake. Please help! Thank you.
