After spending thousands of dollars (literally) on mattresses over the past decade, to accommodate my weight (280+lbs) and to help alleviate my constant daily back pain, my wife came across the Black Sheep Mattress Co's website; We were hesistant at first, but my back just couldn't put up with much more. No matter what mattress we bought, I ended up sleeping in a dip or trough and woke up in pain. We bit the bullet & purchased the Split King Oxford Latex - and I'll tell you, when they say "firm" they really mean FIRM. The bed was actually too firm and we ended up swapping out layers of latex a couple of times before I found my perfect mattress. I have slept on my side of the "split king" for just over 2 months now and I couldn't be happier, my back feels like it did more than 20 years ago. Don't get me wrong, I still have a bad back, but I no longer wake up in back pain and crippled over. My wife says she can actually hear the TV now as my snoring has diminished significantly, and another added bonus seems to be my restless leg syndrome is nowhere near the intensity it was (don't know why a mattress would have any effect on snoring or restless leg syndrome, but I am simply making an observation). The Oxford Latex mattress proved to be too firm for my wife and we ended up swapping out her side of the split king for the Suffolk natural cotton & wool mattress - but I will let her tell her story (spoiler alert - she LOVES it); I have to say I an 100% totally & completely happy with my mattress. Christian and his Dad and the entire staff were awesome. We felt badly that we swapped out layers several times and even totally switched half the mattress to a completely different one, but never once did we feel any pressure or hesitation on the part of Black Sheep. No way in hell are you ever going to get that kind of service and dedication. Thank you Black Sheep Mattress Company.
