We used Stable Comfort, which you can look up at
http://www.stablecomfort.com. The initial cost is high, but the savings in bedding, cleaning ease, and comfort for the horses was worth the initial expense to us.
Here is the testimonial I sent to them today: "I am extremely pleased with the Stable Comfort floors I installed in our little family stable. Let me tell you why.
We were boarding our 19 year old Hackney pony mare and 9 year old Peruvian horse gelding at a stable that had hard rubber stall mats over a dirt floor. No matter how much bedding we put down, the mare was often stiff and sore, and the gelding had sores on his hocks. The mats shifted and were hard to clean. In addition, the smell of urine was tough to overcome. When we bought a house and built our own little 5-stall stable, we wanted something better for our equine friends. After speaking with several veterinarians and researching on the internet, we decided to install the Stable Comfort stall floors. That decision turned out to be more critical than we could have known.
I installed the floors in all five stalls by myself in a matter of days. We used well-compacted road base mix for a subfloor. All of our horses (we now have four) love their stalls, and spend time lying down in them every night. The Hackney pony mare, now 20, is as spry as a 6 year old; the Peruvian horse’s hock sores are a thing of the past. Our third horse, an Appaloosa gelding that had never been stabled before, adjusted to his stall without any issues. The stalls are very easy to clean and disinfect, and use of excess bedding has plummeted.
A few months ago, my 10 year old daughter earned $100 in one month to purchase a 4 month old Mustang/Appaloosa foal that was starving. Due to his early malnutrition, Wind Dancer’s joints did not form properly, and he ended up tearing the cartilage in his right front fetlock at 8 months of age. Surgery by an equine joint specialist was required to save the foal. In the days leading up to the surgery, he spent nearly all the time lying down in his stall, and I was very thankful for the soft floor he had to rest on. During surgery, a cartilage flap that had torn had to be removed, and he was left with bare bone--no cartilage--on the major weight-bearing part of the fetlock joint. The surgeon stated that it was the most significant damage he had ever operated on; prognosis for recovery was very grim. Following surgery, he has been confined to his stall for 30 days; we are now at the 12 day point in this stall rest period. With the cushioning of the Stable Comfort floor, his recovery has been nothing short of phenomenal, as assessed by our veterinarian yesterday as she removed his sutures. He walks and trots with only a minor limp, and does not seem to be at the level of pain one would expect from such massive damage. As his stall rest continues, I am so thankful that he has a safe, soft, cushioned place to recuperate.
I am thoroughly impressed with Stable Comfort, and recommend this stall floor to anyone who has horses, especially rescues and horses recovering from injury or surgery to the legs."
