This bench is designed with a gap in the chest rest of the bench making it more comfortable for women. This is great for adding nipple clamps or weights. This is also idea for women who simply don't like to lay on their breast. It has a built-in massage table face cradle for added comfort. This means you can stay on the bench for longer periods of time without getting neck crimps. It is made of 2 x 4 pine wood. All joints are either bolted or screwed together. No nails are used in this. The chest rest is 16" wide by 27" long. It is mounted with a 15-degree angle. The face cradle at the front of the bench has 2" thick foam on the inside, covered with a soft yet durable vinyl. The cushion at the back end of the chest rest is 16" wide and 11 1/2" long, with 2" thick foam padding. The padding is covered with a durable black vinyl. (Leather is available upon request.) The arm rest are made of 2 x 4s x 14" long. They too or padded with two-inch-thick foam. The two-knee rest are 6" wide, and 19" long and stands about 14 1/2"" from the floor. They are also cushioned with 2" thick foam and covered with black vinyl. The knee rest has been reengineered for greater stability. They can be mounted parallel to each other, or with a 10-degree angle causing the legs to be spread apart. This allows plenty of room for a person to stand between the legs. The rear knee extensions can easily be removed for storage by unscrewing the two mounting nuts. The heavy-duty construction of this bench is guaranteed to last a lifetime, and will hold up to 400 lbs. If you like this bench, but prefer to have it built without the angle, no problem. When you place your order, simply write in the comment section "please build my bench without the angle". Upon checkout, you will have the option to add a set of heavy-duty leather hand and ankle cuffs. The bench already comes with eye bolts in just the right places for attaching hand and ankle cuffs. You will also have the option to add a vibrator to the rear of the bench, to add additional stimulation.
