function, consisting primarily of a chair on caster wheels. Caster locks were available on this particular commode, however the plaintiff chose not to purchase them.
On July 5, 1970, while sitting in the commode chair, plaintiff dropped his toothbrush in the lavatory before him. While bending down to pick up the toothbrush, the plaintiff leaned forward in the chair to a point where the back wheels of the commode came off the bathroom floor and the front wheels moved backward. This action caused McIntyre to be thrown forward out of the commode and resulted in the injuries involved herein.
The defendant asserts on appeal that the evidence and verdict of the jury establish as a matter of law that the defendant was not negligent. At the outset an apparent inconsistency exists in the special verdicts submitted to the jury. In its verdicts the jury found in favor of the defendant on the theory of strict liability, finding no defect in the commode chair. However, on the issue of negligence, the jury found in favor of the plaintiffs.
Special answers or findings by the jury must be consistent with each other. If they are irreconcilably inconsistent, they destroy each other. It is, however, the duty of the courts to make every reasonable effort to harmonize the answers.

This case was submitted to the jury under the general rule of strict liability in tort as stated in Restatement (Second) of Torts § 402A. That rule has been adopted in Missouri. Keener v. Dayton Electric Manufacturing Co., 445 S.W.2d 362, 364 (Mo. 1969). It provides:
(1) One who sells any product in a defective condition unreasonably dangerous to the user or consumer or to his property is subject to liability for physical harm thereby caused to the ultimate user or consumer, or to his property, if
(a) the seller is engaged in the business of selling such a product, and
(b) it is expected to and does reach the user or consumer without substantial change in the condition in which it is sold.
The jury herein found that the portable commode chair was not in a defective condition unreasonably dangerous to the consumer. The jury verdict was clearly predicated on the lack of a defective condition in the commode, inasmuch as the other elements to this cause of action, that the defendant was engaged in the business of selling portable commodes, and that the commode reached the consumer without substantial change, were admitted by the defendant.
As to the negligence count, the case was submitted to the jury under four theories: First, that the commode was unstable by reason of negligent design; second, that the defendant failed to perform tests of the commode’s stability characteristics; third, that the defendant failed to warn that the commode would tip; and fourth, that the defendant failed to instruct the user of the risk of tipping if the user leaned forward.
Generally, in order to recover under either negligence or strict liability it is necessary to prove that a defect existed in the product at the time the manufacturer parted with possession. Lindsay v. McDonnell Douglas Aircraft Corp., 460 F.2d 631, 636 (8th Cir. 1972). A verdict in favor of the defendant-manufacturer on the issue of strict liability, finding no defect in the product, would in some jurisdictions preclude recovery under the theory of negligence. In Browder v. Pettigrew, 541 S.W.2d 402, 404 (Tenn.1976), the court stated:
We agree with counsel that in a products liability action in which recover is sought under the theory of negligence, the plaintiff must establish the existence of a defect in the product just as he does in an action where recovery is sought under the strict liability theory or for breach of warranty, either express or implied. The only significant difference is
