Horrid! Do not purchase

We originally purchased this mattress 3 years ago. Within 2 months we had a warranty claim and for sagging in the middle. So we get the next one and it lasted about 18 months or so. Filed another claim. Got a 3 mattress delivered for $85, and it has lasted 6 weeks. This one is worse than the others. 3inch depression in the center. Turned in another claim and said under no circumstances do we want this piece of #@@%, again. Waiting to here from Simmons. Worst purchase ever. But I will say the warranty claim has been processed quickly. Only good thing.
