Don't get a sleep number bed!

We bought the split top king iLE with adjustable base for 8K. It was delivered (team spoke little English & made my home smell of smoke & BO). They could not get the base to work. I could not understand the delivery guys, he handed me a phone with a manager who explained they would unplug the power to the base, but mattress would work. They would replace it. Another day off of work for another delivery. I could understand the 2nd team, and they were professional. However, they were confused - seems no one communicated to them they were swapping out a base. I had to catch them up. They had to make some calls to figure out what was what, then assembled our bed, got it to work. As we slept a few weeks on the split top, we realized the gap was pulling wider and wider and there was a big space down the middle of the bed and our dogs would fall through - we called to swap out the bed for the full king (no split at top). This voids the 100 day trial when the new bed arrives. So another day off of work for the new mattress to get here - the team is another bad experience - smell of smoke & BO; cannot speak any English. They put the bed together and leave. I notice later when putting on sheets the cover that zips on the sleep number bed is ripped in 2 places - it wasn't sewn together at the factory - we take pictures and call our sales guy. We really can't take a 4th day off of work to deal with this bed. So, we agree to have them ship to us a new zip on cover - they say we can watch youtube videos on how to install it. Personally, I think they should make a weekend available to come take care of this as we paid 8K! cover arrives and I go to put it on - wrong size was sent - it made a big gap at end of zipper about 3 or 4 inches. i think it's a CA King. I'm done - ship back this cover and put on my ripped one and i'll sew it up myself. Enough time spent on this bed and days off. Advice - don't buy a sleep number bed - lots of headache. I miss my tempurpedic - it was better quality. Wish I could return this but i'm stuck
