This is a review of the Select Comfort Sleep Number 5000 bed. I love this bed. It cost about $2500 and is worth every penny. My husband and I both like a different hardness of mattress and this bed allows it. This way we both get a better nights sleep and don't wake up with sore backs from being uncomfortable. I also like the way you can change the hardness of the mattress whenever you like. It is very easy to do, you just lay in the bed and hold the remote and adjust the mattress hardness either up or down in increments of 5. The pump makes the adjustments very quickly and it is fairly quiet. This bed comes with a 20 year warranty and because of the air, the bed does last a long time so it makes it a very good value for the money. It ends up costing you less than buying an expensive traditional mattress because you will have this one for more years before it wears out. This is a great mattress and I highly recommend it.
