My wife and I bought a Sleep Number about 4 years ago. It was one of the mid-range models that had recently been discontinued, so we got a discount on it. I asked the associate what the more expensive models had and she explained “more padding”. I found that extra padding to be uncomfortable, and the model we bought works great.
The worst part of a Sleep Number is the cheap modular plastic platform that they sell. Instead of buying this I built my own platform-style bed frame, which cost the same, except it’s far sturdier and looks much better. I can describe how to make one if you’re interested.
Sleep Number tried to make us pay a delivery fee since they “don’t allow” pickup. I negotiated for free delivery. We also negotiated for a free extra remote.
Sleep Number markets (or used to market) the “Sleep IQ” to track sleep patterns, etc. The same exact features can be downloaded for free as a cellphone app.
One disadvantage of Sleep Number is if the batteries in both remotes die, it will slowly deflate. Just check the batteries every 6 months or so.
Sleep Number is expensive compared to other brands, but if you shop wisely for a model that meets your needs, look for sales or discontinued models, and skip questionable add-on features, you can still get bang for your buck (we did). I think we paid about $3200 all together for mattress, platform/frame, bed set, 4 pillows, and skirt.
On any new mattress it can take up to 6 weeks for your spine to adjust to the surface. I’d suggest finding an initial inflation number that you like, and then stick it out for 6 weeks before tweaking it again.
Lastly, don’t skimp on pillows. My wife and I each have a nice body pillow and premium king-size feather pillows. About half your sleep comfort comes from your pillow.
