The X12 is a Sleep Number model that uses technology (via their Sleep IQ app) to help you score sleep (with tips on how to improve it).
The mattress is as comfortable as you'd expect for an $8k mattress. Definitely does not justify the extreme price.
Extremely expensive ($8k+) and recommendations from their technology are basic (and something you can find with dedicated apps on Apple or Android).
There are no online reviews, which is typically a red flag.
The sleep number x12 has several firmnesses to pick from depending on which model you select.
If you're a side sleeper, pick any firmness except firm and very firm. Isn't firm enough to create support and contouring issues (for most people).
If you're a back and/or stomach sleeper, choose a (a) medium firm (5-6), (b) firm (7-8), or (c) very firm (8-9) comfort level. It's important to maintain correct spine alignment when you sleep. Otherwise you'll wake up with serious pain and long-term back/cervical issues.
The sleep number x12 is bearable for side sleeping.
Make sure to pick their plushest offering. If you're not sure which model it is, chat or call with them.
Anticipate acceptable support for delicate pain points (specifically your low back, neck, shoulders, hips). Top foams relieves tension and pressure throughout the body sufficient.
NOTE: When you sleep on your side, make sure your shoulders, hips, and torso are all equally supported. Constant pressure causes long-term nerve and pain problems.
The sleep number x12 is solid for back and stomach sleeping.
Ensure to select their luxury firm (6.5/10), firm (7/10) or very firm (8/10) option. If you're not sure which model it is, reach out to them.
Bank on tolerable support for spine and cervical positioning (specifically your lower back). Relatively firm foams on the top layer keep your back straight reasonably well.
NOTE: Focus on finding a mattress that won't sink too far into your hips when sleeping on your back & stomach. It'll throw your spine out of alignment.
The sleep number x12 has several layers worth exploring:
• Bottom Layer: foam for sturdy support.
• Transition Layer: foam for padded pressure relief.
• Top Layer: foam for additional comfort & overall support along the top layer.
• Top Design: tight-top which does a fine job creating a larger sleep surface (good for couples).
• Cover: polypropylene fabric which is fairly standard.
• Bed in a Box: no information available.
• Weight: unknown weight (queen size).
The sleep number x12 height is unknown height.
• Unexceptional edge support because of its memory foam design.
• Loom and Leaf is an outstanding alternative if you want staggeringly good edge support.
Note: If a mattress uses low-quality materials, it might feel supportive at first, but break down FAST.
Inadequate edge support means less sleep surface (which is not desirable, especially if you sleep with a partner).
Expect exceptional motion transfer as a result of the memory foam design.
You and your partner won't sense a single bit of motion transfer, and definitely won't disturb you (whether you or your partner are heavy sleepers or not).
NOTE: Motion transfer signifies how much movement shifts from one side bed side to another. If you or your partners shifts a lot at night, you must buy a mattress that has great motion isolation.
Less motion transfer = deeper sleep = happier life.
