Key Takeaways


Sleep Number S1 is a tight-top mattress with a 5-zoned support comfort layer that comes with a 15-year limited warranty.

Decent height (indicates a sturdy mattress). Its tight-top design is great for a flat, even sleeping surface.

Cover style might be too firm for some. Avoid this unremarkable mattress. Far much better options are available.

Loom and Leaf is the #1 alternative you can buy. Their 5 lb. memory foam density is extremely high quality and built to last. Euro-pillow top and soft organic cotton cover contours to your sensitive pressure points and provides tremendous overall support. Their customer service is excellent (probably the best of all brands) and their policies are generous.

  • Decent height (indicates a sturdy mattress)
  • No motion transfer


  • Much better value-oriented alternatives.

Real Reviews For Sleep Number S1

There are no online reviews, which is typically a red flag.

Comfort, Feel & Firmness For Sleep Number S1

The sleep number s1 has several firmnesses.

If you're a side sleeper, pick the softer firmness. Otherwise the mattress isn't firm enough (which then creates support and contouring issues).

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.

Side Sleeping On Sleep Number S1

The sleep number s1 is adequate for side sleepers.

Make sure to pick their most plush option. If you're not sure which model it is, call or chat with them.

Expect tolerable support for sensitive pressure points (specifically your neck, shoulders, low back, hips). Foam on top relieves tension and pressure throughout the body fine.

Note: If you sleep on your side, make sure your shoulders, hips, and torso are all equally supported. Otherwise, concentrated pressure causes long-term nerve and pain problems.

Back & Stomach Sleeping On Sleep Number S1

The sleep number s1 is good for back and stomach sleepers.

Ensure to select their luxury firm (6.5/10), firm (7/10) or very firm (8/10) offering. If you're not sure which model it is, contact them.

Anticipate sufficient support for spine and cervical alignment (specifically your low back). Relatively firm foams on the top layer keep your back straight surprisingly 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.

Construction & Design For Sleep Number S1

The sleep number s1 has several layers worth exploring:

• Bottom Layer: foam for sturdy support.
• Transition Layer: foam for padded pressure relief.
• Top Layer: gel 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: no cover information available which is fairly standard.
• Bed in a Box: bed-in-a-box.
• Weight: unknown weight (queen size).

Height For Sleep Number S1

The sleep number s1 height is 10".

Edge Support For Sleep Number S1

• Unremarkable edge support because of its memory foam support.
Loom and Leaf is a fantastic alternative if you want splendidly 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).

Motion Isolation For Sleep Number S1

Anticipate excellent motion transference as a consequence of the memory foam support.

You or your partner won't detect any motion transference, and categorically won't startle you (even if you and your partner are light sleepers).

NOTE: Motion transfer is how much movement transfers from one side of the bed to another. Sleep on a mattress that offers effective motion isolation if your partner tosses and turns.

A better night's sleep leads to a happier life.
