User 1: "I just got my i8 on Tuesday and am absolutely miserable. It’s a complete gimmick. It is 100% an air mattress with a fancy pump. Every night worse than the last. I went to bed at 9pm last night and didn’t fall asleep until 3am. Now I lay here and my whole body is in pain."

The sleep number i8 is a medium comfort level (about a 5-6 on a 1-10 firmness scale).

Ideal for all sleep positions, including back, stomach and side sleepers. You'll have a balance of cushioning firmness for back/stomach sleepers and contouring support if you're a primary side sleeper.

The top style does a good job maintaining a flat and relatively even sleep surface, too.

The sleep number i8 is adequate for side sleepers.

Make sure to choose 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: Make sure you have equally supported shoulders, hips, and torso if you sleep on your side. Otherwise, concentrated pressure can harm your nerves.

The sleep number i8 is okay 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 passable support for spinal 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.

The sleep number i8 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: knit fabric which is fairly standard.
• Bed in a Box: no information available.
• Weight: 63 lbs (queen size).

The sleep number i8 height is 12''.

• Satisfactory edge support because of its foam substructure.
• Loom and Leaf is a shatteringly good alternative if you want marvelous 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 outstanding movement transfer because of its foam substructure.

You and your partner won't notice a single bit of movement transfer, and emphatically won't stir you (whether you or your partner are heavy sleepers or not).

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.
