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.

Bank on adequate support for spine and cervical positioning (specifically your lower back). Firmer top foam layer keep your back straight mediocrely.

The sleep to live series 400 has several layers worth exploring:

• Bottom Layer: pocketed coils 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: there is no cover information available which is fairly standard.
• Bed in a Box: no information available.
• Weight: unknown weight (queen size).

The sleep to live series 400 height is 14.75".

• Passable edge support because of its pocket coil construction.
• Saatva Classic is an impressive alternative if you want stellar 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).

Count on passable motion transference due to its pocket coil construction.

You and your partner might possibly experience a small amount of motion transference, but odds-on it won't wake you (especially if you or your partner easily wake at night).

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.
