The sapphire marquis is a firm (roughly a 7-8 on a 1-10 firmness scale).

A firmer model like this is built for back and stomach sleepers that likely have back or spine issues and need correct spinal and cervical alignment (which is critical for long-term health).

Stay away if you sleep on your side. You won't get the contoured support your pressure points need if you're laying on a flat and even surface with very little 'give'.

The top style does a good job maintaining a flat and even sleep surface to maintain a firmer feel.

The sapphire marquis is inadequate for side sleeping.

Make sure to choose their plushest offering. If you're not sure which model it is, chat or call with them.

Expect acceptable support for delicate pain points (specifically your low back, neck, shoulders, hips). Top foams relieves tension and pressure throughout the body sufficient.

NOTE: If you sleep on your side, make sure you support your shoulders, hips, and torso equally. Otherwise, you'll suffer long-term nerve and pain problems.

The sapphire marquis is fantastic 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 reasonable support for spine and cervical positioning (specifically your lower back). Relatively firm foams on the top layer keep your back straight extremely 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 sapphire marquis 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: euro-top which does a fine job creating a larger sleep surface (good for couples).
• Cover: tencel which is fairly standard.
• Bed in a Box: no information available.
• Weight: unknown weight (queen size).

The sapphire marquis height is 13.5".

• Decent edge support because of its coil base.
• Saatva Classic is an astounding alternative if you want fabulous 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).

Bank on decent movement transfer because it has a coil base.

You or your partner may well perceive a little bit of movement transfer, but odds-on it won't startle you (especially if you or your partner are heavy 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.
