User 1: "This mattress started sagging in the first month. It is horrible. Spent so much on it, now I can't afford another. My husband sleeps on the couch most nights. Would love to get my money back. Do not buy this!"

User 2: "Terrible mattress. This mattress provides no support whatsoever. I have had this mattress for less then 10 months. I have never experienced a mattress that after sleeping on it for a few months, a large hole in the middle was created. This bed has caused me to have lower back problems. In an effort to bridge the sagging area, l have had to lay two pillows side ways in the hole to build it back up and then lay a foam cover over the entire bed before putting on the fitted sheet. I will be getting rid of this bed very soon."

The serta perfect sleeper glenmoor 3.0 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 Serta Perfect Sleeper Glenmoor 3.0 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 Serta Perfect Sleeper Glenmoor 3.0 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 Serta Perfect Sleeper Glenmoor 3.0 has several layers worth exploring:

• Bottom Layer: pocketed coils 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: pillow-top which does a fine job creating a larger sleep surface (good for couples).
• Cover: cooling fabric which is fairly standard.
• Bed in a Box: no information available.
• Weight: unknown weight (queen size).

The serta perfect sleeper glenmoor 3.0 height is 14".

• Suitable edge support because of its pocket coil style.
• Saatva Classic is a phenomenal alternative if you want awesome 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 suitable motion transference as a result of the pocket coil style.

You or your partner may possibly experience a fair amount of motion transference, but likely won't awake you (especially if you or your partner are heavy sleepers).

NOTE: Motion transfer measures how much movement shifts from one side bed side to another. If you sleep with a partner who tosses and turns during the night, get a mattress that offers effective motion isolation.

Less motion transfer = deeper sleep = happier life.
