Consider Serta Iseries 4000 Plush if...

There's no need to deal with those troubles with the iSeries 4000 Plush! As a result of the combination of memory foam and coil, you can take advantage of the best of both worlds.
• You are a hot sleeper. You can benefit from the iSeries 4000 Plush if you require temperature regulation to sleep comfortably. Sleeping on this bed will be cool and comfortable thanks to the gel infused memory foam, the temperature-regulating cover, and the carbon infused memory foam.
You sleep on your side. With a plush firmness level, the Serta iSeries 4000 is ideal for side sleepers who want cradling comfort combined with adaptive lumbar support.

Avoid the Serta Iseries 4000 Plush if...

• You're a back sleeper. It may not provide you with enough lumbar support if you sleep exclusively on your back due to its plush firmness level.

Firmness, Feel & Comfort for Serta Iseries 4000 Plush

This Serta iSeries Hybrid 4000 has a plush firmness level, ideal for people who sleep on their sides and in combination. It provides pressure relief for shoulders and hips as well as neck pain and neck tightness. With the iSeries Hybrid 4000, you'll feel more "in" your mattress than "on" it, with superior cushioning.

Construction and Design for Serta Iseries 4000 Plush

• With Max Cold Cover, you will feel cool-to-the-touch thanks to temperature-regulating, high-performance fibers.
• The UltraCold System channels excess heat away to keep the mattress comfortable and cool.
• Carbon Fiber Memory Foam layer disperses excess body heat while providing optimal lumbar support.
• By increasing airflow and dissipating heat, EverCool Fuze Gel Foam further contributes to temperature control.
• In the 1025 Hybrid Support System with Best Edge Foam coil system, individually wrapped coils provide targeted support and adjust to your body's movements as you sleep. Encased in Best Edge foam to reduce roll-off and maximize usable surface area.

Support & Motion Isolation for Serta Iseries 4000 Plush

This mattress's 1025 individually wrapped coils combined with quality layers of body conforming memory foam make the Serta iSeries 4000 Plush great at providing motion isolation. The coil system provides targeted support and reduces motion transfer across the bed, while memory foam layers absorb impact from sudden movements, allowing you to sleep undisturbed. it's a great choice for couples!

Like this bed's motion isolation performance, the Serta iSeries 4000 Plush performs exceptionally at edge support. The border of this mattress is encased in an extra deep high density foam rail which reinforces its edges. This means that more surface area can be used, and potential roll-off and sagging are greatly reduced.

Reason(s) To Buy Serta Iseries 4000 Plush

There aren't any notable reasons to buy a mattress from Serta.You're likely much better off considerating popular (but established) brands like Saatva or Puffy. Both brands are built in America, have incredibly positve reviews, and are genuinely comfortable (+ built to last).

Reason(s) To Avoid Serta Iseries 4000 Plush

1. You want an eco-friendly option. This Serta mattress is CertiPUR-US certified, meaning it's made with safe, high-quality materials. This certification doesn't mean it's eco-friendly though! Look for a natural latex product with a GreenGuard certification if you want to make an environmentally conscious purchase.

The Verdict
