FAQs

Emma CliMax Hybrid

Is the Emma Hybrid mattress any good?

The Emma CliMax Hybrid mattress is a highly-rated product, specifically designed for those who sleep hot and heavy. It consists of six unique layers that work together to reduce motion transfer, which is beneficial for light sleepers. It also features a cooling technology for enhanced comfort. The mattress is designed to fit every body type and provides point-elastic caving for an ideal fit. However, individual sleep preferences and specific needs should be considered when choosing a mattress.

Is the Emma CliMax a good mattress?

The Emma CliMax is a high-quality mattress and is particularly suitable for heavier back and stomach sleepers as well as larger couples. However, lightweight sleepers and most side sleepers might find a softer mattress more comfortable.

How long will the Emma CliMax mattress last?

The Emma CliMax mattress is expected to last for approximately 10 years, if not longer. Regular rotation of the mattress can help prevent wear and sagging.

Siena Memory Foam

What are Siena mattresses made of?

The Siena Memory Foam Mattress is made with a tri-layer design that includes gel-infused memory foam and two different types of polyfoam. The foam used in the mattress is CertiPUR-US certified, meaning it's free from harmful chemicals and additives.

Can you flip the Siena mattress?

The Siena mattress is not designed to be flipped. It has a high-density base foam layer at the bottom, and flipping it would compromise its pressure-relieving properties.

How long will the Siena mattress last?

The Siena mattress, being a budget mattress, is not made with as many high-quality materials and is therefore expected to last about five years. This is approximately half the lifespan of a typical mattress.
