Specifications and FAQs

The practical details.

What sizes are available?

Twin, Twin XL, Full, Queen, King and California King are available when the corresponding Shopify configuration is orderable. Dimensions update beside the size selector.

What base can I use?

Use a rigid, supportive foundation with minimal spacing between slats. A traditional box spring is not required unless it is designed for modern hybrid mattresses.

What does the GlacioTex pillow top change?

It adds a cool-to-the-touch cover and an additional pillow-top layer. It does not turn the mattress into a different model or firmness category.

How does ErgoAlign differ from Standard Support?

ErgoAlign adds targeted reinforcement through the hip and lumbar area. Standard Support retains the model’s normal comfort and pocketed coil construction.

Does ErgoAlign guarantee relief from back pain?

No mattress can guarantee a specific medical outcome. Comfort and support preferences vary, and customers with medical concerns should consult an appropriate professional.

How should I care for the mattress?

Use a breathable mattress protector, keep liquids away from the surface and rotate the mattress periodically. Do not fold or sharply bend the expanded mattress.
