Quick answer
What should you know about TEMPUR-Flat® Foundation?
TEMPUR-Flat® Foundation is intended to provide a stable support surface for a compatible mattress. Before ordering, confirm the mattress size, the foundation height offered, and the mattress manufacturer’s support requirements. A foundation is not the same as an adjustable base: a standard foundation remains flat, while an adjustable base changes position. Also confirm whether your bed frame requires center support, especially for Queen, King, and California King sizes. Delivery and setup method can vary by model and destination, so use the product details and checkout information for the current order.

Questions shoppers ask about TEMPUR-Flat® Foundation
Is TEMPUR-Flat® Foundation compatible with my mattress?
Match the foundation and mattress sizes, then check the mattress manufacturer’s support and warranty requirements. Some mattresses require specific slat spacing, center support, or an approved foundation.
Is a foundation the same as an adjustable base?
No. A standard foundation creates a flat support surface. An adjustable base uses powered sections to change the head or foot position and requires a compatible mattress.
Which foundation height should I choose?
Choose a height that creates a comfortable total bed height after adding the mattress. Review the variants above and measure your frame, foundation, and mattress together.
Can I see TEMPUR-Flat® Foundation in a Texan Mattress showroom?
Showroom availability varies, and some accessories are online assortment items. Contact Texan Mattress before visiting if you want to confirm that this exact model is available to see.
How is TEMPUR-Flat® Foundation delivered?
Delivery and setup depend on the model, size, and destination. Review the current product details and checkout information, or contact Texan Mattress for order-specific guidance.
