FAQ’s

1) What is a metal coil box spring?
A metal coil box spring is a supportive mattress foundation built with steel coils that flex slightly to absorb impact and distribute weight. Unlike a rigid “foundation,” a true coil box spring provides shock absorption that can reduce motion transfer and help your mattress wear more evenly over time.

2) Does this box spring actually flex (and is that good)?
Yes—true steel coils compress and rebound to absorb nightly impact. That gentle flex can extend the comfort life of many innerspring mattresses and reduce the “hard board” feel some sleepers notice with rigid platforms.

3) Will the metal box spring squeak?
Ours is designed to be no squeak when properly installed on a compatible bed frame with center support and tightened hardware. If a noise occurs later, it’s usually from the frame or loose bolts—retightening typically resolves it.

4) What height options are available for the coil metal box spring?
Standard height is 8″. A 6″ low profile option is available when you need a lower bed height or are pairing with a thicker mattress.

5) Which sizes do you offer (including splits and custom)?
We build all standard sizes (Twin–Cal King) plus Split Queen, Split King, and custom sizes for antique, European, RV, or unusual frames. If you need a specific dimension, we’ll make it to order.

6) What’s the difference between a coil box spring, a semi-flex, and a rigid foundation?

• Coil box spring: steel coils that flex is best shock absorption.

• Semi-flex: limited flex using a wire grid with some give, less than coils.

• Foundation (platform/rigid): no flex. Best for many foam/latex beds or when the mattress warranty specifies a rigid base.

7) Which mattresses pair best with coil metal box spring?
Innerspring and many hybrid mattresses pair well with a coil box spring. All-foam or latex mattresses often prefer a rigid foundation or slatted platform (per brand warranty). When in doubt, follow your mattress maker’s base requirements.

8) What weight capacity can it handle?
It’s engineered for high, everyday household loads. Because needs vary by size, frame, and center support, ask us for guidance if you have heavy duty requirements and we will onfirm the best configuration.

9) What frame/support do I need under the box spring?
Use a sturdy metal or wood frame with center support on Full and larger (a center rail with a leg to the floor). Slats should be secure and spaced to support the box spring’s ends and center.

10) Do you offer split designs for tight staircases or small doorways?
Yes, Split Queen and Split King are popular for tight spaces. Custom split solutions are available for other sizes on request.

11) How long do custom sizes take?
Most custom builds are ready in 2-4 weeks. If you are moving, we can assist you with delivery days.
