Sleepy's Universal Box Spring
- Available in 5” and 9” heights
- Durable and noiseless
- Strong steel foundation
When it comes to mattresses, one size definitely doesn’t fit all. The mattress should be longer than the tallest person sleeping on it. The bed width should allow enough space to fold your arms behind your head without going beyond the mattress edge or touching your partner’s elbows (for two adults, we recommend either a queen or a king).
- Split sizes also available. Contact us!

Mattresses aren’t the only important part of your bed; you also need the right foundation. The Universal Box Spring is a strong steel foundation for a quiet night’s sleep. The steel construction is quieter and stronger than all-wood alternatives, making it the perfect choice for your new bed. Available in two height options; five inch low-profile and nine inch high-profile, the Semi Flex will also give you a great foundation for your bed. The design has tailored corners and a neutral color that add to the visual appeal of the unit. It passes all durability tests; including Cornell, Rollator, and Impact, making it a lasting staple in your bedroom for years to come.

10 Year Warranty
Mattress Firm warrants your Mattress, for a period of ten (10) years — full warranty — against defects in workmanship and materials. During the ten (10) years, if the product is deemed to be defective, the product will be repaired or replaced as stated below. All transportation costs are the responsibility of the purchaser during the entire warranty period. Your mattress will be replaced or repaired, at our option, should it be found defective because of faulty workmanship or structural defects other than specific limitations contained herein. It is understood that this does not include normal increase of softness in the foam which can occur during normal breaking in, or in the case of visco-elastic memory foam, a lessening of the gradual recovery aspect of the foam, of which such lessening, should it occur, does not reduce the continual pressure reducing and pressure relief properties of the mattress. Substitution or use of improper foundations, platforms or other bases upon which the mattress is placed, may result in damage to the product. Should an improper base be utilized by the consumer, causing the product to default, the warranty may be voided. It is incumbent on the consumer to maintain the foundation and provide appropriate support for the mattress. We recommend the purchase of a foundation at the time of mattress purchase. Warranty does not include any deterioration of the foam, with an indentation of less than .75 inches, not associated with a sag in the foundation, box spring , platform or frame. If such a defect appears during the ten (10) years of this warranty, we will, at our option, either repair or replace the mattress at a handling cost to be paid by the purchaser. This warranty does not include handles, as handles are to be used only for adjustment purposes and are not intended to be used to lift, turn or transport the product. If a model has been discontinued we will replace it with a mattress of equal or greater value at our option. The zippered cover on the mattress is warranted for two (2) years for defects in material or workmanship. This warranty is void if the product is found to have been tampered with or misused by the purchaser beyond reasonable wear, and shall not apply if the product has been physically damaged intentionally or due to accident and/or neglect; including burns, cuts, water damage, mold, stains, or is otherwise abnormally soiled or unsanitary. Do not use a heating pad or electric blanket with this mattress as it will void this warranty. It is recommended that the consumer protects the mattress with a stain resistant mattress protector. This warranty is valid only to the original purchaser of the product as indicated on the original sales invoice. Law tag must not be removed from original product as this identifies the product and the original invoice is required and is the only acceptable proof of purchase. This warranty gives you specific legal rights and you may also have other rights that vary from state to state. In order to provide the optimum sleeping surface this premium product contains only the finest quality materials. As with all premium sleep products certain body conformity adaptations will take place as your mattress adapts to your particular body shape and type and any peculiarities in your spinal alignment or bone structure. This is to be expected and is part of the performance of your mattress. Our representative or designated agent shall make the final determination regarding repair or replacement. We do not warrant our product as a remedy for any specific medical condition and do not warrant against any complications resulting from the use or inability to use this product. We do not warrant individual comfort preferences, sheet fit or height issues resulting from purchaser’s bed frame size or headboard style. Should this warranty be exercised and your product replaced and/or repaired, the duration of the warranty will not be extended or restarted. Terms and service related in this warranty shall be the consumers sole and exclusive remedy should the product fail during the time frame stated here in. We make no warrant beyond those terms and conditions stated.
Please retain this warranty and your original invoice for ten (10) years.
