  • King

    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).

    Cool conforming comfort is what you get with the Dream Bed Lux LX670 plush mattress, available now in store and online from Mattress Firm. Try it out today to see if it’s the right mattress for you with our 120-night sleep trial.

    At 14” thick there’s a lot of soft comfort built into this mattress, starting with the durable Ecocell™ HD base. Next comes the 3” Octaspring® Support System, using a honeycomb shape to allow airflow even as it provides lasting support. The 1” Dream Cool Infuse™ HD and 4” Dream Cool Sense™ Soft HD memory foam layers provide the conforming comfort without the overheating, through the use of phase-changing materials that move heat away from the body rather than trapping it there. To top it all off, the Dream Cool Activ™ Technology cover, enhanced with air mesh for better breathability.

    Designed with back and side sleepers in mind, the Dream Bed Lux LX670 keeps the pressure away from your shoulders, hips, and back. The LX670 is suitable for use with an adjustable base for further back pain prevention.

    Get better sleep and dream cool with the Dream Bed Lux LX670.

    LX670 14" Plush Memory Foam Mattress is rated 4.3 out of 5 by 33.
    Rated 5 out of 5 by from enjoying sleep Our previous bed was well past the expiration date, we were not sleeping at all and would wake up with sore shoulders and back. Anything would have been an upgrade. We originally ordered a tempurpedic but they never shipped our bed. Now we wanted something ASAP and decided to just go to a local mattress firm and test out some beds... They were having a sale on the bed, 20% off and save the tax. We decided to give the dream lux 670 a try and picked it up at their warehouse (I'm telling you, we couldn't even wait for shipping our mattress was so bad! LOL). We have had the mattress for 3 nights now, i really love it! Its supposed to soften up over the next month and I'm looking forward to that BUT it is sleeping well already. Im usually a side sleeper but its still a little too firm to sleep all night on my side. My husband hasn't decided if he is 100% sold on it but i know he is sleeping better because he isn't tossing and turning into me all night. I would highly recommend this bed. I will update over the next few months if it gets better or worse.

    Rated 5 out of 5 by from So much better than Tempurpedic! I had a Tempurpedic for years and loved it, however, after years of sleeping on it, we started waking up really stiff and sore. I was going to buy another Tempurpedic, but when I payed down on this, I was sold. I’ve had this now for about 8 months and still look forward to going to bed every night. LOVE this mattress

    Rated 1 out of 5 by from Not Plush We bought this mattress about 10 days ago and are miserable....agreed with one of the other posts, it felt completely different in the store. This is just way too firm and we wake up with aches and pains in our backs and shoulders in the AM. We really wanted to like it, but just can't spend the time waiting for it to soften up.

    Rated 2 out of 5 by from Not a plush mattresses Purxhesed this mattress based on it being a plush. It’s at best a medium or closer to firm. Stay away if you are a side sleeper. Woke up with shoulder pain and lower back pain for 30 nights. I am going to try the 710 next.

  • Warranty Info

    10 Year Limited Warranty

    This supplier provides a ten (10) year limited Warranty for its DREAMBED LUX mattresses (“Limited Warranty”). Please review the Limited Warranty and keep it in a safe place. Please be sure to retain YOUR ORIGINAL SALES RECEIPT (or a readable photocopy) for proof of purchase date as well as ALL TAGS (law tag) that are sewn into your mattress. We recommend leaving any tags intact on your mattress. In the event, you are required to return your product or submit a warranty claim, these documents will be required. Please keep them on file in a safe and secure place for future reference. We stand behind our Limited Warranty, so please contact us immediately with any issues you may experience so that we can resolve it as soon as possible for you.

    In our sole discretion and option during the Limited Warranty, we will repair or replace the original purchaser’s DREAMBED LUX mattress if it is defective due to faulty workmanship or materials, subject to the limitations described in this warranty. This warranty is applicable only to the original purchaser of the DREAMBED LUX. Warranty does not apply to floor models or “Demos”.

    This supplier shall not be liable for incidental or consequential damages resulting from the use of this product or arising out of any breach of this warranty. The foregoing warranty is exclusive and no other warranties, express or implied, including implies warranties of merchantability and fitness for a particular purpose, are made hereunder other than the warranty described herein.

    DREAMBED LUX mattresses are designed for full performance when used with a supportive foundations system (platform bed, slatted frame with horizontal center supports, a box spring and or adjustable bed). If used on a faulty foundation system or on the floor or any other equipment not specified, resulting in damage to the mattress or your personal property, you Limited Warranty will be void. Proof of the quality of the foundation, adjustable bed base, or bed frame used in conjunction with the mattress will be required if purchaser makes a claim under this Limited Warranty. The supplier reserves the right to invalidate this Limited Warranty if the foundation is determined, in the suppliers reasonable discretion, to be inadequate.

    The Limited Warranty Does Not Apply To: imperfections of the fabric; slight body impressions (less than ¾ inch in depth). However, if body impression found in a DREAMBED LUX mattress is 3/4 of an inch or more in depth and IS NOT associated with use of an improper or unsupportive foundation (or other misuse), it may be covered by the warranty.; comfort or temperature preference; transportation charges (if applicable); any abuse or unsanitary product conditions; or damage caused by improper use or care. Limited Warranty does not include a normal increase in softness of the memory foam material or a decrease in the slow recovery feature (elasticity). These aspects do not affect the pressure-relieving qualities of the foam.

    The Warranty is Deemed Null and Void If/When: if the product is found to have been tampered with or misused beyond reasonable wear, and shall not apply if the product has been physically damaged intentionally or due to accident or neglect, including but not limited to, damage by burns, cuts, water, stains, bodily fluids or is otherwise abnormally soiled or unsanitary. It is recommended that the consumer protect the mattress with a stain resistant mattress pad or mattress cover. This Limited Warranty does not cover defects or damage caused by a consumer’s failure to follow these recommendations; there is improper or unsupportive foundation used; there are insect infestations; the mattress has not been properly packaged resulting in damage during return shipping; the original purchaser cannot provide an original proof of purchase receipt and law tag.

    Additional Information: If the original mattress model is not available at the time of repair or replacement, the supplier reserves the right to offer an alternative model of equal quality or value, in its sole discretion. Mattress dimensions (length and width) have a ±2% tolerance due to elastic components. This tolerance is considered normal and does not constitute a defective mattress and is not subject to a warranty claim, whether after short- or long-term use of the mattress. In the event of an authorized product repair or replacement, the Warranty Period will not be renewed or extended following the repair or replacement. In short, a repaired or replaced mattress does not reset or in any way alter the Warranty Period duration in connection to subsequent warranty claims, if any.

    Mattress Cover Limited Warranty The mattress cover provided with the mattress is warranted for one (1) year from the original date of purchase to be free of defects in the material or workmanship. The supplier will replace or repair a cover at its option within the one year period at no cost to the original purchaser, excluding return shipping costs.

    Shipping and Handling Fees The original purchaser is responsible for all one-way shipping and handling fees when returning the mattress or removable mattress cover for all warranty claims.

    The repair or replacement as provided under this Limited Warranty is the exclusive remedy of the consumer and is provided in lieu of all other warranties, express or implied. In no event shall the supplier. Be liable, whether in contract or tort (including negligence), for damages in excess of the purchase price of the product, o for any direct, Incidental, special or consequential damages of any kind or loss to the full extent that these damages may be disclaimed by law. Some states do not allow the limitation or exclusion of incidental or consequential damages, or limitation on the length of an implied warranty, and so the above limitations or exclusions may not apply to you. This limited warranty gives you specific legal rights that vary from state to state, and you may have other rights which may vary from state to state.
