What is the benefit of a high-profile mattress foundation?
A high-profile foundation, like this 9-inch model, is the traditional choice for those looking to add significant height to their sleep set. This is particularly beneficial if you prefer a taller bed that is easier to get in and out of, or if you want to achieve a classic, commanding aesthetic in your bedroom. Additionally, the extra height can provide a more comfortable seating level when you're dressing or relaxing on the edge of the bed.
Can I use this foundation with a memory foam or hybrid mattress?
Yes, this foundation is an ideal partner for memory foam and hybrid mattresses. Based on our expertise, these heavier, more flexible mattress types require a completely flat and rigid support system to perform as designed. The reinforced slat construction of this model provides the necessary "no-flex" support that protects the mattress core and ensures your warranty requirements for a proper support system are met.
How does the slat design of this foundation improve mattress support?
To provide a sturdier and more reliable base, the wooden slats in this foundation are cut a full inch wider than the industry standard and placed closer together. This dense slat configuration creates a more uniform support surface, which is critical for preventing the sagging or "sinking" that can occur with modern mattresses. By minimizing the gaps between slats, the foundation helps extend the lifespan of your mattress and ensures consistent comfort across the entire surface.
Why is kiln-dried Canadian Spruce used in this foundation's construction?
The use of sustainably sourced Canadian Spruce ensures exceptional durability and strength. By kiln-drying and heat-treating the lumber, we remove excess moisture that can lead to warping, splitting, or squeaking over time. This advanced preparation process results in a stable, high-performance frame that maintains its structural integrity much longer than standard untreated wood bases.
Is a Twin XL foundation suitable for a college dorm or a small apartment?
Absolutely. The Twin XL size (80"L x 39"W) is the standard for most college dormitories and is an excellent choice for studio apartments or guest rooms where space is at a premium. Because this foundation is meticulously hand-assembled with durable spruce and features an upholstered finish, it is built to withstand the rigors of frequent moves and the high-traffic lifestyle of a student or urban dweller.
How should I maintain and clean an upholstered mattress foundation?
Based on our furniture care guidelines, we recommend regular vacuuming with an upholstery attachment to remove dust and allergens from the fabric surface. For minor spills or spots on the solid black upholstery, you should blot the area immediately with a clean, soft cloth and a solution of mild soap and warm water. Avoid using harsh chemicals or saturating the fabric, as this can damage the upholstery and the structural wood underneath.

This is my second tempur topper, highly recommend

Years ago I bought the tempur topper and loved it. Changed mattress sizes and tried to go with a cheaper version from an online retailer, that was a waste of time and money. Nothing compares to the tempur topper. It’s soft and cooling and easy to wash the removable cover.

Pain in the neck…
This review was collected as part of a promotion
When you first lay your head dow, it feels like you’ve laid on a rock. Slowly and immediately your head starts to sink until you’re now an inch from your mattress with 2 rocks on the side of your head. Purchased this on black friday and tried it for a month and it caused me so much head, neck, shoulder pain that I was in tears. Finally gave up on it and gave it to my husband who hates it equally as much. The description for this pillow was med- firm. It’s NOT firm or supportive. The cooling feature is nice, which is why it earned a star. We have 2 Tempur-pedic pillows from when we purchased our mattress 10 years ago. They’re wonderful and firm and we wanted two new ones and they do not make them like this anymore.

Run, don’t walk to buy one of these!`
We bought two twinXL’s that sync together with our new king mattress (other brand). The mattress is unbelievably comfortable, but my wife and I both agree the biggest improvement to our new sleep system was these bases. We love the adjustment, we have it setup for watching TV for an hour before bed, and then press a button and go to your custom sleep position 9feet and head slightly raised). We all spend a quarter of our lives in bed, why not spend a little extra and make it worth your while! It actually adjusts if you snore, gives you a daily sleep score, cell phone can be the remote and the AI is helping us learn about how important a consistent sleep schedule is. I used to sleep with four pillows, now I sleep with one. Love the bases..

Goes completely fla
These pillows were on sale and had high reviews so I bought a set for myself and my daughter. We both had the same complaint.. once you lay on the pillow for a few minutes if you move around at all, the entire thing goes completely flat and you might as well not have a pillow at all. This might be the worst pillow I have ever slept on.
