Who it fits

Key specs explained for this mattress

Firmness: Firm

This rating indicates a solid, unyielding surface that resists deep sinking. You will feel supported rather than cradled, which keeps your hips from sagging. This firmness level is best for back and stomach sleepers who need to maintain a neutral spine. If you prefer a plush, cloud-like feel, this option may feel too hard. It offers a stable base for proper alignment during sleep.

Thickness: 10 in

A ten-inch profile places this mattress in the standard category for hybrid beds. It provides enough layers for comfort without requiring an extra-tall bed frame. This height is sufficient for most people to get in and out of bed easily. It balances cushioning with the underlying support coils. You should check your bed frame clearance to ensure it fits properly with your existing setup.

Mattress Construction: Hybrid (pocketed coil core)

This design combines a core of individually wrapped coils with foam comfort layers. The coils provide durable support and airflow, while the foam adds pressure relief. This hybrid approach aims to offer the best of both worlds: bounce and breathability. It is generally more durable than all-foam models. You get better edge support and easier movement compared to traditional memory foam mattresses.

Comfort Layer: Gel-infused memory foam

Gel-infused foam is designed to absorb body heat and dissipate it away from your body. This helps keep you cooler than standard memory foam, which can trap heat. The foam still contours to your shape for pressure relief on joints. You benefit from a cooler sleep surface if you tend to overheat at night. This layer sits atop the coils to soften the firm support slightly.

Design and Build Details

The listing describes a hybrid construction that layers gel-infused memory foam over a pocketed coil core. This arrangement targets spinal alignment for back and stomach sleepers. The firm feel resists deep sinking, which helps keep your hips from sagging. You get a stable surface rather than a cradling one. The zoned support system adds targeted contouring for your lumbar area, which prevents heavy sleepers from bottoming out on the coils.

This King-size model measures 76 inches wide and 79.9 inches long, with a height of 10 inches. The total weight is 85.8 pounds. You will find it in White & Blue. The design includes a reinforced steel coil perimeter for edge support. This feature maintains structural integrity when you sit on the side to dress. You will feel a stable, "on-top" sensation instead of sinking into the foam.

According to the listing, the pocketed coils move independently to absorb 90% of motion transfer. This buffer system isolates movement, which is useful for couples. The foams are CertiPUR-US and OEKO-TEX certified, ensuring they are non-toxic and fiberglass-free. The mattress arrives in a box for easier handling. You can choose from other heights like 12 or 14 inches if you prefer a taller profile.

Setup and Everyday Use Guide

You receive this RRESTA mattress in a compressed box. The listing indicates it is a mattress in box design, which means you unpack it and allow the foam and coils to expand to its full 10-inch height. The unit weighs 85.8 pounds, so you may need assistance moving it into position. Its King size measures 76 inches wide and 79.9 inches long, fitting standard King frames.

Daily use relies on the hybrid construction. The individually wrapped pocketed coil core provides a stable surface. You will notice reinforced edge support from the steel coil perimeter. This prevents the "quicksand" sinking feeling common in all-foam beds, making it easier to sit on the edge to dress or get in and out of bed. The firm feel keeps your spine aligned, which is particularly useful for back and stomach sleepers.

For couples, the design isolates motion. Each pocketed coil moves independently, absorbing 90% of motion transfer. If your partner shifts position, you are less likely to feel the disturbance. The gel-infused memory foam layer targets your lumbar zone for pressure relief. This zoned support helps prevent you from bottoming out on the coils. The CertiPUR-US and OEKO-TEX certifications ensure the foams are free from harmful chemicals. You can use the mattress with confidence, knowing it supports long-term stability and breathability without requiring special bedding beyond standard sheets.

Before You Buy This Mattress

You should verify that your bed frame supports a 10-inch hybrid unit. This RRESTA model fits standard King foundations, but you must check weight limits for your slats or box spring. The 85.8-pound weight requires two people for setup. You will need a waterproof protector to maintain the CertiPUR-US foam integrity over time. Regular rotation every three months helps distribute wear on the pocketed coils. This firm option suits those who prefer stability over plush sinking. If you like softer surfaces, consider the 12-inch or 14-inch variations in this lineup. These thicker models offer more comfort layers for side sleepers. Ensure your room has enough clearance for the 76-inch width. Proper airflow around the mattress edges prevents moisture buildup. This guide helps you choose the right firmness and height for your specific sleep needs and body type.

Check before you buy

• Confirm your bed frame supports 85.8 pounds.
• Ensure your room fits the 76-inch width.
• Check slat spacing for hybrid support.
• Buy a waterproof mattress protector.
• Compare thickness options for your sleep style.
